FIELD OF TECHNOLOGY

[0002] This patent application relates to various field systems and methods used for welding pipe pipe segments.

[0003] Pipeline systems that contain extended sections or pipe segments (eg, miles of pipe segments) containing steel pipes, stainless steel pipes or pipes of other types of metals are used to transport liquids such as water, oil, and natural gas between two locations (for example, from a source of origin, which can be located on land and whether on water, to a suitable storage location). The design of piping systems typically comprises joining together pipe segments of the required diameter and longitudinal dimension by means of a welded joint, for example, capable of providing a waterproof seal to the pipe segments being joined.

[0004] When a weld is formed between two pipe segments (for example, two segments having the same or similar cross-sectional dimensions), the end of one pipe section or segment being in close proximity to or in contact with the end of the second pipe section or segment. The pipe segments are held relative to each other and a welded joint is made to join the two ends of the pipe segments using a welding process. The field for performing welding and cleaning the weld is checked. After checking, it is advisable to apply an external protective coating to the welded joint.

[0005] Conventional internal welding machines often include internal alignment mechanisms that are radially outward for connection to the inside of the pipe. The alignment of the two pipe segments is performed internally when the elongate elements of the central element are connected to the inside of the pipe close enough to the mating surfaces of the pipe segment on both sides of the connection, as illustrated in US Pat. No. 3,461,264; 3,009,048; 3,551,636; 3,612,808; and United Kingdom 1261814 (each of which is incorporated herein by reference). To weld the joint, the expander structure must be configured to provide sufficient space to accommodate the rotary torch. An advantage would be to provide internal alignment, providing sufficient space for the rotary or articulated burner, or for external alignment of the pipe segments, in order to eliminate the need for an internal expander, which can cause significant internal interference.

[0006] Moreover, conventional internal welding processes typically include internal or external alignment and installation of the internal welding machine so that the torch is adjusted relative to the mating surface. With such a process, it can be difficult to determine the positioning accuracy of the internal welding machine in general and the welding torch in particular. It is even more difficult to determine the accuracy of the positioning of the welding torch, since the welding torch moves laterally inside the pipe along its orbital path during welding. Thus, it is desirable to provide a system for monitoring the structure or positioning of the edges of the pipe on the contact surface of the pipe to control the welding torch by using the tracked position of the contact surface. In a specific case, it is desirable to first record the profile of the contact surface with a laser before sending a signal to an electronic controller that controls the position and orientation of the welding torch relative to the tracked profile of the contact surface.

[0007] In addition, in conventional pipe welding systems using external alignment mechanisms, typically two segments are held on rollers, and the position and orientation of the segments is controlled until satisfactory alignment is obtained. Despite this, satisfactory alignment, as a rule, is based, for example, on appropriate industrial devices for measuring welding inconsistencies, which are quite accurate, but are controlled and positioned manually in discrete locations, and not over the entire pipe contact surface. In other cases, the contact surface or the structure of the contact surface studied inside the pipe, as a rule, does not give an idea of the quality of alignment. Thus, it is desirable to provide an alignment system in which information on the profile of the contact surface read by the laser would be used as input parameters during the external alignment process. In a particular case, it is desirable to provide information from the laser controlling the welding torch to a controller that will use this information in external alignment control mechanisms.

[0008] Moreover, conventional piping systems for welding pipe segments lack the ability to visually inspect a weld applied by a welding torch. Thus, it is desirable to provide a camera that will follow the welding torch when the weld is applied, and a screen to show the image of the weld to the operator for visual inspection of the quality of the weld. Other advantages of the present invention will become apparent from a review of the present description. Patent advantages are not limited to the benefits covered in this section. Additionally, the benefits discussed in this document should be considered independently of one another and independently of one another, unless expressly stated otherwise in this document. Additional benefits are also described in the claims appended to this application.

[0009] In welding operations, as a rule, pipes are preheated to the required temperature before starting welding work, and a considerable amount of heat is generated during the welding process itself.

[0010] Sometimes, after the completion of welding and cleaning operations, the weld is inspected. It is advisable to check the weld at a temperature close to the operating temperature of the pipe, than at a high temperature of the weld. In this regard, after the welding process, it is desirable to perform cooling before the start of the test. After checking, it is advisable to apply an external protective coating to the joint. To perform such a protective coating, heat is supplied to the pipe to increase its temperature to the temperature necessary to apply a certain external protective coating (for example, polypropylene).

[0011] After such heating, the pipe joint is ideally suited for cooling to a predetermined temperature before additional processing steps to be performed (for example, before wrapping the connected pipe sections or transporting / placing the pipe sections in water, or at another suitable location on the ground).

[0012] During certain pipe processing steps (for example, after welding and before inspection), the outer segments of the pipe to be joined are easily accessible, and cooling of the outer surface is an option. However, during some parts of the process (for example, after applying certain materials to the outer surface of the pipe), the outer surface to which the pipe cooling process is applied is not available.

[0013] Internal cooling may be convenient during certain stages of the processing process (for example, even with external cooling available). Internal cooling inside the pipe requires special approaches, taking into account the size of the pipes and the difficulty of accessing the internal parts of the pipe sections located on or near the welded joint. In this regard, it is highly desirable to provide internal cooling so that during the processing steps when the outer surface of the pipe is not available, cooling could be implemented to quickly ensure the necessary condition of the pipe for subsequent steps requiring low temperatures (e.g. winding).

[0014] Existing pipeline welding verification processes, such as ultrasound testing and radiography, can be quite complex. For example, some processes may require a large team ( for example, 4 or more employees) of highly qualified personnel, which must be delivered to a remote location where the pipeline is being built; field computers may be required, which must be transported by a separate truck to a remote location and used in harsh conditions; provide equipment for testing, which is connected by network wires (“tied”) to dedicated computer equipment and trucks in the field; processes may be ineffective, since each team member may be required only for certain stages of the process; carefully trained technical personnel are required at the work site to decipher the test results; and the required analysis is required, and the results are recorded on the pipe before moving the team to the next weld. Of course, all this statement is of a general nature and not all of these problems exist in all systems.

[0015] Today's pipe joining technologies remain a technical field based on the prevention of errors by workers performing a weld. Some welding technologies require appropriate data management, job control, and job monitoring. Due to such problems, welding quality, lead time and economic performance are also mixed.

[0016] This patent application provides improvements over prior art field systems and methods.

[00236] In one embodiment, the end 1038a of the pipe 1022a and the end 1038b of the pipe 1022a are connected to form an edge for the weld 5236 formed between them. In one embodiment of the invention, the weld edge 5236 may have a V-shaped cross section. In one embodiment, the end 1038a of the pipe 1022a and the end 1038b of the pipe 1022b are designed and prepared to have a J shape so that the weld edge formed when connecting the end 1038a of the pipe 1022a and the end 1038b of the pipe 1022b together has U-shaped configuration. In another embodiment of the invention, the shape of the weld edge depends on the welding parameters or welding conditions.

[00237] As illustrated in FIG. 2, in one embodiment of the invention, the weld metal 1034 is configured to connect a first segment of pipe 1022a and a second segment of pipe 1022b. In one embodiment, the weld metal 1034 may comprise Inconel or an Inconel alloy. In one embodiment of the invention, the weld metal 1034 may comprise a material having higher strength than pipe material. In one embodiment of the invention, the composition of the weld metal 1034 may differ in composition from the material of the pipes. For example, in one embodiment, the weld metal may comprise Inconel or an Inconel alloy, and the material of the first segment of pipe 1022a and the second segment of pipe 1022b may comprise stainless steel.

[00238] In one embodiment, the weld metal 1034 and / or weld 1026 comprises a plurality of layers of a weld 1014, 1016, 1018 and 1020. For example, in one embodiment, the plurality of layers of a weld passage 1014, 1016, 1018 and 1020 may include a weld root passage 1014, a hot passage 1016, one or more layers of filling passage 1018, and a layer of facing passage 1020, as will be described in more detail below. The weld bead layer (s) may be used interchangeably in this document as the bead layer (s). In one embodiment of the invention, the passage of the weld (for example, the passage when welding the root of the seam, the hot passage filling the passage (s), the facing passage) may be a single passage of the welding tool or welding system along the weld joint 1026. In one embodiment of the invention, a weld bead or weld is formed as a result of each pass of the weld.

[00239] In one embodiment of the invention, as illustrated in FIG. 1A, 1B, and 2, a method 1000 for welding pipe sections or segments 1022a and 1022b together typically includes a weld root pass 1002, a hot pass 1004, a fill and a face pass 1006, a weld check 1008, a procedure heating 1010 and coating procedure 1012. In one embodiment of the invention, the filling passage and facing passage 1006 may include one or more filling passage of the weld 1006a and the facing passage of the weld 1006b. In one embodiment of the invention, method 1000 is typically a multi-pass weld or multi-layer weld procedure, which includes, for example, a weld root pass 1002, a hot pass weld 1004, and a filling and facing pass 1006.

[00240] In one embodiment, one or more weld passes (for example, a weld root pass, a hot pass filling the passage (s), a facing pass) of the multi-pass or multi-layer weld method 1000 may be performed with the same welding system or tool at different times. In one embodiment of the invention, the weld passes can be performed sequentially with the same system or tool. For example, in one embodiment of the invention, the passage procedures when welding the root of the seam and the hot passage can be performed sequentially by the internal welding system 5004 (as will be described in more detail below) inside the pipes. In one embodiment of the invention, the filling and facing passage procedures may be performed sequentially by an external welding system 7500 outside the pipes.

[00241] In one embodiment, the internal welding system 5004 is typically configured to weld the pipe segments 1022a and 1022b inside the pipe 1024, and the external welding system 7500 is typically configured to weld the pipe segments 1022a 1022b outside the pipe 1024 In one embodiment, a K-shaped weld bead or layer is formed by welding performed by an internal welding system 5004, and a J-shaped weld is formed by welding performed by an external welding system 7500 a seam or layer.

[00242] In one embodiment of the invention, the hot, filling and facing pass procedures can be performed sequentially by an external welding system 7500 outside the pipes, with only the passage procedure when welding the root of the seam being performed by the internal welding system 5004 (as will be described in more detail below) inside the pipes .

[00243] In one embodiment of the invention, one or more weld passes (for example, a weld root pass, a hot passage filling the passage (s), a facing pass) of the multi-pass or multi-layer weld method 1000 may be performed by different welding systems or tools at the same or different time. In one embodiment of the invention, weld passes can be performed sequentially by different welding systems or tools.

[00244] In one embodiment of the invention, each of the hot, filling, or facing pass procedures is performed in its respective welding booth outside the pipes. In one embodiment of the invention, the welding cabin is a relatively small chamber, approximately 12 feet wide, 10 feet long and 8 feet high, in which an external welding system is installed and moves from one welded joint to another welded joint via a tail platform. The welding cabin, as a rule, is a frame made of light metal, covered with thin sheet metal. The welding cabin has a special floor designed for upward rotation, which allows the welding cabin to lower onto the pipes and then turn back to gain convenient access to the pipe.

[00313] In one embodiment, the procedure for lowering the pipeline 1050c is adapted to position / lower the pipeline into a previously dug trench.

[00314] In one embodiment of the invention, the condition / conditions for performing pipeline welding can be classified into five categories, called: onshore main pipeline welding procedure, onshore butt welding procedure, onshore pipe welding base main welding procedure, pipeline lash welding procedure on the coastal pipe welding base and welding procedure on a barge.

[00315] The onshore main pipeline welding procedure is illustrated in FIG. 3. The procedure for welding the main pipeline on land is usually carried out at the level of the earth's surface and next to the previously dug trench in which the pipeline will be located. In one embodiment of the invention, surface pipelines are welded together in sections, for example, up to 1 mile in length. Ground welding stations are located next to each other. The procedures performed before and after welding, the welding process onshore are separated from the actual welding procedure so that the procedures performed before and after welding can be performed at their own speed. After the segments of the pipeline are welded together, they lower the previously dug trench.

[00316] A procedure for welding pipe lashes is illustrated in FIG. 4. The procedure for welding lashes of the pipeline on land, as a rule, is carried out in a previously dug trench in which the pipeline will be located. In other words, sections or segments are cut to the desired length and welded together in a previously dug trench.

[00317] The welding procedure of the main pipeline at the onshore pipe welding base is illustrated in FIG. 5. The welding procedure for the main pipeline at the onshore pipe-welding base is usually carried out in an environment close to the factory one. All actions of the welding procedure of the main pipeline at the onshore pipe-welding base take place inside a continuous production process, approximate and appropriate to the factory conditions. For example, pipes are welded, inspected and coated along the assembly line to form a pipe whip (for example, reaching, in some cases, 7 kilometers). Scourges of pipes are stored until they are wound on a ship for transport to their destination. In other words, when the ship / barge is far from the onshore pipe-welding base, the welded pipes are stored in long sections. The lashes of pipes are wound onto large coils on barges (usually in the form of a J-shaped stacking) and unwound when the barge reaches the place of work.

[00318] A procedure for welding pipe lashes at an onshore pipe welding base is illustrated in FIG. 6. The procedure for welding pipe lashes at an onshore pipe-welding base is used to join the pre-assembled sections of the pipeline or segments together, in the form in which they will be wound onto the ship / vessel, which, as a rule, transports the pipeline to its final destination. The compound cools after coating, which reduces the winding speed. All welding procedures for pipeline lashes at the onshore pipe welding base are performed at the same station.

[00319] The barge welding procedure is illustrated in FIG. 7. The welding procedure on a barge, as a rule, is carried out in conditions close to the factory ones, on board a floating base. All actions of the welding procedure on a barge, as a rule, are carried out inside a continuous production process, approximate and corresponding to the factory conditions. The pipeline is located at its final destination when separated from the vessel.

[00320] Each of these pipeline weld locations may contain one or more of the procedures described with respect to FIG. 1A and 1B.

For example, an ultrasonic, radiographic, or magnetic inspection of a weld area may be used for verification. Any defects found during the weld inspection procedure are eliminated during the weld repair procedure. Welded pipes are coated with a fused epoxy coating. The fused epoxy coating is applied to the (heated) protruding end of the welded pipe so that the fused epoxy coating adheres to the outer surface of the inside of the pipe. The coating procedure is performed by an independent team that works after the repair team. A pipeline loan is lowered into a previously dug trench. The pipeline lowering procedure can be performed by an independent team that works in front of the coating team.

[00325] As illustrated in FIG. 4, the onshore pipe lash welding procedure begins with the pipe preparation procedure.

In one embodiment of the invention, the internal welding system 5004 places a weld (for example, by arc welding with a metal electrode in a GMAW shielding gas medium) from within the pipe segments 1022a, 1022b on the side surface or mating surface of the pipe segment 1022a, 1022b and in the v-shape the gap formed by the beveled edge / chamfer of the two pipe segments 1022a, 1022b (a different cross-sectional shape may be used, different from the v-shaped gap).

[00349] FIG. 9A illustrates a partial cross-sectional view of conduit 1024 showing perfect alignment of the welding head 5502 of the internal welding system 5004 with respect to the internal groove of the weld 5228 and 5232 (along the longitudinal axis AA of the pipes 1022a, 1022b). In the illustrated embodiment, the pipes 1022a, 1022b are perfectly aligned with each other and have no step transition (i.e., height differences between the chamfers of the pipes 1022a, 1022b after aligning the pipe).

[00350] In one embodiment of the invention, the field system 5000 may include external clips 5302 used to securely fix the pipes together (external to the pipes). In one embodiment of the invention, the outer clamps 5302 have rods across the weld joint, and welding can be performed manually. In one embodiment, external clips 5302 may be hydraulically actuated or may be mechanically actuated (eg, using a hand lever). For example, in one embodiment of the invention, the outer clips 5302 may be tip-tone clips, as illustrated in FIG. 7A and 7B.

[00351] In one embodiment, the internal welding system 5004 is connected to an external structure / system (ie, external to the pipes to be welded 1022a, 1022b) by means of a halyard 5034 (as illustrated in Fig. 10-1). In one embodiment, the external system is a uLog remote processing system. In one embodiment, the halyard 5034 may have a length in the range of 40 to 80 feet (for example, for a pipe whose length is 40 to 80 feet). In one embodiment, the halyard 5034 may be referred to as a “drive rod.” In one embodiment, the drive rod / halyard 5034 may be rigidly connected to the internal welding system 5004. In other words, the drive rod / halyard 5034 is a permanent element of the internal welding system 5004. In one embodiment, the halyard 5034 comprises a structural tubular member, protects all cables, wires and hoses (for example, which connect the external structure / system and internal welding system 5004) from damage.

[00352] In one embodiment, when the internal welding system 5004 moves from one pipe joint (welded) to the next pipe joint (welded), the halyard 5034 is disconnected at the DP disconnect point (as illustrated in Fig. 10-2). This disconnection helps to place the new / incoming pipe segment 1022a in a certain position with respect to the first pipe 1022b. FIG. 10-2 illustrate that cables, hoses and wires (for example, which connect the external structure / system and internal welding system 5004) at the end of each drive rod / halyard 5034 are disconnected and that the new / incoming pipe segment 1022a is positioned in relation to the first pipe 1022b.

[00353] As illustrated in FIG. 10-3, in one embodiment of the invention, after the incoming pipe 1002a placed in a certain position with respect to the first pipe 1002b, the halyard 5034 can protrude / stretch from the incoming pipe 1002a at a distance HP. In one embodiment of the invention, the distance HP at which the halyard 5034 can protrude / stretch from the incoming pipe 1002a is in the range of 1 to 5 feet.

[00354] The halyard 5034 is typically used to supply fluid (compressed air), transmit electrical signals and / or transmit communication signals between an external structure / system and internal welding system 5004. In one embodiment of the invention, the lash welding system of pipe 3001 is not contains drive draft or halyard.

[00355] For example, the halyard 5034 may include a welding power supply line configured to supply power to the welding torches. In one embodiment, the halyard 5034 contains three welding power lines for independently supplying power to three connected welding torches in the internal welding system 5004. In one embodiment, the number of welding power lines in the halyard 5034 may vary and depend on the number of welding torches in the internal welding system 5004.

[00356] In one embodiment, the halyard 5034 may include communication lines configured to communicate with a measurement sensor 5056, a monitoring camera 5112, and / or other electronic modules (eg, to start or stop welding) of the internal welding system 5004. B one embodiment of the invention, data exchange with an internal welding system 5004, including data exchange with a measuring sensor 5056, a control camera 5112, and / or other electronic components of the internal welding system 5004, may perform Wirelessly. It should be understood that if multiple welding torches are provided, then a plurality of measurement sensors / lasers 5056 are also provided.

[00357] In one embodiment, the halyard 5034 may include a fluid supply line configured to provide compressed air to the internal welding system 5004. In one embodiment, the halyard 5034 may include other (separate) power lines configured to suppress electricity for 5116 batteries to recharge them. In one embodiment of the invention, a separate power line for recharging batteries 5116 is optional. In one embodiment, the halyard 5034 may comprise a separate power line configured to supply power to one or more electronic modules and / or motors of the internal welding system 5004. In another embodiment, a separate power line is optional.

[00358] In one embodiment, an internal welding system 5004 is used for pipes having an internal diameter of 26 to 28 inches with a pipe wall thickness of 0 to 1 inches. In this regard, the internal welding system 5004 is configured to fit a hole size of 24 to 28 inches. In one embodiment, an internal welding system 5004 is used for pipes having an inner diameter of 24 inches or less with a pipe wall thickness of 0 to 1 inch. In one embodiment, an internal welding system 5004 is used for pipes having an outer diameter of 24 inches or less. In one embodiment, an internal welding system 5004 is used for pipes having an outer diameter of 26 to 28 inches.

[00359] FIG. 10A illustrates a constructed internal welding system 5004, sized and placed in pipes having an internal diameter of 26 inches with a wall thickness of 1 inch. For example, in one embodiment of the invention, the outer diameter of the frame structure of the internal welding system 5004 is 23.32 inches for pipes with an inner diameter of 26 inches (with a wall thickness of 1 inch). For example, for a pipe with an internal diameter of 26 inches (with a wall thickness of 1 inch), the outer diameter of the frame structure (not having its own wheels) of the internal welding system 5004 is 23.32 inches.

[00360] FIG. 10B illustrates an internal weld system 5004 being constructed, sized and placed in pipes having an internal diameter of 24 inches with a wall thickness of 1 inch. For example, in one embodiment of the invention, the outer diameter of the frame structure of the internal welding system 5004 is 21.32 inches for pipes with an inner diameter of 24 inches (with a wall thickness of 1 inch). For example, for a pipe with an inner diameter of 24 inches, the outer diameter of the frame structure (not having its own wheels) of the internal welding system 5004 is 21.32 inches.

[00361] In one embodiment, the frame diameter of the internal welding system 5004 may depend on the ability of the internal welding system to pass through the bends of the pipe. In one embodiment, the standard minimum bend radius of the pipe is 30 times D, where D is the outside or outside diameter of the pipe. In other words, the radius of the axis of rotation of the pipe is 30 times larger than the outer or outer diameter of the pipe. For example, for a pipe with an outer or outer diameter of 26 inches, the minimum bending radius required to pass the 5004 internal welding system is 780 inches (i.e. (26 inches) x 30). For example, for a pipe with an external or external diameter of 24 inches, the minimum bending radius required to pass the 5004 internal welding system is 720 inches (i.e. (24 inches) x 30). In one embodiment of the invention, the length of the frame of the internal welding system 5004 is limited by its placement.

[00362] In one embodiment of the invention, as illustrated in FIG. 1 ° C and 10D, the field system 5000 may include a platform 5330 for transporting and moving the first pipe 1022a and the second pipe 1022b. In one embodiment of the invention, the platform 5330 is configured to bring the second pipe 1022a from the second end 1038b of the end of the first pipe 1022b after installing the frame of the internal welding system 5004 at the second end of the first pipe 1022b. In one embodiment, platform 5330 may be referred to as a “docking module” (LUM).

[00363] In one embodiment of the invention, if necessary, several platforms can be used to hold the pipes 1022a, 1022b. For example, if the pipe 1022a, 1022b is small and flexible, at least four platforms can be used that are installed at intervals along the entire length of the pipe 1022a, 1022b. If the pipe 1022a or 1022b is large and rigid, only two platforms can be used along the entire length of the pipe 1022a, 1022b.

[00364] In one embodiment, two platforms can be used to transport and move the pipe so that each platform is mounted at the end of the pipe. In one embodiment of the invention, three platforms are used to transport and move the pipe so that two platforms are installed at the ends of the pipe and one platform is installed in the central part of the pipe section. In one embodiment of the invention, the centrally located platform is configured to provide only support and without connectivity. In one embodiment of the invention, the platform 5330 used for the incoming pipe 1022a can be fully configured to transport, move and bring the incoming pipe 1022a to the second end of the first pipe 1022b (after the frame assembly of the internal welding system 5004 is mounted on the second the end of the first pipe 1022b) and re-aligning the incoming pipe 1022a in the event that the profile data of the preliminary weld reveal the need for adjustment.

[00365] In one embodiment of the invention, the platform 5330 may comprise a set of external to the tubes 1022a, 1022b driven rollers 5332. In one embodiment, the rollers 5332 of the platform 5330 may be referred to as “external pivoting members”. In one embodiment of the invention, the outer surface 5346 and / or 5348 (as illustrated in FIG. 2G) of the first pipe 1022a and / or the second pipe 1022b comes into movable contact with the outer (s) rotary (s) element (s) 5332, which helps to adjust the relative position of the pipes 1022a, 1022b based on instructions from one or more processors 5140.

[00366] In one embodiment, the platform 5330 comprises a fixed frame 5334 configured to rigidly connect to a surface (eg, base), a first movable frame 5336 movable to position the pipe in a horizontal plane, and a second movable frame 5338 made with the possibility of positioning the pipe in a vertical plane.

[00367] In one embodiment of the invention, platform 5330 may be hydraulically actuated. For example, hydraulic cylinders 5340 located on the sides of platform 5330 may be configured to move a second movable chassis 5338. In one embodiment of the invention, hydraulic cylinder (s) 5342 located below platform 5330 may be configured to move a first movable platform 5336. In one embodiment, the movement of platforms 5330 (placed at both ends of the pipes) can be coordinated to adjust the linear movement of the pipe 1022a or 1022b in all three directions (up-down, left-right, back-forward) and adjust the angular movement of the pipe 1022a or 1022b in two directions (tilt in the vertical and horizontal plane)).

[00368] In one embodiment, the platform 5330 is operatively coupled to one or more processors 5140. In one embodiment, the platform 5330 is connected wirelessly or using a wired connection to one or more processors 5140 such that if data the profile of the pre-weld is necessary to adjust, the hydraulic cylinders 5340 and 5342 are actuated to move and re-align the incoming pipe 1022a based on the profile data I'm pre-weld. In one embodiment of the invention, externally mounted rollers 5332 may be operatively coupled and controlled by one or more processors 5140 by means of a first movable chassis 5336 and a second movable chassis 5338.

[00369] In one embodiment of the invention, platform 5300 may be electrically powered. For example, FIG. 73 illustrates electrically powered platforms 6010A and 6010B. In one embodiment of the invention, the platform rollers 6010A and 6010B can be controlled by motors for linear and / or angular movement of the pipe 1022a or 1022b. In one embodiment of the invention, the 6010A 6010B platforms may comprise motors operably coupled to a ball screw, allowing the first movable frame and / or the second movable frame to be moved.

[00370] In general, when aligning pipes for a welding procedure, two alignment errors may occur, for example, an angle alignment error of a pipe and a pipe positioning error. As illustrated in FIG. 10E, an angular alignment error results in a gap 5344 on one side of the pipe. As illustrated in FIG. 10F, a positioning error results in a step transition, i.e., a protrusion on one side (e.g., 1022b), and a depression on the other side (e.g., 1022a).

[00371] In one embodiment, platforms 5330 or platforms 6010A and 6010B are used in alignment of pipelines and onshore welding procedures. In conditions of installing the pipeline at sea, both errors - angular alignment and positioning - can be corrected by transmitting control signals from one or more processors 5140 to platform 5330 or platforms 6010A and 6010B (to control the corresponding rollers 5332). Thus, one or more processors 5140 are configured to adjust the relative position between the pipes (to correct alignment errors) by controlling platform 5330 or platforms 6010A and 6010B. In one embodiment of the invention, one or more processors 5140 are configured to actuate platforms 5330 for relative movement of the first pipe 1022a and the second pipe 1022b between each other based on the profile of the preliminary weld to change the area of the contact surface 5136 between the pipes 1022a, 1022b before welding operations based on instructions from one or more processors 5140.

[00372] In one embodiment, the pipes 1002a, 1002b may be aligned with a tap and clamp (internal or external). In one embodiment, the clamps can be constructed and mounted to align the two pipes 1022a, 1022b horizontally and vertically. In one embodiment of the invention, the crane is configured to control axial position and at two angles (tilt in the vertical and horizontal plane).

[00373] In one embodiment of the invention, as illustrated in FIG. 11, the internal welding system 5004 comprises a front section 5006, a center section 5008, and a drive section 5010.

[00374] In one embodiment, the carcass elements of the frontmost section 5006, the central section 5008, and the drive section 5010 together may be referred to as the carcass assembly or carcass of the internal welding system 5004. In one embodiment, the carcass or carcass assembly of the internal welding system 5004 may be configured to support all components of each of the sections: the front section 5006, the central section 5008 and the drive section 5010. In one embodiment of the invention, the frame or frame assembly of the internal welding system 5004 may comprise the most forward section of the frame 5026 (as illustrated in FIG. 12), the front frame section 5068 (as illustrated in FIG. 23) and the frame drive section 5278 (as illustrated in FIG. 32A). In one embodiment of the invention, the carcass or carcass assembly of the internal welding system 5004 is configured to fit inside pipes 1022a, 1022b.

[00375] In one embodiment, the frontmost section 5006 is a section where external cables, wires and hoses from an external system / structure (external to the pipes to be welded) are connected. In one embodiment of the invention, the frontmost section 5006 is configured to accommodate all components providing a weld, as described in more detail below. In one embodiment of the invention, the central section 5008 is configured to align pipe segments 1022a, 1022b and perform welding procedures. In one embodiment of the invention, the drive section 5010 is configured to move the internal welding system 5004 from one pipe joint to the next pipe joint. In one embodiment, the drive section 5010 is also configured to accommodate batteries, compressed air, and shielding gas, which are part of the internal welding system 5004 necessary for operation.

[00376] In one embodiment, some components of the internal welding system 5004 are arranged such that half of the components are located in the front section 5006 and the remaining components are located in the central section 5008. In one embodiment, some components of the internal welding system 5004 placed in one of the three sections of the internal welding system 5004, but connected to the other three sections of the internal welding system 5004. For example, the components of the internal welding system 5004 are placed in the front section 5006 of the internal welding system 5004 and are only connected to a central section 5008 of the internal welding system 5004.

[00377] FIG. 12 illustrates an enlarged view of the front section 5006 of the internal welding system 5004. In one embodiment, the front section 5006 of the internal welding system 5004 includes a coupling device 5012, a front electronic module 5014, a contact ring 5016, a front clamp control valve 5018, a feed assembly wire 5020, front position sensor 5022, adjustable guides 5024, the front section of the frame 5026, guide rollers 5028, front rotation motor 5030 and front rotary coupling 5032. In one embodiment, the real tion of the invention, the most front electronic module 5014 may include one or more processors 5014. In one embodiment, the control valve front clip 5018, the front position sensor 5022 and the forward rotation of the motor 5030 can be operably linked to one or more processors 5140.

[00378] FIG. 13-22 illustrate the various components of the front section 5006 of the internal welding system 5004. For example, FIG. 13 illustrates a coupling device 5012, FIG. 14 illustrates a front rotary clutch 5032, FIG. 15 illustrates the front contact ring 5016, FIG. 16 illustrates the frontmost section of the chassis 5026, FIG. 17 illustrates adjustable guides 5024, FIG. 18 illustrates guide rollers 5028, FIG. 19 illustrates a front rotation motor 5030, FIG. 20 illustrates a front clamp control valve 5018, FIG. 21 illustrates a forward position sensor 5022, and FIG. 22 illustrates a wire feed assembly 5020, respectively.

[00379] FIG. 11A illustrates a view of a halyard 5034 in which an internal welding system 5004 is configured to connect to a first end 5035 of a halyard 5034, and an operator control system 5039 configured to connect to a second end 5037 of a halyard 5034. In one embodiment, the first end 5035 of a halyard 5034 is connected to the coupling device 5012 by the front section 5006 of the internal welding system 5004. In one embodiment of the invention, the exchange of data (internal welding system 5004) with the Ulog system is arranged to organize it by Nogo or more processors, or modules in the operator control system 5039. In one embodiment, control system 5039 of the operator is located outside with respect to the welded pipes 1022a, 1022b.

[00380] In one embodiment of the invention, the most front section of the frame 5026 is constructed and mounted to accommodate / support all components of the front section 5006 of the internal welding system 5004. In one embodiment, the most front section of the frame 5026 is constructed and mounted to provide the mounting point for all components in front of the 5004 internal welding system and to protect these components from damage. In one embodiment of the invention, the frontmost section of the chassis 5026 is constructed and mounted to guide new pipe segments to align with previous / existing segments. In one embodiment of the invention, the frontmost section 5026 may be made of steel or other materials, as will be appreciated by those skilled in the art.

[00381] In one embodiment of the invention, the frontmost section of the frame 5026 is constructed and mounted in such a way that it contains a conical nose cone that allows the internal welding system 5004 to move easily in new pipe segments during connection / welding of new pipe segments with previous / existing pipe segments. In one embodiment, the cone-shaped nose cone 5026 may serve as an alignment structure configured to facilitate alignment of the second pipe 1022b with the first pipe 1022a. In one embodiment, the cone-shaped nose cone is adapted to extend outward from the second end of the first pipe 1022a, which helps align the second pipe 1022b with respect to the first pipe 1022a.

[00382] In one embodiment of the invention, as illustrated in FIG. 12, the frontmost section of the frame 5026 includes a sensor 5352 configured to detect the end of the pipe when the frame of the internal welding system 5004 returns to the pipe hole after welding the previous pipe. In one embodiment of the invention, the sensor 5352 may be configured to be movable together with the frame of the internal welding system 5004. In one embodiment of the invention, the sensor 5352 is operatively coupled or connected to one or more processors 5140.

[00383] In one embodiment, the sensor 5352 may be a rotary switch. For example, the rotary switch may have a protruding downward rod or wire biased toward the inner surface of the pipe and made to move by touching the inner surface of the pipe until it reaches its edge, and extend down after reaching the edge of the pipe to act rotary switch, thus detecting the end of the pipe. For example, when the very front section of the carcass 5026 reaches the end of the pipe, part of it will slide out of the pipe in order to take on the next welded pipe, while the wire is configured to extend out of its normal position to detect the end of the pipe. In another embodiment, the sensor 5352 may be a linear displacement sensor configured to be operatively coupled to the wheels / rollers of the internal welding system 5004 to determine the distance that the internal welding system 5004 travels and use this information to determine / detect the end of the pipe of known length .

[00384] In one embodiment, the sensor 5352 is configured to detect an area of the contact surface 5136 between the pipes 1022a, 1022b. In one embodiment, one or more processors 5140 is configured to control drive motors 5124 to move the frame of the internal welding system 5004 through at least one of the pipes 1022a, 1022b until the sensor 5352 detects a contact area 5136. B in one embodiment, the sensor 5352 is configured to detect the placement of the internal welding system 5004 in the area of the contact surface between the two pipes 1002a, 1002b. In one embodiment, the sensor 5352 may be a measurement sensor 5056. In one embodiment, the sensor 5352 may be a laser. In one embodiment of the invention, the sensor 5352 may be a monitoring chamber 5112. In one embodiment of the invention, the measuring sensor 5056 and / or the monitoring chamber 5112 are configured to also perform the measuring functions of the sensor 5352.

[00385] In one embodiment of the invention, as illustrated in FIG. 12, the end 5208 of the front section of the chassis 5026 is connected to the flange portion 5210 (as illustrated in FIG. 23) of the front clip 5142 of the central section 5008. In one embodiment, the end 5208 of the front section of the frame 5026 is connected the flange portion 5210 of the front clamp 5142 of the center section 5008 using fasteners, for example, bolts 5212 (as illustrated in FIG. 23).

[00386] The front rotary clutch 5032 in the very front section 5006 is illustrated in FIG. 12 and 14. A rotary coupling is generally a coupling or joint constructed and mounted so as to allow rotation of two combined / connected elements. The rotary coupling is constructed and mounted in such a way as to provide a seal between the stationary supply channel (pipe or pipe) and the rotating element (drum, cylinder or spindle) to prevent the ingress of fluid and / or its leakage from the rotating element. Fluids that are typically used with rotary couplings include compressed air and purge gas. A rotary coupling typically comprises a housing, a shaft, a seal, and a bearing. Bearings and seal mounted around the shaft. Bearings are used so that the rotating joint element, both the shaft and the housing, can rotate. Seals are constructed and mounted to prevent fluid (such as compressed air or purge gas) from leaking out through the rotary clutch during operation. During operation, the rotary clutch is clamped to the inlet valve to close to the exhaust valve. At this time, the fluid enters the rotary clutch from its source and is held inside the rotary clutch during its movement. This fluid leaves the rotary sleeve when it intersects with the valve bore during rotation, and more fluid enters the rotary sleeve again during the next rotation.

[00387] In one embodiment of the invention, the front rotary clutch 5032 is configured to allow passage of compressed air through it. In one embodiment of the invention, the front rotary sleeve 5032 (for example, described with respect to FIG. 25) is constructed and mounted to receive compressed air from the rear rotary sleeve 5072 (for example, via the rear contact ring 5080, the rotary hub 5078 and the front contact ring 5016 ) The rear rotary clutch has mainly the same components and works mainly in the same way as the front rotary clutch 5032, and therefore is not illustrated in more detail as the front rotary clutch 5032.

[00388] In one embodiment of the invention, the front rotary clutch 5032 is constructed and mounted to transfer part of the compressed air received to the front clamp control valve 5018 (to actuate and control the front clamp 5142) through the valve 5204. In one embodiment, the front the rotary coupling 5032 is constructed and mounted to transfer the remaining portion of the received compressed air to a compressor or an external balloon of the air supply system 5029 (as illustrated in FIG. 70) for replenishing the systems (E.g., filling the cylinder with compressed air) through a valve 5204. In one embodiment, the remaining portion of compressed air supplied to the compressor or the air supply cylinder 5029 (as illustrated in FIG. 70) through the front rotary clutch 5032.

[00389] In one embodiment of the invention, as illustrated in FIG. 70, two valves 5115 and 5117 are configured to be closed at the beginning of the replenishment procedure. During the replenishment procedure, compressed air from the cylinder of the air supply system 5029 passes through the valve 5115, 5117 and 5204 to the front rotary coupling 5032, from the front rotary coupling 5032 to the rear rotary coupling 5072, and then through valves 5198,5196, 5194 and 5113 to a cylinder with compressed air 5128 to replenish the cylinder with compressed air 5128 compressed air. In one embodiment of the invention, the pressure along the entire fluid path (or fluid transfer line) between the external balloon of the air supply system 5029 and the compressed air bottle 5128 is maintained at the pressure level in the balloon during the replenishment procedure.

[00390] In one embodiment, the front rotary sleeve 5032 in the very front section 5006 is also configured to allow compressed air from the halyard 5034 to enter a wire feed unit 5020 rotatably mounted on the rotary hub 5078 of the central section 5008.

[00391] The front contact ring 5016 in the very front section 5006 is illustrated in FIG. 12 and 15. The slip ring is an electromechanical device (electrical connection), built and mounted to transfer electrical energy and communication signals from a stationary structure to a rotating structure. The slip ring can be used in any electromechanical systems that require free continuous rotation during the transmission of energy and / or data signals. The contact ring contains a stationary structure (contact brush), which rubs along the outer diameter of the rotating structure. Since the rotating structure makes a revolution, an electric current or signal is conducted through the stationary structure to the rotating structure making the connection. The stationary structure may be a graphite or metal contact (brush), and the rotating structure may be a metal ring.

[00444] In one embodiment, the front rotation motor 5074 has an electric motor comprising a rotor, a rotary shaft rotatable by the rotor, and a drive gear supported by the rotary shaft and containing teeth thereon. The teeth on the drive gear are constructed and mounted to mesh with the teeth formed on the driven gear member 5079 of the rotary hub 5078 to transmit torque from the rear rotation motor 5074 to the rotary hub 5078.

[00445] In one embodiment of the invention, the swivel hub 5078 is constructed and mounted to rotate during welding, during scanning procedures before welding and after welding. In one embodiment, the swivel hub 5078 is located between the first and second clamps 5142 and 5144. Since the first and second clamps 5142 and 5144 are not physically connected to each other, the front rotation motor 5030 and the rear rotation motor 5074 at each end of the rotary hub 5078 synchronized to hold the two pipes 1022a, 1022b from moving relative to each other. In one embodiment of the invention, two pipe engagement devices 5142, 5144 can rotate relative to each other by rotating the front rotation motor 5030 and the rear rotation motor 5074, for example, at different speeds and / or in different directions. In one embodiment of the invention, only when the front rotation motor 5030 and the rear rotation motor 5074 rotate at the same speed in the same direction, the welding torch 5502 and the measuring sensor 5056 rotate along the contact surface 5136 between the pipes 1022a, 1022b (for example without moving the gearing devices of the pipe 5142, 5144).

[00446] In one embodiment, the center portion 5077 of the swivel hub 5078 comprises slots / openings through which shielding gas hoses, bowden tubes (guides), welding power cables, motor cables, sensor cables, and camera cables are calculated .

[00447] In one embodiment of the invention, as illustrated in FIG. 23, 24 and 30, the front clip 5142 has a hollow configuration.

In one embodiment, the hole 5082 of the front clamp 5142 is also constructed and mounted to provide for the use of structural elements necessary to hold the mass of the front half of the internal welding system 5004, as well as to maintain alignment of the two halves / segments of the weld pipe 1022a, 1022b. In one embodiment of the invention, the front and rear clamps 5142, 5144 are constructed and mounted for mounting on a rotary hub 5078, for example, using pre-tensioned bearings 5108, 5098 with preload to provide rigidity.

[00448] In one embodiment, the inner surface 5130, 5132 of the first pipe 1022a and / or the second pipe 1022b is engaged and controlled by the first clamp 5142 and the second clamp 5144, respectively, to adjust the relative positioning of the pipes based on instructions from one or more processors 5140. In one embodiment, adjusting the relative positioning of the pipes 1022a, 1022b is achieved without disengaging the first gearing device of the pipe 5144 from the inner surface 5132 of the first pipe 1022b and without being disengaged a second gearing device for the pipe 5142 from the inner surface 5130 of the second pipe 1022a. This can be done since the rotation motors 5030 and 5074 are configured to rotate the pipes 1022a, 1022b without disengaging the pipe engaging devices 5144, 5142, as described in this patent application.

[00449] In one embodiment of the invention, as illustrated in FIG. 23, 24, and 30, front clamp 5142 typically comprises a piston 5084, cylinder 5086, liner 5088, fingers of clamp shoe 5090, levers 5092, shaft 5094, hub 5096, front bearing 5098, arachnoid 5100, casing 5102, front disc 5104, rear disk 5106, rear bearing 5108 and hub 5110.

In one embodiment, one of the clamps 5142, 5144 may be referred to as a “first clamp”, and the other of the clamps 5142, 5144 may be called a “second clamp”. In one embodiment, the clips 5142, 5144 of the internal welding system 5004 may either be individually or collectively referred to as a “brake system” of the internal welding system 5004, which holds the frame of the internal welding system 5004 in position within the pipe 1022a, 1022b. In one embodiment of the invention, the front and rear clamps 5142, 5144 are radial clamps that mesh with the inner surface 5130, 5132 of the pipes 1022a, 1022b, respectively, to keep the internal welding system 5004 from moving.

In one embodiment of the invention, one or more processors 5140 are configured to control the braking system of the internal welding system 5004 to lock the frame of the internal welding system 5004 to a specific position within the pipes 1022a, 1022b from movement that determines the position of the measurement sensor 5056 with respect to the contact area surface 5136 to enable the measuring sensor 5056 to detect the profile of the area of the contact surface 5136 between the pipes 1022a, 1022b.

[00470] FIG. 33 illustrates a view of a central section 5008 of an internal welding system 5004 located within pipe segments 1022a, 1022b, where some components of the central section 5008 are not illustrated for clarity. For example, front and rear clamps 5142, 5144, pivot hub 5078, welding head assembly 5500, measuring sensor 5056 and monitoring chamber 5112 in FIG. 33.

[00471] In one embodiment of the invention, the field system 5000 for welding two pipes comprises a computer system 5138 that facilitates welding. In one embodiment, the computer system 5138 comprises one or more processors 5140 communicatively coupled to a welding system 5004. In one embodiment, the computer system 5138 and its one or more processors 5140 may be communicatively coupled to welding system 5004 (and one or more of its components) via one or more wired or wireless communication channels. As an example, wired communication channels may comprise one or more Ethernet channels, a coaxial communication channel, an optical fiber communication channel, or other wired communication channels. As another example, wireless communication channels may include one or more Wi-Fi communication channels, a Bluetooth communication channel, short-range communication channels (NFC), cellular communication channels, or other wireless communication channels. In one embodiment of the invention, one or more components of the welding system 5004 may be interconnected via one or more of the aforementioned wired or wireless communication channels. In one embodiment of the invention, it may be useful to use one or more wireless communication channels to enable one or more processors 5140 or one or more components of the welding system 5004 to communicate with each other to reduce the number of communication cables in the welding system 5004 to reduce risk potential cable tangling, resulting in delays or damage to other components of the 5004 welding system. For example, by reducing the number of communication cables 5004 s in a welding system, in some embodiments of the invention may decrease the potential tangling of cables during rotation measuring devices (e.g. laser measurement, monitoring cameras or other measuring device), a welding torch or other components of the welding system 5004.

[00472] In one embodiment, the computer system 5138 and its one or more processors 5140 can be located in the field system 5000.

In one embodiment, one or more processors 5140 may comprise a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information and, state machine, and / or other mechanisms for electronic information processing.

[00473] It should be understood that in the context of this document, the term "one or more processors" may mean a separate embedded processor, local to a specific system or component described herein, external and local to a specific system or component described in this document, or located remotely with respect to a particular system or component described in this document. In addition, the connection between one or more processors may be wired or wireless. Additionally, the term “one or more processors” may also mean a plurality of embedded and local processors, a plurality of separate and local processors, a plurality of processors located remotely, or any combination of an embedded (and local), separate (and local) and remote processors. Relative to embedded processors, such processors mean processors that are physically moving (i.e. physically connected and moving) along with a particular system or component. For individual processors, this means processors that are local to the production site and communicate wirelessly with the integrated electronic components. Separate processors are also called electronic components associated with the embedded system (for example, by means of drive traction), and which are local to the production site. When viewed in a different light, if the processor moves with the drive rod, it should also be considered as an “embedded” processor.

[00474] In one embodiment of the invention, the first pipe engaging device 5002 is adapted to mesh with the inner surface 5130 of the first pipe, allowing the first pipe engaging device 5052 to be fixed relative to the first pipe 1022a. In one embodiment of the invention, the second engagement device of the pipe 5054 is adapted to engage with the inner surface 5132 of the second pipe 1022b, allowing the second engagement device of the pipe 5054 to be fixed to the second pipe 1022b.

[00475] In one embodiment of the invention, the measuring sensor 5056 is located between the first pipe engaging device 5052 and the second pipe engaging device 5054, and is configured to emit a research beam of radiation. In one embodiment of the invention, one or more measuring sensor motors are operatively coupled to the measuring sensor 5056 to direct the research radiation beam along the contact surface 5136 between the pipes 1022a, 1022b. In one embodiment of the invention, the front and rear rotation motors 5030 and 5074 may be separately or collectively referred to as a "sensor motor". In one embodiment, the front and rear rotation motors 5030 and 5074 are configured to rotationally move the measurement sensor 5056 along the contact surface 5136. In one embodiment, the measurement sensor 5056 is configured to generate signals based on the profile of the contact surface 5136 between the pipes 1022a 1022b. In one embodiment, the contact surface 5136 is an annular contact surface. In one embodiment of the invention, the area of the contact surface 5136 is the inner surface of the pipes 1022a, 1022b in the area of the pipes 1022a, 1022b located near the place where the weld will be performed.

[00476] As used herein, the term "contact surface area" means the internal surfaces of the pipes to be welded in the area and, in addition, in the immediate vicinity of where the weld metal is located. The contact surface area contains at least a part or, in addition, the entire internal groove of the weld of both welded pipes, if such a groove of the weld is provided. In one embodiment of the invention, the contact surface area contains all beveled faces, and also extends beyond the beveled faces, if such beveled faces are provided.

[00477] In one embodiment of the invention, wheels 5028 on the very front section 5006 of the internal welding system are constructed and mounted to hold the clamps from seizing on the inner surfaces of the pipe. The smaller the wheel 5028 extends, the easier it is for the internal welding system to adjust to the bends of the pipe. In one embodiment, wheels 5028 may be adjustable. In one embodiment, wheels 5028 may not be adjustable. In one embodiment of the invention, spring-loaded wheels or rollers of the sole 5066 (as illustrated in FIG. 23) on the rear jaw 5144 and adjustable wheels 5276 (as illustrated in FIG. 32A) on the rear of the drive section 5008 are constructed and mounted so that the axle the clamp symmetry was lower by about 0.25 inches, the axis of symmetry of the pipe. With this configuration, when the clamps expand relative to the inner surface of the pipe, the expansion device holds the clamp over the wheels, instead of pressing the wheels against the inner walls of the pipe.

[00478] Embodiments of the invention, the “pipe engaging device” comprises a clamp that engages securely with the surface of the pipe. The clamp, for example, may contain one or more shoes, or other supporting elements, configured to reliably engage with the surface of the pipe to prevent movement of the above pipe. In another embodiment, the “pipe engaging device” comprises a seal that seals the engagement with the inner surface of the pipe so as to prevent gas from passing through it. Such a seal may contain, for example, an inflatable chamber, an elastic element or other engineering structures that engage with the inner surface of the pipe to prevent the passage of gas through it. Such a seal can be used to remove oxygen from the region of the pipe being welded in order to prevent or reduce oxidation as a result of the welding process. In yet another embodiment of the invention, the pipe engaging device comprises a combination of a clamp and a seal, or one or more clamps and / or one or more seals.

[00479] In one embodiment, the first pipe engaging device 5052 comprises a first clamp 5142 and the second pipe engaging device 5054 comprises a second clamp 5144.

[00480] In one embodiment of the invention, the first pipe engaging device 5052 comprises a first seal 5146 and the second pipe engaging device 5054 comprises a second seal 5148.

[00481] In one embodiment, the second seal 5148 and the second clip 5144 may be referred to as the rear seal 5148 and the rear clip 5144, respectively. In one embodiment, the first seal 5146 and the first clip 5142 may be referred to as front seal 5146, respectively and front clip 5142.

[00482] In one embodiment, the first pipe engaging device 5052 comprises a clamp 5142, and the second pipe engaging device 5054 comprises a clamp 5148. In one embodiment, the first pipe engaging device 5052 comprises a seal 5146, and the second pipe engaging device 5054 comprises clamp 5144.

[00483] In one embodiment, the first pipe engaging device 5052 comprises a clamp 5142 and a seal 5146, and the second pipe engaging device 5054 includes a clamp 5144 and a seal 5148. In one embodiment, the first pipe engaging device 5052 comprises a clamp 5142 and a seal 5146, and the second pipe engaging device 5054 includes a clamp 5144. In one embodiment, the first pipe engaging device 5052 includes a clamp 5142 and a seal 5146, and the second pipe engaging device 5054 includes a seal 5148. In one embodiment, the first pipe engaging device 5052 comprises a clamp 5142, and the second pipe engaging device 5054 comprises a clamp 5144 and a seal 5148. In one embodiment, the first pipe engaging device 5052 comprises a seal 5146, and the second pipe engaging device 5054 comprises clamp 5144 and seal 5148.

[00484] In the configuration, when there is a seal on one side of the measurement sensor 5056 and the control chamber 5112 and a clip on the other (opposite) side of the measurement sensor 5056 and the control chamber 5112, high pressure purge gas is directed to the region between the clip and the seal. The purge gas from the area between the clamp and the seal can leak through a small gap between the pipes to be welded, and can also exit the pipes from the side of the measuring sensor 5056 and the control chamber 5112, where there is no seal and the clamp is simply installed. Such an additional configuration prevents overpressure in the area between the clamp and the seal (for example, compared with a design having two seals, one from the side of the measuring sensor 5056 and chamber 5112), without having a regulator to adjust the pressure in the purge gas region, and / or a separate pressure relief valve in the area between the clamp and the seal. Continuous supply of purge gas under high pressure to the area between the clamp and the seal is made with the possibility of lowering the oxygen level in the area adjacent to the welding torch during the welding operation.

[00485] In another embodiment, for this reason, the first and second seals may further have openings to prevent overpressure in the purge gas chamber formed between the first and second seals. In another embodiment, one or both of the seals, when an inflatable chamber is used for sealing, may be partially filled with air to provide a predetermined or calculated clearance around them, allowing the purge region to exit at the required speed.

[00486] If two purge seals 5146 are used, 5148 inert gas is introduced into the purge chamber therebetween. However, it should be understood that purge seals 5146, 5148 do not necessarily (and usually do not) create the perfect seal. Inert gas escapes, for example, through a gap between two welded pipes 1022a, 1022b. Inert gas may also escape around seals 5146, 5148, which are not necessarily ideal. Of course, during welding operations, the gap between the pipes 1022a, 1022b is slightly closed and sealed. As a result, the pressure in the purge chamber between the pipes 1022a, 1022b can increase when creating a weld between the pipes 1022a, 1022b. For this reason, a pressure sensor inside the purge chamber is used, which detects the pressure inside the purge chamber and generates signals for one or more processors 5140, which, in turn, are transmitted to one or more valves and / or one or more controllers, controlling or regulating thus, purge gas pressure inside the purge chamber to prevent overpressure. Excessive pressure inside the purge chamber will exert more than a predetermined outward gas pressure through the gap between the pipes to be welded and can potentially change the result of the weld. In various embodiments of the invention, only individual seals 5146, 5148 are used to create a chamber that is sealed on one side only. However, this design provides for a suitable purge chamber, mostly devoid of oxygen, and also prevents the possible formation of excess pressure. In such an embodiment of the invention, an inert purge gas will escape not only through the gap between the pipes, but also through the end of the pipe, which is not sealed, and therefore a greater amount of gas may be consumed compared to the double seal embodiment.

[00487] In one embodiment, the measurement sensor 5056 and the monitoring chamber 5112 are arranged to be placed along a symmetry axis (with respect to the axis of the pipe) between the first clamp 5142 and the second clamp 5148. In other words, both the first clamp 5142 and the second clamp 5148 are located on opposite sides with respect to the axis of symmetry of the measuring sensor 5056 and the monitoring chamber 5112.

[00488] In one embodiment, the measuring sensor 5056 and the monitoring chamber 5112 are arranged to be placed along the axis of symmetry (relative to the axis of the pipe) between the first seal 5146 and the second clip 5144.

In other words, the first seal 5146 and the first clamp 5142 is located on one side of the axis of symmetry of the measuring sensor 5056 and the control chamber 5112, and the second seal 5148 is located on the other (opposite) side of the symmetry axis of the measuring sensor 5056 and the control chamber 5112.

[00493] In one embodiment of the invention, the measuring sensor 5056 and the monitoring chamber 5112 are arranged to be placed along the axis of symmetry (relative to the axis of the pipe) between the first seal 5146, the second seal 5148 and the second clip 5144.

[00494] In one embodiment of the invention, the measuring sensor 5056 and the monitoring chamber 5112 are arranged to be placed along the axis of symmetry (relative to the axis of the pipe) between the first seal 5146, the first clamp 5142 and the second clamp 5144. In other words, the first seal 5146 and the first clamp 5142 is located on one side of the axis of symmetry of the measuring sensor 5056 and the control chamber 5112, and the second seal 5144 is located on the other (opposite) side of the symmetry axis of the measuring sensor 5056 and the control chamber 5112.

[00495] In one embodiment of the invention, the measuring sensor 5056 and the monitoring chamber 5112 are arranged to be placed along the axis of symmetry (relative to the axis of the pipe) between the first clamp 5142, the second seal 5148 and the second clamp 5144. In other words, the second seal 5148 and the second clamp 5144 are located on one side of the axis of symmetry of the measuring sensor 5056 and the control chamber 5112, and the first clamp 5142 is located on the other (opposite) side of the symmetry axis of the measuring sensor 5056 and the control chamber 5112.

[00496] In one or more embodiments of the invention, since the measurement sensor 5056 is located between the clips 5142, 5144, profile data between the clips 5142, 5144 can be retrieved after the clips 5142, 5144 are locked in place. For this reason, the measuring sensor 5056 can continue scanning and detecting the profile of the area of the contact surface 5136 during the welding operation. This may be appropriate in some applications, since the area of the contact surface 5136 can be slightly changed by welding two pipes 1022a, 1022b, due to the fact that the weld itself can change the area of the contact surface 5136 in other areas that are not welded. In this regard, the measuring sensor 5056 allows you to detect and determine any changes in one or more characteristics of the area of the contact surface 5136 "on the fly" or in real time in close to the welded areas of the area of the contact surface 5136. Additionally, since the measuring sensor 5056 is located between clamps 5142, 5144, it is possible to extract preliminary profile data before welding from the area of the contact surface 5136 after applying clamping force to clamps 5142, 5144. The clamping force of clamps 5142, 5144 in itself can change the area of the contact surface 5136. For example, the clamping force can slightly change the distance between the ends of the pipe and / or the relative displacement in height between the ends of the pipe in certain (or all) areas of the contact surface 5136. Additionally, the clamping force applied by the clamps 5142, 5144 can change the correct round shape of one or both pipes (for example, the first clamp can change the correct round shape of the first pipe being welded and / or the second clamp can change the correct round shape of the second pipe oh pipe). In one embodiment of the invention, for example, the clamp shoes for any of the clamps 5142, 5144 are symmetrically and evenly distributed around the circumference around the inner surface of the engaged pipe. Additionally, the outermost surface of each clamp shoe may be equidistant from the central axis of the clamp. The distance between each clamp shoe can be set to be slightly larger than the inner diameter of the pipe. In this case, if each clamp shoe extends to its maximum position, the clamping force of the clamp 5142, 5144 is used to slightly change the deviation from the round shape of the pipe, compared with a pipe with a round shape. Until full clamping force is applied by both clamps 5142, 5144, the profile of the area of the contact surface 5136 cannot yet be completely determined, since a change in shape is possible. The measuring sensor 5136 described herein can be used to determine the profile after using the clamping of the pipe.

[00497] In one or more embodiments of the invention, since the measuring sensor 5056 and / or the monitoring chamber 5112 are located between two seals, the measuring sensor 5056 and / or the monitoring chamber 5112 can extract profile data from the gap between the seals 5146, 5148 thereafter. as seals 5146, 5148 will mesh with the inner surface 5130, 5132 of the welded pipes 1022a, 1022b. For this reason, the measuring sensor 5056 can continue to scan and detect the profile of the area of the contact surface 5136 before. during and / or after a welding operation in which the areas between the seals 5146, 5148 are provided with or filled with purge gas. This may be appropriate in some applications, since the area of the contact surface 5136 can be inspected by a measuring sensor 5056 and / or a control chamber 5112 before, during, and / or after a welding operation without breaking the seal 5146, 5148. For example, if the measuring the sensor 5056 and / or the control chamber 5112 (together with one or more processors 5140) will detect (at) that a small change in the weld is necessary or an additional welding operation is required, such a change or additional welding operation The operation can be performed without the need to install the purge chamber in another place (for example, compared with the design in which the measuring sensor and / or control chamber after welding are located outside the purge chamber and the measuring sensor 5056 and / or control chamber 5112 are introduced to check the area welded contact surface 5136 only after turning off the purge chamber). Thus, the measuring sensor 5056 can be used to scan the area of the contact surface 5136 between the pipes 1022a, 1022b to detect the profile of the area of the contact surface 5136 between the pipes 1022a, 1022b after performing the welding operation and generating profile data after welding based on scanning, and this data the profile after welding can be obtained, as well as additionally adjusted or another additional weld can be made based on the profile after welding without releasing the clamps 5142, 5144 and / or seals 5146, 5148.

[00498] In one embodiment, the clips 5142, 5144 are rotatable. In one embodiment, the clips 5142, 5144 are rotatable in different directions relative to each other.

[00499] Additionally, as described herein, the present system provides relative rotation of the first clamp and the second clamp 5142, 5144 to each other after they are fixed, respectively, on the first and second inner surface of the pipe 5130, 5132. This may be made using one or more motors for orientation 5030, 5074, controlling one or both of the clamps 5142, 5144, as described herein. Such relative rotation of the pipes 1022a, 1022b can be carried out in response to the detection by the profile data before welding that the best angular match between the ends of the pipes is available, and it can be performed by rotating the relative rotation of one or both of the clamps 5142, 5144. Such relative rotation is performed without the need to disconnect the first and second clamps 5142, 5144, while the measuring sensor 5056 remains along the axis of symmetry between the clamps 5142, 5144. After turning the first and / or second pipe 1022a, 1022b, a new profile of the region is created the contact surface 5136, and a measuring sensor 5056 is again used to scan the contact surface area 5136 to obtain the new profile information before welding. It should be understood that since it is not necessary to disconnect any of the clamps 5142, 5144 to obtain new profile data before welding, unnecessary downtime can be avoided. It should be understood that during the relative rotation of the pipes 1022a, 1022b, in one embodiment of the invention, the rollers 5332, an external platform 5330 (6010A, 6010B) can be used (according to the instructions) one or more processors 5140) to work in combination with one or more clamps 5142, 5144 to perform such a relative rotation.

[00500] In one embodiment, the clips 5142, 5144 and seals 5146, 5148 are located inside the pipes 1022a, 1022b to form an inner region / portion having a seal. In one embodiment, clamps 5142, 5144 and seals 5146, 5148 are configured to seal opposite sides of the weld.

[00501] In one embodiment, terminal 5142 and seal 5146 are activated together, and terminal 5144 and seal 5148 are also activated together. In one embodiment, the clips 5142, 5144 and seals 5146, 5148 are controlled by the same valve.

[00502] In one embodiment, seals 5146, 5148 are activated together with terminal 5142. In one embodiment, seals 5146, 5148 are activated together with terminal 5144. In one embodiment, terminal 5142 and seal 5146 are activated independently of friend, and the clamp 5144 and the seal 5148 are also activated independently of each other. In one embodiment of the invention, a separate seal control system may be configured to control the operation of both seals 5146, 5148, independently (and separately) from a clip control system configured to control the operation of both clips 5142, 5144.

[00503] In one embodiment, the clip 5144 is positioned relative to the end of the pipe 1022b. In one embodiment, then clamp 5142 and seal 5146 are activated together. In one embodiment, when the pipe 1022a is positioned relative to the pipe 1022b, the clamp 5144 and the seal 5148 are activated together.

[00504] In one embodiment, the clamps 5142, 5144 are movable between a fully extended position (as illustrated in FIG. 35B), where the clamps 5142, 5144 are not in contact with the inner surface 5130, 5132 of the pipes 1022a, 1022b and the extended position (as illustrated in Fig. 35A), where the clamps 5142, 5144 are configured to apply a clamping force to the inner surface 5130, 5132 of the pipes 1022a, 1022b. In one embodiment of the invention, the clamps 5142, 5144 are constructed and mounted to engage (contact) the pipes 1022a, 1022b and transmit forces that capture and shape the pipes 1022a, 1022b.

[00505] In one embodiment of the invention, the structure, configuration, and principle of operation of the clamps 5142, 5144 are illustrated and explained in relation to FIG. 30 and 33-42. For example, FIG. 33 and 34 illustrate a perspective and cross-sectional view of a center section 5008 of an internal welding system 5004 disposed within pipe segments 1022a, 1022b, with both clips 5142, 5144 and seals 5146, 5148 meshing with the inner surface 5130 and 5132 of the pipe segments 1022a, 1022b, and yet some components of the central section 5008 are not illustrated for clarity; FIG. 35 illustrates a view of a central section 5008 of an internal welding system 5004 placed inside pipe segments 1022a, 1022b, with only clamps 5142, 5144 (without seals) engaging with inner surface 5130 and 5132 of pipe segments 1022a, 1022b, and wherein , some components of the center section 5008 are not illustrated for clarity; FIG. 36 illustrates a perspective view of a shoe of a clamp 5157 mounted on a finger of a shoe of a clamp 5090 located in an arachnid member 5100; FIG. 37 illustrates a perspective view of an arachnid element 5100; FIG. 38 illustrates a perspective view of a finger of a shoe of a clamp 5090; and FIG. 39 and 40 illustrate a perspective view of the hub 5096 of the clamps 5142 or 5140 with the fingers of the shoe of the clamp 5090 and the levers 5092 attached thereto.

[00506] In one embodiment of the invention, as illustrated in FIG. 35C, clips 5142, 5144 are illustrated in the folded position to illustrate how the rails 5062, 5070 extend slightly higher. In FIG. 35C welding torches 5502 are illustrated in extended positions. Typically, welding torches 5502 can be in the extended position only after the clamps 5142, 5144 are in the extended position.

[00507] In one embodiment of the invention, as illustrated in FIG. 36, the welding system 5004 may comprise a plurality of first clamp shoes 5157 uniformly distributed around a circle independently of each other on their respective arachnid element 5100, and a plurality of second clamp shoes 5157 uniformly distributed around a circle independently on each other on their respective arachnid element 5100.

[00508] In one embodiment of the invention, the clamp shoes 5157 may have different heights for different pipe sizes and can be precisely adjusted, for example, using gaskets or other adjustment elements. In one embodiment, clamp shoes 5157 may be self-centering elements. In one embodiment of the invention, the clamp shoes 5157 of the internal welding system 5004 are constructed and mounted to have a radial clearance of about 1 inch with the inner surface of the pipe.

[00509] In one embodiment of the invention, each shoe of the clamp 5157 comprises elements (or surfaces) contacting the pipe surface 5156. In one embodiment, the elements 5156 contacting the surface of the pipe are constructed and mounted to engage by friction with the inner surface 5130, 5132 of pipes 1022a, 1022b on both sides of the area of the contact surface 5136 when the clips 5152, 5154 extend.

[00510] In one embodiment of the invention, as illustrated in FIG. 30 and 36-38, each shoe of the clamp 5157 is built and mounted to connect and place on a particular finger of the shoe of the clamp 5090. In one embodiment of the invention, the toe of the shoe of the clamp 5090 is constructed and mounted to extend through its corresponding hole 5158 in the arachnid element 5100. In one embodiment of the invention, the holes 5158 in the arachnoid element 5100 are built and mounted mainly for extending in the radial direction in arachnid element 5100 in such a way as to allow movement (for example, radial movement up and down) of the toe of the clip shoe 5090 in the corresponding hole 5158 in the arachnoid element 510 0. In one embodiment of the invention, the arachnid element 5100 may be any element that is built and mounted to facilitate movement of the fingers of the shoe of the clamp 5090 so that the clamps 5142, 5144 exert a pressing force on the inner surface 5130, 5132 of the pipes 1022a, 1022b.

[00511] In one embodiment of the invention, as illustrated in FIG. 38, one end 5164 of the finger of the shoe of the clamp 5090 is attached to the shoe of the clamp 5157, and the other end 5166 of the finger of the shoe of the clamp 5090 is attached to the lever 5092. In one embodiment of the invention, the end 5166 of the finger of the shoe of the clamp 5090 includes a cutout 5168 that is built and mounted for installation the lever 5092 into it. In one embodiment, the end 5166 of the finger of the shoe of the clamp 5090 also includes holes 5170 that are constructed and mounted to install fasteners 5172 for connecting the lever 5092 to the end 5166 of the finger of the shoe of the clamp 5090.

[00512] In one embodiment of the invention, as illustrated in FIG. 37, the arachnoid 5100 may include holes 5162 that are constructed and mounted to allow connection between the toe of the clip shoe 5090 and the lever 5092. In one embodiment, the apertures 5162 of the arachnoid 5100 are also constructed and mounted to allow movement of the lever 5092 when the clamps 5142, 5144 move between the folded and extended position. In one embodiment of the invention, the arachnid element 5100 is secured to a corresponding clip 5142 or 5144.

[00513] In one embodiment of the invention, the lever 5092 is an elongated element with holes made at its ends. In one embodiment of the invention, the ends of the levers typically have a rounded configuration that allows the lever 5092 to move when the clips 5142, 5144 move between their folded and extended positions.

[00514] In one embodiment of the invention, as illustrated in FIG. 30, 39 and 40, one end of the lever 5092 is connected to the finger of the clip shoe 5090, and the other end of the lever 5092 is connected to the hub 5096. In one embodiment of the invention, each clip shoe is thus connected to the hub 5096 by means of its respective finger of the clip shoe 5090 and lever 5092.

[00515] In one embodiment, the hub 5096 may include cutouts 5174 (as illustrated in FIG. 40) that are constructed and mounted to allow connections between levers 5092 and hub 5096. In one embodiment, cutouts 5174 of hub 5096 also constructed and mounted to allow movement of levers 5092 in cutouts 5174 when the clamps move between their folded and extended positions.

[00516] In one embodiment of the invention, as illustrated in FIG. 30, the clamp 5152 or 5154 comprises a cylinder 5086, a piston 5084, and a shaft 5094. In one embodiment, the piston 5084 is configured to axially move in the cylinder 5086, and the shaft 5094 holds the piston 5084. In one embodiment, the shaft 5094 moves together with the piston 5084.

[00517] In one embodiment, the hub 5096 is constructed and mounted to connect to a shaft 5094, which is longitudinally moved by a piston 5084 that reciprocates in the axial direction, for example, driven by fluid pressure (hydraulic or pneumatic) inside the cylinder 5086.

[00518] The clips 5142, 5144 are moved from the folded position (as illustrated in FIG. 35B), where the clips 5142, 5144 are not in contact with the inner surface 5130, 5132 of the pipes 1022a, 1022b to the extended position (as illustrated in FIG. 35A), in which the clamps 5142, 5144 are configured to apply a clamping force to the inner surface 5130, 5132 of the pipes 1022a, 1022b by activating the cylinder 5086 so that the piston 5084 moves axially in the cylinder 5086. In one embodiment of the invention, compressed air is from the front 5032 rotary clutch through valve en Control front clamp 5018 enters the channel 5031 (as illustrated in FIG. 30). The compressed air entering the channel 5031 presses forward on the piston 5084 to move the clamps 5142, 5144 to their extended position.

[00519] In other words, the axial movement of the piston 5084 results in the axial movement of the shaft 5094 connected to the piston 5084. In one embodiment, the axial movement of the shaft 5094, in turn, results in axial movement of the hub 5096. In one embodiment, the axial movement of the hub 5096 is converted to the radial movement of the fingers of the clamp shoe 5090 by means of their levers 5092. Thus, the radial clamping force is generated by the pressure of the compressed air fluid that drives the piston 5084, which first actuates levers 5092, transforming the axial movement of the piston 5084 (through shaft 5094 and hub 5096) into a radial movement of jaws 5157 Clogs.

[00520] In one embodiment, the cylinder size, the applied fluid pressure, and the sizes of the various components of the clamps 5142 and 5144 can be varied to control the clamping force exerted by the clamps on the inner surface 5130, 5132 of the pipes 1022a, 1022b.

[00521] In one embodiment of the invention, seals 5146, 5148 are typically toroidal or annular in shape to allow the honor of a central section (eg, front clip 5142 or rear clip 5144) to pass through them. In one embodiment of the invention, seals 5146, 5148 are constructed and mounted as radially extendable elements. In one embodiment, seals 5146, 5148 are constructed and mounted to connect to a pneumatic or hydraulic line that transports fluid to seals 5146, 5148 to fill them. Since the seals 5146, 5148 are filled, they are constructed and mounted to engage the inner surface 5130, 5132 of the pipes 1022a, 1022b, respectively forming a chamber 5150 between them. In one embodiment, after filling, seal 5146 is engaged with inner surface 5130 of pipe 1022b, and after filling, seal 5148 is engaged with internal surface 5130 of pipe 1022b. In one embodiment, after filling the seals 5146, 5148 engage on the opposite side of the contact surface 5136. In one embodiment, the chamber 5150 is a closed volume, which may be referred to as a “purge gas chamber”. In one embodiment of the invention, a chamber 5150 is constructed and mounted to receive purge gas.

[00522] In one embodiment, the internal welding system 5004 may include a purge gas container configured to provide purge gas between the filled first seal 5146 and the filled second seal 5148 to reduce the oxygen content between the first and second filled seals 5146 and 5148 during welding operation time. In one embodiment of the invention, the purge gas may be located in the drive section 5010 of the internal welding system 5004. In one embodiment of the invention, the purge gas is configured to prevent oxidation during the welding procedure. In one embodiment, the purge gas is an inert gas. In one embodiment, the purge gas may comprise argon, helium, nitrogen, or a combination thereof. In one embodiment, the purge gas comprises a combination of argon and CO ₂ .

[00523] In one embodiment, the purge gas is injected into the inner sealed region formed between the filled first and second seals 5146, 5148. By sealing the inner region from oxygen, oxidation due to exposure to very high temperatures during welding can be avoided. process.

[00524] In one embodiment, the internal welding system 5044 may include an oxygen sensor 5176 and a pressure sensor 5178. In one embodiment, the oxygen and pressure sensors 5176 and 5178 are operatively coupled to one or more processors 5140. In one embodiment of the invention , oxygen and pressure sensors 5176 and 5178 are built and mounted for placement in a rotary hub 5078. In another embodiment of the invention, oxygen and pressure sensors 5176 and 5178 are built and mounted for placement on a spider element 5100 (e.g. between clamps).

[00525] In one embodiment, the oxygen sensor 5176 is configured to measure the oxygen content in the gas of the purge chamber 5150 and send oxygen content indicative of the oxygen content in the gas of the purge chamber 5150 to one or more processors 5140. In one embodiment of the invention , one or more processors 5140 are configured to receive oxygen content data, compare the obtained oxygen content data with a predetermined oxygen content value, and enerirovat signal exceeds the oxygen content of the gas, if the data of the content of oxygen is greater than a predetermined value for the oxygen content. In one embodiment of the invention, based on a signal that the oxygen content is too high, the internal welding system 5004 may be configured to open the valve structure to allow the purge gas (from the purge gas source / tank) to enter the purge chamber 5150 until the measured oxygen content does not fall below a predetermined oxygen content. In one embodiment of the invention, based on a signal that the oxygen content is too high, the internal welding system 5004 may be configured to stop the welding procedure.

[00526] In one embodiment, the pressure sensor 5178 is configured to measure inert gas pressure in the purge chamber 5150 and send pressure data that indicate the inert gas pressure in the purge chamber 5150 to one or more processors 5140. In one embodiment of the invention, one or more processors 5140 are configured to receive pressure data, compare the obtained pressure data with a predetermined pressure value, and generate a signal if the pressure data exceed the preset pressure value. In one embodiment of the invention, based on the overpressure signal, the internal welding system 5004 may be configured to open the exhaust valve structure to release pressure in the purge chamber 5150 until the pressure drops below a predetermined pressure value.

In one embodiment of the invention, a visual signal based on such an analysis can be transmitted to the operator’s external screen. For example, a 2D camera may be a color camera, and a change in color may indicate to the operator the presence of weld defects. In one embodiment of the invention, existing changes in the profile may also indicate a weld defect.

[00534] In one embodiment of the invention, the control chamber 5112 is configured to obtain a thermal image (for example, different color regions of the metal) of the welded joint / section.

Additionally, since the measuring sensor scans the entire contact surface between the pipes, it is possible to determine the specific profile of the contact surface in each specific scanning area. This information can be used by one or more processors to control the operation of the welding torch to produce an individual / adapted weld that is adapted in accordance with a specific structural profile of the pipes being welded in the area of their contact surface.

[00541] In one embodiment of the invention, the system 5000 may comprise housings 5852, 5854 (as illustrated in FIG. 31) that are configured to receive and protect, respectively, the measurement sensor 5056 and the control chamber 5112 from flying hot sparks ( spray) from welding, and / or other fragments that can fly towards the measuring sensor 5056 and / or the control chamber 5112 during the welding operation.

[00543] In one embodiment, the pre-weld check, on-the-fly check and post-weld check can be performed by a measurement sensor 5056. In one embodiment, the pre-weld check, on-the-spot check and post-weld check can be performed by a measurement 5056 sensor and 5112 control camera.

[00544] In one embodiment, the measurement sensor 5056 may include an emitter 5180 for emitting a research beam of radiation, and a receiver 5182 for receiving measuring signals of the reflected radiation. In one embodiment of the invention, the measuring sensor 5056 emits radiation towards the area of the contact surface 5136. In one embodiment, the receiver 5182 of the measuring sensor 5136 is configured to receive radiation reflected from the surface in the area of the contact surface 5136 and generate electronic signals based thereon. . In one embodiment of the invention, the receiver or sensor 5182 of the measurement sensor 5056 is configured to receive a reflected signal to recognize a 3D topography of the weld / section. The measurement sensor 5056 may be used interchangeably in this document as "measurement laser."

[00545] In one embodiment of the invention, the measurement sensor 5136 comprises a plurality of measurement sensors that transmit radiation toward the area of the contact surface 5136. In one embodiment of the invention, each measurement sensor may include a receiver for receiving radiation reflected from the surface in the area of the contact surface 5136 and generate electronic signals based on it.

[00546] In one embodiment of the invention, the measurement sensor 5056 may include a laser displacement sensor. In one embodiment of the invention, the measuring sensor 5056 may comprise a sensor based on a complementary metal oxide semiconductor (CMOS). In one embodiment of the invention, the measurement sensor 5056 may comprise Ernostar type high definition lenses. In one embodiment of the invention, one or more processors 5140 associated with the measurement sensor 5056 is configured to use a triangle system to determine the position of the reflected light on the RS-CMOS sensor.

[00547] In one embodiment of the invention, the measuring sensor 5056 can receive incoming power from the electronic wire feed module 5046. In one embodiment of the invention, the electronic wire feed module 5046 is configured to receive incoming power from the batteries 5116 in the drive section 5010 via the rear contact rings 5080. Thus, the measuring sensor 5056 receives incoming power from the batteries 5116 in the drive section 5010 through the rear contact ring 5080 and the electronic module p wire feed 5046. This can occur when the cables, hoses and / or wires to the drive rod / halyard 5034 are disconnected from the system 5004, for example, when the system 5004 moves from one weld to the next weld.

[00548] In another embodiment, the measurement sensor 5056 can receive incoming power directly from the halyard / drive rod 5034. For example, when cables, hoses and / or wires to the drive rod / halyard 5034 are connected to the system 5004, the measurement sensor 5056 can receive incoming power directly from the halyard / drive rod 5034.

[00549] It should be understood that in some embodiments of the invention, power may be required to the sensor 5056 and / or the monitoring chamber 5112 and receiving data from them. Such power supply and / or data transmission from the measuring sensor 5056 and / or the monitoring chamber 5112 can be performed by components, for example, one or more processors 5140 and / or a power source located outside the pipe engaging device (for example, outside the clamps 5142, 5144 and / or seals 5146, 5148). In some embodiments of the invention, where power is supplied and / or data is transmitted through a wired (as opposed to wireless) communication and / or power channel, such a wired channel may take into account the rotation of the rotary hub 5078, for example, to reduce or prevent twisting and / or entanglement of the wired channel. For this reason, in one example, as described herein, a wired channel (which can transmit information and / or power) can be provided with (i) a moving part that moves with the measurement sensor 5056 when the measurement sensor 5056 directs the probe radiation along the area of the contact surface under the action of the rotational force of one or more motors for orientation, and (ii) the stationary part, which remains fixed during the movement of the moving part. The stationary and rotary parts of the wire channel can be connected by means of the described contact ring, which provides a contact surface between the movable and fixed parts to enable the transmission of signals from the moving part to the stationary part. It should be understood that either a separate wired channel (for example, with many separate wires) or a plurality of wired channels (separate channels for power supply and data exchange) can be used. Additionally, if built-in power is supplied to the measuring sensor, only the communication channel passes through the contact ring. If wireless data exchange with the measuring sensor is provided, then only the power supply channel passes through the contact ring. If the built-in power supply and wireless data exchange are provided, it is necessary to provide wired data exchange.

[00550] Similar to that described with respect to the wired communication channel, it is also necessary to provide an inert gas to the axial position between the pipe engaging devices (for example, between the clamps and / or seals) through the pneumatic channel or the inert gas line. It is also necessary to reduce the twisting and / or tangling of the pneumatic channel, which otherwise occurs when the rotary hub 5078 rotates. For this reason, the pneumatic channel must be provided with a stationary part connected to an inert gas source and a movable part that extends into the rotary hub , the movable part is connected to the stationary part by means of a rotary coupling. The rotary coupling provides relative rotation between the stationary and movable pneumatic parts.

[00551] In one embodiment of the invention, the measurement sensor 5056 is operatively coupled to a measurement sensor engine for directing the research radiation beam along the contact surface 5136 between the pipes 1022a, 1022b. In one embodiment, the measurement sensor 5056 and the measurement sensor motor may be operatively coupled to one or more processors 5140.

In one embodiment of the invention, the characteristics of the area of the contact surface 5136 may comprise different color regions of the weld metal / portion. For example, these color areas are analyzed to determine what temperature is reached in different areas of the weld / area.

[00553] In one embodiment, the measurement sensor 5056 may be configured to determine the characteristics of the area of the contact surface 5136 between the pipes 1022a, 1022b, for example, before activating the welding torch 5502 to begin fixing / welding the pipes 1022a, 1022b to each other. For example, the characteristics of the area of the contact surface 5136 may contain the geometric parameters of the groove of the pipe seam, the gap between the inner adjacent ends of the pipes 1022a, 1022b (after aligning the pipe), the gap between the grooves of the pipe seam 1022a, 1022b (after the pipe alignment), etc. one embodiment of the invention, the measuring sensor 5056 can be configured to determine the characteristics of the area of the contact surface 5136 between the pipes 1022a, 1022b, for example, 1022b, during a welding operation in the area of the contact surface before applying it to the weld metal. For example, the characteristics of the area of the contact surface 5136 may contain a difference in height between the chamfers of the pipes after they are aligned. In one embodiment of the invention, the characteristics of the area of the contact surface 5136 may contain height mismatches between adjacent pipe edges (for example, at their inner beveled edges). In one embodiment of the invention, the measuring sensor 5056 may be configured to determine the characteristics of the area of the contact surface 5136 between the pipes 1022a, 1022b, for example, after a welding operation.

[00555] In one embodiment, one or more processors 5140 are configured to interact with a measurement sensor 5056 to scan the area of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the area of the contact surface 5136 between the pipes 1022a and 1022b before the welding procedure and generation based on it profile data before welding.

[00556] As used herein, the term “profile” means a generic term for the physical attributes of a welded area of a contact surface between pipes. The term "profile data" means data corresponding to the profile that can be extracted from the area of the contact surface. For example, such data can be obtained by scanning the area of the contact surface with a measuring sensor, for example, a laser. Profile data contains various types of profile information, such various types of information are referred to as “characteristics” in this document.

[00557] In one embodiment, one or more processors 5140 are configured to interact with a measurement sensor 5056 to scan the area of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the area of the contact surface 5136 between the pipes 1022a and 1022b during the welding procedure in the area of the contact surface 5136 before applying a weld to it and generating profile data on the fly. In one embodiment of the invention, one or more processors 5140 are configured to generate signals for controlling a welding torch 5502 based on profile data obtained on the fly. Profile data obtained on the fly is described in more detail below. As used herein, the term “on the fly” also means or refers to the term “real-time mode”, meaning that the measurement or determination is used by one or more processors during the current welding operation to control the welding machine. Of course, due to the measuring sensor, the delay of the welding torch relative to the measuring sensor / measuring laser has a certain value, there is a certain buffer (or a small time delay) between receiving profile data and using such data by one or more processors to control the welding torch.

[00558] In one embodiment, one or more processors 5140 are configured to interact with a measurement sensor 5056 to scan the area of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the area of the contact surface 5136 between the pipes 1022a and 1022b after the welding procedure and generation based on the profile data after welding. The profile data obtained after welding is described in more detail below.

In one embodiment of the invention, the measurement sensor 5056 is configured to examine the weld and send a signal to one or more processors 5140 of the articulated welding head 5502 to control the movement of the welding head 5502 around the entire end joint. More specifically, the welding torch 5502 is configured to follow the measuring sensor due to the fact that the control system of the welding head continuously receives information about the profile of the weld from the end connection. Then, the information is used to continuously adjust the welding torch 5502 to achieve the desired weld structure / profile.

[00560] In one embodiment, the internal welding system 5004 may comprise a measurement sensor for each welding torch 5502. In one embodiment of the invention, the internal welding system 5004 comprises three welding torches 5502 and three associated measurement sensors 5056.

The wire of the consumable electrode 5507 is supplied from a source (eg, a reel or reel with wire) through a wire feed system 5044. In one embodiment of the invention, a welding torch 5502 is constructed and mounted to connect to a power source (eg, a DC power source). In one embodiment of the invention, an electric arc between the wire of the consumable electrode 5507 and the pipes 1022a, 1022b heats the pipes 1022a, 1022b, which causes them to melt and form a joint.

In one embodiment of the invention, the welding torch 5502 is configured to be placed on the inside inside the first pipe 1022a and / or the second pipe 1022b to perform an internal welding operation. In one embodiment of the invention, an internally positioned welding torch 5502 is mounted on (located on) and connected to a rotary sleeve 5078.

[00571] In one embodiment, the welding torch 5502 may have at least three degrees of freedom. In one embodiment of the invention, the degrees of freedom of the articulated joint allow the welding torch 5502 to be efficient and effective when filling contact surface profiles where necessary.

[00572] The degrees of freedom are generally referred to as the freedom of movement of the welding torch 5502 in three-dimensional space. Translational displacement or displacement is usually called linear displacement or displacement along the three mutually perpendicular axes X, Y and Z.

[00573] In one embodiment of the invention, as used herein, the term positioning generally means translational displacement or displacement. In one embodiment of the invention, positioning may be relative or absolute.

[00574] In one embodiment, the coordinate system may include: a Y axis located substantially parallel to the longitudinal axis AA (as illustrated in FIG. 8) of pipes 1022a, 1022b; the X axis located perpendicular to the Y axis; and an Z axis perpendicular to the Y axis and located substantially parallel to the radial axis RR (as illustrated in FIG. 8) of the pipes 1022a, 1022b. For example, translational movement along the X axis, as a rule, means moving forward and backward. Translational movement along the Y axis, as a rule, means moving left and right. Translational movement along the Z axis, as a rule, means moving up and down.

[00575] Rotational displacement or displacement typically means rotation around these three mutually perpendicular axes X, Y and Z.

[00622] Since the welding torch can oscillate during the welding operation, the gravitational forces acting on the weld pool when the welding torch rotates around a fixed tube can be taken into account. In a particular case, the angle of the welding torch may vary due to the actuation of at least one welding torch engine (i.e., the tilt motor of the welding torch 5588), depending on whether the welding torch moves upward relative to gravity or downward relative to force gravity. One or more motors (for example, a 5588 tilt torch motor) can also change the angle of the weld within the plane of rotation based on a specific location within the up or down movement of the torch. It should be understood that since the welding torch can oscillate in some embodiments of the invention, it is better that it is tilted to compensate for the force of gravity, and it is also necessary that it is not fixed, assuming that, for example, it will only move down in relation to the force of gravity. In some embodiments of the invention, as described above, the present patent application contemplates that welding may be performed by moving the welding torch up (in the opposite direction from gravity) or down (in the direction of gravity). Additionally, the welding torch may oscillate depending on different positions when turning (for example, performing a welding operation at an angle of 10 degrees from top dead center may theoretically differ slightly from the requirements when the weld is performed at 90 degrees from top dead center due to (for example) gravitational forces acting on the weld pool, as well as the tendency of the weld pool to hold differently on the inner surface of the pipe at different positions on the pipe being welded).

[00623] In one embodiment, the motors 5030 and 5074 guiding the measurement sensor 5056 also rotate the welding torch 5002 in a circumferential direction to create a weld along the contact area 5136. In one embodiment, the tilt motor 5588 controls angular oscillation of the welding torch 5502, usually within the plane of rotation. In one embodiment of the invention, the angular orientation of the welding torch 5502 is controlled based on the position of the torch. In one embodiment of the invention, the welding torch 5502 is capable of articulating rotation along the weld along the plane of rotation.

[00624] In one embodiment of the invention, the welding torch 5502 is configured so that the welding torch 5502 can have a different angle of inclination at every 90 ° rotation. For example, in one embodiment of the invention, the welding torch 5502 may have a tilt angle of 1 when performing a welding procedure within 1 sector from 2 hours to 5 hours, the welding torch 5502 may have a tilt angle of 2 when performing a welding procedure within 2 sectors of 5 hours up to 8 hours, the welding torch 5502 can have a tilt angle of 3 when performing the welding procedure within 3 sectors from 8 hours to 11 hours, and the welding torch 5502 can have a tilt angle of 4 when performing the welding procedure within 4 sectors from 11 hours to 2 hours s. In one embodiment of the invention, the welding torch 5502 is configured in such a way that the welding torch 5502 can have a different angle of inclination at each 30 ° rotation. In one embodiment of the invention, the welding torch 5502 is configured so that the welding torch 5502 can have a different angle of inclination at each rotation of 60 °. In one embodiment of the invention, the welding torch 5502 is configured so that the welding torch 5502 may have a different angle of inclination at each rotation of 120 °. In one embodiment of the invention, the welding torch 5502 is configured so that the welding torch 5502 can have a different angle of inclination when turning at any desired angle.

[00625] In one embodiment of the invention, the welding torch 5502 may be configured to have a continuously varying angle of inclination to compensate or correct a continuous change in the orientation of the welding torch relative to the direction of gravity. In one embodiment of the invention, the welding torch 5502 may be configured to translate the angle of inclination of the torch based on the position at which the welding torch is located (i.e., the position of the welding torch along the circumferential seam).

[00626] FIG. 54 illustrate a welding gun 5502 located in a normal, non-inclined position. In one embodiment of the invention, the inclined positioning system 5510 is configured to provide a welding torch 5502 angular inclination in the range +/- 5 °. For example, as shown in FIG. 55 and 56, the welding torch 5502 is moved by an inclined positioning system 5510 with an angular inclination in the range of + 5 ° so that the welding torch 5502 is located at the correct / necessary / predetermined distance from the pipe being welded. As illustrated in FIG. 57 and 58, the welding torch 5502 is moved by an inclined positioning system 5510 with an angular inclination of −5 °, respectively, so that the welding torch 5502 is positioned at the correct / necessary / predetermined distance from the pipe being welded. In one embodiment of the invention, the inclined positioning system 5510 is configured to provide a welding torch 5502 angular inclination in the range +/- 7 °. In one embodiment, the inclined positioning system 5510 is configured to provide the welding torch 5502 with an angular inclination in the range of less than +/- 5 °.

[00627] In one embodiment, the annular arc between the axial point P and the particle collision point PI (as illustrated in FIGS. 56 and 58) of the research radiation with the contact surface area remains, as a rule, constant during the welding procedure. In one embodiment, one or more processors 5140 are aware of a constant arc distance between an axial point P (e.g., a welding tip) and a probe point PI, so that one or more processors 5140 are configured to control the oscillation and rotation of the welding torch 5502 by Based on the profile verification data before welding.

[00628] This configuration of the welding torch 5502, which allows the welding torch 5502 to rotate around the axis of rotation P, makes it possible to change the angle of the welding torch 5502 during welding without affecting the speed at which the welding torch 5502 moves. For example, this is especially useful for welding systems with many welding torches. In one embodiment of the invention, a change in the angle of inclination of the welding torches will not be performed at the same time, in which case it would be advisable that the change in the angle of the torch occurs without any negative effect on the welding torches.

[00629] In one embodiment of the invention, the inclined positioning system 5510 comprises a tilt motor for the welding torch 5588, guide rails 5544, guide rollers 5546. In one embodiment of the invention, guide rails 5544 are engaged with guide rollers 5546, which facilitates inclined positioning welding torch 5502. In the illustrated embodiment, the guide rollers 5546 may comprise two upper and two lower guide rollers. In one embodiment, the inclined positioning system 5510 comprises one guide rail 5544 and four guide rollers 5546 thereof located at opposite ends of the welding torch assembly 5500.

[00630] In one embodiment of the invention, the guide rollers 5546 are constructed and mounted to connect with their respective vertical positioning elements 5538. In one embodiment of the invention, each vertical radial positioning element 5526 is configured to connect to a corresponding guide rail 5544 using any suitable mounting mechanism (e.g., fasteners 5548). This configuration allows each vertical radial positioning element 5526 to be connected to a corresponding vertical positioning element 5538 by engaging with a corresponding guide rail 5544 and guide rollers 5546.

[00631]In one embodiment, the engine 5588 is configured to (for example, mechanically coupled) rotate the gear 5590. In one embodiment, the engine 5588 is rotatable both clockwise and counterclockwise, so as to cause tilt welding torch 5502 forward or backward .. In one embodiment of the invention, the motor 5588 is configured, for example, via a gear 5590, with a guide rod 5544. In other words, the motor 5588 includes an output shaft 5592, and the gear 5590 is connected to the output shaft 5592 of the 5588 engine. By connecting 5588 engine with a guide rail 5544 by means of a gear 5590, the guide rail 5544 moves when the 5588 engine is running.

[00632] In one embodiment of the invention, the guide rail 5544 is configured to guide the upper and lower guide rollers 5546. In one embodiment, the upper and lower guide rollers 5546 are urged by the guide rail 5544 so that the upper and lower guide rollers 5546 are made with the ability to cause the movement of the vertical positioning elements 5538 (connected to the take off), thus allowing the welding torch 5502 to change its angle of inclination in the plane of movement.

[00633] In one embodiment, two opposing vertical positioning elements 5538 are connected to each other by means of an upper positioning element 5540 so that moving one of the vertical positioning elements 5538 (ie, caused by the motor 5588) results in a similar movement of the other element vertical positioning 5538. The configuration of two horizontal guide rods 5556 and 5558 connected to the upper positioning element 5540 with two ends thereof, also There is a conversion of displacement from one vertical positioning element 5538 to another.

[00634] The operation of the radial positioning system 5506 is described in more detail below. When the lead screw 5514 is rotated by the engine 5512, the screw drive nut 5516 extends along the thread. In one embodiment of the invention, the direction of movement of the screw nut 5516 depends on the direction of rotation of the lead screw 5514 by the engine 5512.

[00635] Since the screw nut 5516 is locked in the hole 5536 of the transverse radial positioning element 5524, the transverse radial positioning element 5524 is arranged to move / move the spindle 5514 along the screw transmission nut 5516. Mobile engagement between the transverse element of radial positioning 5524 and the front vertical the guide rods 5518 and 5520 also facilitate this (up and down) movement / movement of the transverse radial positioning element 5524.

[00636] In addition, since the transverse radial positioning element 5524 is connected to two vertical radial positioning elements 5526, moving (up or down) the transverse radial positioning element 5524 leads to the displacement (up or down) of two vertical radial positioning elements 5526.

[00637] Two vertical radial positioning elements 5526 are also connected to two rear radial positioning elements 5604 and 5606. Moving (up or down) two vertical radial positioning elements 5526 causes two rear radial positioning elements 5604 and 5606 to move the rear vertical guide rods 5600 and 5602. The movable engagement between the rear radial positioning elements 5604 and 5606 and the rear vertical guide rods 5600 and 5602 also contributes to There is such a movement / displacement (up and down) of two vertical radial positioning elements 5526.

[00638] As mentioned above, each vertical radial positioning element 5526 is connected to a corresponding vertical positioning element 5538 by engaging with a corresponding guide rail 5544 and guide rollers 5546. Thus, moving (up or down) of each vertical radial positioning element 5526 also leads to moving (up or down) of its corresponding vertical positioning element 5538. Since the two vertical positioning elements 5538 are rigidly are identical with the upper positioning element 5540, moving (up or down) of two elements of vertical positioning 5538 leads to moving (up or down) of the upper positioning element 5540.

[00639] Since the welding torch 5502 is connected to the upper positioning element 5540 by means of a horizontal lead screw 5552, two horizontal guide rods 5556 and 5558 and the frame of the welding torch 5564, moving (up or down) of the upper positioning element 5540 leads to movement (up or down ) of the welding torch 5502. Thus, the welding torch 5502 is installed for movement by the radial positioning system 5506 so that the welding tip 5503 is configured to move towards the welding surface of the pipes 1022a, 1022b and in the opposite direction from them.

[00640] The operation of the axial positioning system 5508 is described in more detail below. When the lead screw 5552 is rotated by the 5550 engine via a gear 5576, 5578 and 5580, the screw drive nut 5554 extends along the thread. In one embodiment of the invention, the direction of movement of the nut of the helical gear 5554 depends on the direction of rotation of the lead screw 5552 by the engine 5550.

[00641] Since the screw drive nut 5554 is locked in the hole 5568 of the welding torch frame 5564, the welding torch frame 5564 is configured to move / move (in the transverse direction) along the screw drive nut 5554. Movable engagement between the welding torch frame 5564 and the horizontal guide rods 5556 and 5558 also facilitate this movement / displacement (up or down) of the welding torch frame 5564. Movable engagement between the two horizontal guide rods 5556 and 5558 and the welding frame The 5564 torch also facilitates such movement / movement (up or down) of the frame of the welding torch 5564 (and of the welding torch 5502). In one embodiment, the axial displacement of the frame of the welding torch 5564 is limited by an elongated hole 5594 in the upper positioning element 5540.

[00642] The operation of the tilt positioning system 5510 is described in more detail below. When the gear 5590 is rotated by the engine 5588, the guide rail 5544 moves along the teeth. In one embodiment of the invention, the direction of movement of the guide rail 5544 depends on the direction of rotation of the transmission mechanism 5590 by the engine 5588.

[00643] In one embodiment, the upper and lower guide rollers 5546, pushed by the guide rail 5544, are configured to move / tilt the corresponding vertical positioning elements 5538 (connected to the guide rollers 5546).

[00644] In one embodiment, the configuration of two opposing vertical positioning elements 5538, connected to each other by the upper positioning element 5540, thus provides movement of one of the vertical positioning elements 5538 (ie, caused by the motor 5588), which leads to a similar movement of another vertical positioning element 5538. A configuration of two horizontal guide rods 5556 and 5558 connected to the upper positioning element 55 40 at its two ends also contributes to the conversion of movement from one vertical positioning element 5538 to another.

[00645] When the vertical positioning elements 5538 and the upper positioning element 5540 move / tilt (along the two horizontal guide rods 5556 and 5558), this movement allows the welding torch 5502 (connected to two horizontal guide rods 5556 and 5558 by means of the frame of the welding torch 5564) change the angle of inclination of the welding torch 5502 in the plane of movement.

[00646] As mentioned above, the welding torch is set to move in such a way that when it is moved by the tilt motor of the welding torch 5588, it rotates around the point that is on the tip of the welding torch or slightly in front of it. For example, the tip of a welding torch can oscillate around sitting in a weld pool created during welding. As a result, the position of the weld pool does not change with respect to the radius drawn to the weld pool, despite the fact that the welding torch can oscillate due to the tilt motor of the welding torch. Thus, the length of the arc between the weld pool and the point at which the emitted research beam from the test laser hits the inner surface of the pipes being welded (for example, on the contact surface area) remains constant, since the orientation motors rotate the welding torch and the test laser, despite oscillation of the welding torch by the tilt motor of the welding torch. And since speed and orientation control engines are controlled and known to one or several processors, one or more processors can control the welding parameters in a certain area of the contact surface area, knowing a fixed arc length and based on the calculation by the processor of the detected weld profile in the approaching area in front of the welding tip . In one embodiment of the invention, orientation motors are provided with angular position transducers operably coupled to one or more processors, allowing one or more processors to determine the angular position of the motors and, thus, the position of the clamps and pipes. In another embodiment of the invention, the signals from a measuring sensor (for example, a test laser) used to determine the movement of the pipes to be welded, taking into account the use of signals by one or more processors and knowing a fixed arc length, are used to control the torch at the required location corresponding to a specific position of the welding burners. In another embodiment of the invention, the point for oscillation of the welding torch does not need to be in front of or on the welding tip, and the arc length between the weld pool and the point of laser radiation entering the contact surface does not need to remain constant. Instead, one or more processors, having received information about the positioning of the welding torch tip from one or more welding torch engines and / or a measuring sensor, uses it to calculate the current position of the welding tip relative to the pipe in real time (“on the fly”) for controlling one or more welding torch engines and setting the tip of the welding torch to a predetermined position based on profile data received from the measuring sensor.

[00647] As mentioned above, the welding torch is mounted for movement or drive by one or more motors, typically in a radial direction, along the longitudinal axis of the tip of the welding torch, both towards and away from the inner surface of the pipe being welded. It should be understood that since the longitudinal axis of the welding torch (for example, through the tip of the welding torch) may not coincide with the radius of the pipe being welded (taken along the central axis) or the radius of the rotatable central hub, given the fact that the welding torch is usually directed at an angle to the front direction of the weld (and rotates due to the tilt motor of the welding torch 5588, when it comes to the "radial" movement of the welding torch and its tip towards the inner surface pipes and from it (for example, the area of the contact surface), such radial movement is used in the context described above). For example, such a radial movement of the welding torch can be considered with reference to the longitudinal movement of the welding torch along the axis of the tip of the welding torch. Since the welding torch is mounted to be moved by at least one welding torch engine, and in particular the 5512 radial welding torch engine, allowing the torch tip to move toward and away from the weld surface, the welding tip can also move from the contact surface area after each passage of the weld for surfacing of the weld material. After the first second pipe engagement device is fixed relative to the pipes, the welding torch can be used to make a full pass when welding the root of the seam, the “root” of the weld is the first weld to be applied between the ends of the pipe (for example, one 360-degree seam ) After completing the pass when welding the root of the seam, the welding tip can be slightly moved (retracted) away from the inner surface of the pipes (and, in particular, from the material of the weld deposited by the root weld) so that the second weld passage is also called “hot” the weld passage can be performed by a welding tip at a certain distance from the material of the passage when welding the root of the seam.

[00648] In one embodiment, one or more processors 5140 control motors 5030 and 5074 and one or more welding torches 5502 to generate a complete annular weld along the contact surface 5136 by rotating one or more welding torches 5502 along the contact surface 5502 in one direction of rotation until the finished circumferential weld is completed.

[00649] In one embodiment, one or more welding torches 5502 comprise a plurality of welding torches. In one embodiment of the invention, at least one of the plurality of welding torches performs a weld in the upward direction of rotation, while at least one of the plurality of welding torches performs a weld in the downward direction of rotation.

[00650] In one embodiment of the invention, the welding tip is configured to be a direction indicator of the weld. In one embodiment of the invention, the welding torch always indicates the direction of movement. In other words, the welding tip generally points in the direction of travel. In one embodiment of the invention, the angle of inclination of the welding torch is slightly larger when the welding torch 5502 performs the procedure during lifting (when the welding torch 5502 performs welding in the upward direction), and the angle of inclination of the welding torch is slightly smaller when performing the welding procedure on the run (when welding torch 5502 performs welding in the downward direction of rotation).

[00651] In one embodiment, the internal welding system is configured to perform a downhill welding procedure (that is, to weld in the downward direction of rotation) using a short arc welding procedure.

[00652] In one embodiment of the invention, when the internal welding system is configured to perform the welding procedure on the rise (that is, to perform the weld in the direction of rotation to the top), the productivity and quality of the weld can be improved. In one embodiment of the invention, the ascent welding procedure is configured to provide an option for welding both sides of the pipe at the same time, instead of the descent welding procedure performed on each side in series. For example, this may be accomplished by a plurality of welding torches and having a plurality of overlapping welds. Alternatively, the option could be 360 ° welding in one continuous run to produce a weld with only one overlap. In one embodiment of the invention, customer requirements and pipe size may determine which approach will be used.

[00653] In one embodiment of the invention, in the case where the quality requirements do not stipulate the presence of only one overlap of the weld, the weld may be performed by a plurality of welding torches installed inside the pipe. In one embodiment, the internal welding system 5004 may include four welding torches, six welding torches, or eight welding torches, with half of these welding torches welding in the downward direction, and the other half of these welding torches welding in the upward direction. In one embodiment of the invention, half of these welding torches are configured to perform the welding procedure clockwise, and the other half of these welding torches are configured to perform the welding procedure counterclockwise. In one embodiment of the invention, the four welding torches of the internal welding system 5004 can be placed 90 ° apart from each other and configured to rotate each torch 90 °. In one embodiment of the invention, six welding torches of the internal welding system 5004 may be spaced 60 ° apart and configured to rotate each torch 60 °. In one embodiment of the invention, eight welding torches of the internal welding system 5004 can be placed at intervals of 45 ° from each other and configured to rotate each 45 °. In one embodiment of the invention, the internal welding system 5004 may comprise two welding torches placed 180 ° apart from each other and configured to rotate each torch 180 °. In one embodiment of the invention, the internal welding system 5004 may include one welding torch configured to rotate 360 °.

[00654] The ability to weld in an upward and downward direction can increase the speed of a welding operation (weld run time) and also improve the quality of the weld (taking into account the influence of gravitational forces in different positions). In addition, if there are many welding torches, welding is performed both up and down at the same time (for example, many distributed around the circumference of the welding torches, moving in the same direction, while fusing the weld metal), while at least one welding torch moves up, while at least one more moves down. This is faster, for example, compared to sequential downhill welding on each side of the pipe. Alternatively, in one embodiment of the invention, a separate welding torch is used to make a 360-degree weld providing a continuous weld without overlapping sections of the weld. This overlap occurs when more than one welding torch is used and the end of each part of the weld from the follower welding torch should connect and slightly overlap the beginning of the next part of the weld weldable by the welding torch in front of the follower welding torch. As a result, for some applications, when it may be necessary to avoid overlapping the weld (which makes the weld passage less uniform at the overlap points), it is effective to use a continuous 360-degree internal weld.

[00655] In one embodiment of the invention, all welding torches indicate a forward direction of the weld. In other words, they point slightly in the direction of the weld so that the tip of the welding torch “pushes” the weld, as it were, rather than pulling it along. This is true regardless of whether the welding torch is located inside, as in some embodiments of the invention, or outside, as in other embodiments of the invention described herein. This is illustrated with respect to the internal welding machine, as illustrated in FIG. 56A. In one embodiment of the invention, the tip of the welding torch is directed at an angle Ѳ (for example, "lead") in the range from 3 degrees to 7 degrees. The lead Ѳ is defined as the angle measured between the line (radius) R from the axial center of the pipes being welded to the tip of the welding torch (or weld pool), as illustrated in FIG. 56A (line R can also be considered as a radius taken from the axial center of the rotary hub 5078 to the tip of the torch or weld pool), and a line passing through the longitudinal axis A of the tip of the welding torch. As illustrated in FIG. 56A, the welding torch rotates counterclockwise, as illustrated by arrow D. The lead Ѳ can be changed due to the operation of the tilt motor of the 5588 welding torch, as the welding torch moves the motor to circle around the inner surface of the pipes. It is assumed that the angle Ѳ will be slightly larger (for example, 6 degrees) when the welding torch moves up, and slightly smaller (for example, 4 degrees) when it moves down. Additionally, in one embodiment of the invention, the lead Ѳ can vary continuously throughout the path of a particular welding torch. In another embodiment of the invention, the pipe can be divided into sectors, while the angle of welding Ѳ varies depending on the sector. For example, when considering a full 360-degree movement or movement corresponding to the clockwise direction on the watch, the pipe can be divided into sectors: 2-5, 5-8, 8-11, 11-2. One or more engines may be controlled by one or more processors to change sector boundaries.

[00656] As will be understood from FIG. 56A, welding is performed in a counterclockwise direction in the illustrated image. For clockwise welding, one or more processors 5140 send a signal to one or more torch engines so that gear 5590 rotates and welding torch 5502 rotates (e.g., around point P) so that the axis passes through the torch (line A) moves in the opposite direction from the radial line R. For this reason, the angle θ will be negative when welding clockwise. This allows the welding torch to indicate the forward direction (“pushing” of the weld pool) when welding in a clockwise direction.

[00657] In one embodiment of the invention, as illustrated in FIG. 60A-63, internal welding system 5004 may include a WT welding torch, chamber C, and two measurement sensors L ₁ and L ₂ . In one embodiment, the WT welding torch and chamber C are 180 ° apart. In one embodiment of the invention, the angle between the chamber and the welding torch WT may vary.

[00658] In one embodiment, one or two of the measurement sensors L ₁ and L ₂ may be guiding measurement sensors that are configured to direct the WT torch during the welding procedure, as well as provide data before welding. In one embodiment of the invention, one or two measurement sensors L ₁ and L ₂ may be towing measurement sensors that are configured to tow the WT torch during the welding procedure, as well as provide data after welding.

[00659] In one embodiment, the measurement sensor L ₁ and the welding torch WT are separated by an angle of 20 °. In one embodiment of the invention, the measuring sensor L ₂ and the welding torch WT are separated by an angle of 20 °. In one embodiment, the angle between the measurement sensor L ₂ and the welding torch WT, and the angle between the measurement sensor L ₁ and the welding torch WT may vary.

[00660] In one embodiment, the angle between the measurement sensor L ₂ and the welding torch WT, and the angle between the measurement sensor L ₁ and the welding torch WT can be adjusted. For example, in one embodiment of the invention, when L ₁ is a guiding measuring sensor, the angle between the measuring sensor L ₁ and the welding torch WT is 20 ° or less, and the angle between the towing measuring sensor L ₂ and the welding torch WT is more than 20 °. In one embodiment of the invention, when L ₂ is a guiding measuring sensor, the angle between the measuring sensor L ₂ and the welding torch WT is 20 ° or less, and the angle between the towing measuring sensor L ₁ and the welding torch WT is more than 20 °.

[00661] In one embodiment of the invention, as illustrated in FIG. 60A, the measuring sensor L ₁ is located in the initial position. In one embodiment of the invention, as illustrated in FIG. 60B, the WT welding torch starts the welding procedure when the WT welding torch is located at the Start _WT point _. In one embodiment of the invention, the welding torch WT is configured to move in a clockwise direction (as indicated by arrow T ₁ ) during the welding procedure. In one embodiment of the invention, as illustrated in FIG. 61, the WT welding torch ends the welding procedure when the WT welding torch reaches the Stop _WT point _. In one embodiment of the invention, the weld bead WB _{1 is} formed by the welding torch WT when moving from the Start _WT point to the Stop _WT point in a clockwise direction indicated by the arrow T ₁ . In one embodiment of the invention, as illustrated in FIG. 60B and 61, the WT burner follows the measuring sensor L ₁ while moving from the Start _WT point to the Stop _WT point in a clockwise direction indicated by the arrow T ₁ . After the welding procedure, the welding torch WT moves counterclockwise (that is, in the opposite direction to the arrow T ₁ ) so that the measuring sensor L _{2 is} positioned back to its initial position, the Start _WT point.

[00662] In one embodiment of the invention, as illustrated in FIG. 62, the WT welding torch starts the welding procedure when the WT welding torch is located at the Start _WT point _. In one embodiment of the invention, the welding torch WT is configured to move in a counterclockwise direction (as indicated by arrow T ₂ ) during the welding procedure. In one embodiment of the invention, as illustrated in FIG. 63, the WT welding torch ends the welding procedure when the WT welding torch reaches the Stop _WT point _. In one embodiment of the invention, the weld bead WB _{2 is} formed by the welding torch WT when moving from the Start _WT point to the Stop _WT point in a counterclockwise direction indicated by the arrow T2. In one embodiment of the invention, as illustrated in FIG. 62-63, the WT burner follows the measuring sensor L ₂ while moving from the Start _WT point to the Stop _WT point in the counterclockwise direction indicated by the arrow T ₂ . After the welding procedure, the welding torch WT moves in a clockwise direction (that is, opposite to the direction of the arrow T ₂ ) so that the laser L _{1 is} positioned back to its initial position, the Start _WT point.

[00663] In one embodiment of the invention, as illustrated in FIG. 64-69, the internal welding system 5004 may include a welding torch WT ₁ and WT ₂ , a chamber C and one measuring sensor L. In one embodiment of the invention, the measuring sensor L and the welding torch WT ₁ are separated by an angle of 20 °. In one embodiment of the invention, the measuring sensor L and the welding torch WT ₂ are separated by an angle of 20 °. In one embodiment of the invention, the measurement sensor L and chamber C are separated by an angle of 180 °.

[00664] In one embodiment of the invention, as illustrated in FIG. 64, the measurement sensor L is located in the initial position. In one embodiment of the invention, as illustrated in FIG. 65, the welding torch WT ₁ starts the welding procedure when the welding torch WT ₁ is located at the start point _WT1. In one embodiment of the invention, the welding torch WT _{1 is} configured to move counterclockwise (as indicated by arrow T ₁ ) during the welding procedure.

In one embodiment of the invention, the cylinder of the drive wheel 5137 is expanded to accelerate or decelerate (move) the internal welding system 5004 in the pipes.

[00673] A portion of the compressed air received by the valve 5198 is directed to the rear rotary sleeve 5072, and the remaining portion of the compressed air received by the valve 5198 is directed to the rear clamp control valve 5062.

[00678] In one embodiment, the welding power is supplied to the internal welding system 5004 through the halyard 5034. In one embodiment, the welding power is supplied through the halyard 5034 to the welding torches 5502 through the front contact ring 5016.

[00679] In one embodiment, the batteries 5116 of the drive section 5010 are configured to supply power to all electronic modules of the internal welding system 5004, including the rear electronic module 5014, electronic wire feed module 5046, electronic module for the central section 5064 and electronic module for the drive section 5118. In one embodiment, the batteries 5116 of the drive section 5010 are configured to supply power to all electric drive motors of the internal welding system 5004, in Turning on the front rotation motor 5030, the engines of the wire feed systems 5044, the rear rotation motor 5074, the drive motors 5124, the axial motor of the welding torch 5550, the radial motor of the welding torch 5512, and the tilt motor of the welding torch 5588.

[00680] In one embodiment, battery power 5116 is directly supplied to the rear contact ring 5080, an electronic module of the center section 5064, and an electronic module of the drive section 5118. In one embodiment, battery power 5116 is supplied to the front contact ring 5016 by the rear contact ring 5080. In other words, power from the batteries 5116 is transmitted from the rear contact ring 5080 to the front contact ring 5016. In one embodiment of the invention, the electric tanie battery 5116 is supplied from the forward contact ring 5016 to the most posterior electronic module 5014 and the electronic module wire 5046.

[00681] In one embodiment of the invention, power from the batteries 5116 is supplied from the rear electronic module 5014 to the front rotation motor 5030, and from the electronic wire feed module 5046 to the motors of the wire feed systems 5044. In one embodiment of the invention, power supply from the batteries 5116 is supplied from the electronic module of the central section 5064 to the rear rotation motor 5074. In one embodiment of the invention, power from the batteries 5116 is supplied from the electronic module of the drive section 5118 to the drive motors elyam 5124. In one embodiment, power from the battery 5116 is supplied from the electronic module wire feed motor 5046 to the axial welding torch 5550, the radial engine of the welding torch 5512 and motor 5588 of inclination of the welding torch.

[00682] In one embodiment, the batteries 5116 are also configured to provide power to the monitoring chamber 5112 and the measurement sensor 5056. For example, power from the batteries 5116 is supplied from the electronic wire feed module 5046 to the monitoring chamber 5112 and the measurement sensor 5056.

[00683] In one embodiment, the batteries 5116 are also configured to provide power to the forward position sensor 5022 and the rear position sensor 5076. For example, power from the batteries 5116 is supplied from the rear electronic module 5014 to the forward position sensor 5022 and from the central electronic module sections 5064 to the rear position sensor 5076.

[00684] In one embodiment, the batteries 5116 are also configured to power the front clamp control valve 5018, the shielding gas control valve 5042, the back clamp control valve 5062, the brake valve 5190, and the drive wheel valve 5192. For example, battery power 5116 fed from the rear electronic module 5014 to the front clamp control valve 5018, from the electronic wire feed module 5046 to the shielding gas control valve 5042, from the electronic module of the central section 5064 to the rear clamp control valve 5062 and from the electronic module 5118 to the brake valve 5190, and the valve of the drive wheel 5192.

[00685] In one embodiment, the internal welding system 5004 is configured to receive and transmit communication signals via a file 5034 to an external computer system (for example, having one or more processors). In one embodiment of the invention, the received communication signals can be moved from the halyard 5034 to the rear electronic module 5014, then to the electronic wire feed module 5046 via the front contact ring 5016, then to the electronic module of the central section 5064 via the rear contact ring 5080, and then to electronic module of the drive section 5118.

[00686] In one embodiment of the invention, the communication signal can be moved (in the opposite direction to the received signal) from the electronic module of the drive section 5118, then to the electronic module of the central section 5064, then to the electronic wire feed module 5046 via the rear contact ring 5080, then, to the backmost electronic module 5014 by means of the front contact ring 5016, and to the halyard (and an external computer system having one or more processors).

[00687] In one or more embodiments of the invention described herein, and as is clear from FIG. 71, one or more processors 5140 operably coupled to a measurement sensor 5056, such as a measurement laser (or, optionally, a plurality of measurement sensors 5056, if more than one sensor is provided) via a wired communication channel or channels 5056a that transmit signals from the measurement laser 5056 to one or more processors 5140. The wired communication channel has (i) a movable portion 5056b that moves with the measurement sensor 5056 when the measurement laser directs the research beam to radiation along the contact surface area, and (ii) a stationary part 5056c that remains stationary while moving the movable part 5056b. The system further comprises the front contact ring 5016 described previously (which, on the one hand, is considered part of the wired communication channel), which provides an interface between the section of the moving part 5056b and the section of the fixed part 5056c of the communication channel, allowing signals to pass from the moving part 5056b to the fixed part 5056c .

[00688] It should be understood that the wired communication channel or channels 5056a (including its movable and fixed parts) are also configured (or, alternatively, configured to be provided if a wireless communication channel for measurement sensors 5056 is provided for to exchange data with one or more processors) to transmit electricity to the measuring sensors 5056 through the slip ring 5016.

[00689] The contact ring 5016 comprises an external stator 5016a and an internal rotor 5016b (see FIG. 26). The inner rotor 5016b and the stator 5016a have bearings 5016k between them. The stator 5016a is rigidly fixed with respect to the central frame 5068 (see Figs. 23 and 24), while the rotor 5016b is connected to the rotary hub 5078 on its central axis (for example, see Fig. 24). The rotor 5016b rotates with the rotary hub 5078 when the hub is rotated. The stator 5016a is connected to the fixed part 5056b of the wired communication channel, and the rotor 5016b is connected to the movable part 5056b of the wired communication channel, as illustrated in FIG. 26. As can be seen in FIG. 26, the rotor 5016b of the front contact ring 5016 has a hollow cylindrical configuration with a central passage 5016d through it. The passage 5016d allows other channels or lines to pass through it, in particular, for example, pneumatic channels from the front rotary clutch (for example, an external compressed air channel that will be connected to the compressed air cylinder 5128).

[00690] It is understood that a wired connection between the measurement sensor 5056 and one or more processors 5140, in some embodiments of the invention, can pass through other components. For example, as shown in FIG. 71, the communication channel from the measurement sensor 5056 may pass through the electronic components of the wire feed 5046 before it enters the contact ring 5016.

[00691] The contact ring 5016 allows the movable portion of the communication channel 5056b to move together with the rotary hub 5078, since the hub 5078 rotates during the scanning operation by the measuring sensor 5056, during scanning before welding, the contact surface area between the pipes before welding, as well as during on-the-fly scanning of the contact surface area between the pipes during the welding operation.

[00692] It should also be understood that the contact ring 5016 is further configured to connect a communication connection between one or more processors 5140 and the control camera 5112, as well as provide power to the control camera 5112. This is due to the same communication channel or channels 5056a . One or more processors 5140 are configured to receive camera data from a camera 5112 before, after, or during a welding operation. The movable part 5056b moves with the camera (and the swivel hub 5078) when the camera scans the contact area, and the fixed part 5056c remains fixed while moving the movable part 5056b, which is connected to the camera 5112.

[00693] It should further be understood that the same slip ring 5016 (and / or slip ring 5080) is configured to transmit power to other components that rotate together with the rotary sleeve 5078. For example, as illustrated in FIG. 35B, 5502k welding power supply channels for supplying welding power to the welding torches 5502, 5550k power supply and command transmission channels for controlling and supplying electricity to one or more welding torch engines 5550, 5512, 5588 controlling the operation of the welding torch - all these channels are configured to pass through a slip ring 5016. For example, for illustrative purposes, in FIG. 26 and 35B, the fixed part of the hardware power supply channel for the welding power supply channel 5502k is designated 5112c, and the movable part of the welding power supply channel is indicated as 5112b. It should be understood that, as an alternative, they can be represented by illustrating additional channels in the same slip ring 5016, or illustrated with respect to a separate slip ring.

[00694] Likewise, a 5550k hardware data channel can be provided through a slip ring 5016 for transmitting commands (and control) as well as power to the welding torch engines 5550, 5512, 5588. For clarity, to avoid redundancy, the 5550m movable part of this hardware channel 5550k is illustrated in FIG. 35B, but not illustrated in FIG. 26. It should be understood that this FIG. 26 as well as FIG. 71 are used to illustrate how the slip ring 5016 (or another slip ring) can be used to transfer power and communication data to the welding torches 5502, since the welding torches rotate with the rotary hub 5078, receiving, in fact, electricity and control commands to create weld during welding operation.

[00695] As illustrated in FIG. 35B (and several other figures), the rotary hub 5078 typically has a hollow cylindrical portion 5078a. The middle of the cylindrical part in the region, which, as a rule, is axially aligned with the welding torch, lasers and camera, has many holes or grooves 5078b passing through it. Holes 5078b allow the movable power and data channels from the contact ring 5016 (and, optionally, from the contact ring 5080) to extend radially outward from the inner part 5078c of the swivel hub 5078 to the outer part of the hub 5078 for connection between welding torches, lasers and the camera .

[00696] It should be understood that although the rotary hub 5078 is illustrated and described herein as having a cylindrical configuration, the hub may have a different shape. The swivel hub can have any tubular shape (just for example, with a rectangular or triangular section). Additionally, the pivoting hub can also be used interchangeably as the “pivoting frame”.

[00697] As illustrated and described above, the measuring sensor 5056 is mounted on the outside of the cylindrical hub, with the cylindrical hub having opposite ends and radial openings 5078b between the ends. The movable portion 5056b of the power and communication channels extends from the front contact ring 5016 and the electronic wire feed module 5046, passes through the inside of the cylindrical hub 5078c 5078c, through the radial holes 5078b, and is connected to one or more measurement sensors 5056.

[00698] As will also be understood from FIG. 24 and 35B, a shielding gas (inert gas) transport line 5032a passes through the rear rotary sleeve 5072, through holes 5080d in the slip ring, and then passes through the hollow interior 5078c of the rotary hub 5078 to one or more shielding gas valves 5042 ( see Fig. 72), while the valves are installed in the electronic wire feed module 5046 (see Fig. 71), which is mounted on the rotary hub 5078 for rotation with it. The hydraulic channel 5032a, which is a movable channel moving when the rotary hub 5078 rotates, after being connected to the shielding gas valves 5042, returns again and again passes through the hollow interior 5078c of the rotary hub 5078 (for this reason, two channels 5032a in FIG. . 24). The pneumatic channel 5032a passes through one or more holes 5078b, thereby passing in close proximity to the tip of the welding torch 5502. The pneumatic channel 5032a illustrated in FIG. 35B comprises a movable portion of a pneumatic channel that rotates when the rotary hub 5078 rotates.

[00699] FIG. 25 is a partial cross-sectional view of the front rotary clutch 5032, which, in fact, has the same design as the rear rotary clutch 5072. The front rotary clutch 5032 is used to transfer compressed air from an external source 5029 to an integrated compressed air tank 5128. The front the rotary coupling comprises a stator 5032d and a rotor 5032e. The rotor 5032e is mounted on the stator 5032d by means of ball bearings 5032f. The stator 5032d is fixed with respect to the central frame 5068, and the rotor 5032e is connected to the movable part of the pneumatic channel 5072d, the opposite ends of the movable part 5072d are connected to the rotor or the rear rotary coupling 5072. The movable part 5072d of the pneumatic channel passes through the Central passage 5016d of the contact ring 5016, such is inserted into the inner part 5078c of the swivel hub 5078 and then to the rotor of the rear rotary coupling 5072.

[00700] It should be understood that although the front contact ring 5016 is illustrated in FIG. 26 and the front rotary clutch 5032 is illustrated in FIG. 25, the same configuration for each of them applies to both the rear rotary sleeve 5072 and the rear contact ring 5080.

[00701] The method by which the movable part of the pneumatic channel passes through the central passage 5016d of the contact ring 5016 will be more clear when considering the cross section in FIG. 24, which illustrates this distinguishing feature in the context of its application to the rear slip ring 5080 and the rear rotary coupling 5072. In particular, the rear rotary coupling 5072 has an outer stator 5072a and an inner rotor 5072b. The rotor 5072b receives compressed air from the rotating pneumatic supply channel 5072d (see Figs. 24 and 70; it should be understood that Fig. 70 is a schematic diagram and channel 5072d is schematically shown in Fig. 70, but passes through the inside of the rotary hub 5078c as illustrated in Fig. 24). A rotating supply channel 5072d is connected at its opposite end to the rotor of the front rotary coupling 5032. In particular, the external supply cylinder 5029 first passes compressed air through the stator of the front rotary coupling 5032 and then discharges through the rotor of the front rotary coupling 5032. The front rotary coupling 5032 has a rotor functionally coupled to the rotary hub 5078 so as to rotate together. The rotary feed channel 5072d extends from the rotor of the front rotary coupling 5032 to the rotor 5072b of the rear rotary coupling 5072. Compressed air passes through the stator 5072a of the rear rotary coupling to the stationary pneumatic feed channel 5072f passing through it. The fixed pneumatic supply channel 5072f is connected via valves to a compressed air cylinder 5128, which periodically receives compressed air from an external supply cylinder 5029 when the cylinder 5128 is used up. As seen in FIG. 24, a rotary feed channel 5072d passes from the rotor 5072b through a central hole 5080d in the rear contact ring 5080. Then, a movable pneumatic feed channel 5072d passes through a passage 5078c inside the rotary hub 5078 to connect to the front rotary coupling 5032.

[00702] As seen in FIG. 24, the rear contact ring 5080 has an internal rotor 5080r, an external stator 5080s, and a bearing 5080m between them.

[00703] As will also be understood from FIG. 24, 72, the rear rotary sleeve 5072 also has another fixed channel 5072g that receives the shielding gas and shielding gas cylinders 5262, described in more detail below. The shielding gas flows from the stator 5072a to the rotor 5072b, and then outward from the rotor through a movable pneumatic channel 5032a. A movable pneumatic channel 5032a passes through a hole 5080d in the slip ring and in passage 5078c. The pneumatic channel 5032a moves with the rotation of the rotary hub 5078. The opposite end of the pneumatic channel 5032a is connected to the shielding gas valves 5042, and then returns (in connection with this, two channels 5032a in Fig. 24 are illustrated) and passes to the welding torches 5502. On the way to the welding torches 5502, the movable pneumatic channel 5032a passes through the holes 5078b in the rotary hub 5078, as will be understood from FIG. 72.

[00704] Although not described in detail herein, it should be understood that the supply of shielding gas through the rear rotary sleeve 5072 is also applicable to the passage of purge gas from the purge gas cylinder 7070 through the rear rotary sleeve 7072, as illustrated in FIG. . 94, described later.

[00705] In FIG. 25, the front rotary clutch 5032 is illustrated as having two inlet and outlet channels.

[00730] In one embodiment, when the characteristic value of the contact surface area 5136 is not within a predetermined range, it may be called an undesirable characteristic of the contact surface area 5136. In one embodiment, when the characteristic value of the contact surface area 5136 is not within a predetermined range, but is within a predetermined allowable / acceptable range, is determined that there is no need to correct an undesirable characteristic of the area of the contact surface 5136. In one embodiment, when the characteristic value of the area of the contact surface 5136 is not within a predetermined range and is not within a predetermined allowable / acceptable range, it is determined that there is no need to correct an undesirable characteristic of the area of the contact surface 5136.

[00731] In one embodiment, one or more processors 5140 are configured to receive electronic signals (eg, generated by a receiver of a measurement sensor 5136) to determine whether correction of an undesirable characteristic of a contact surface area 5136 is required. In one embodiment, one or more processors 5140 are configured to send commands to engines 5030, 5074 controlling the angular position relative to the axis of one of the pipes, in response to the detection of one or more unwanted characteristics of the area of the contact surface 5136, so that by means of motors 5030, 5074 cause one of the pipes 1022a, 1022b to rotate relative to the other of the pipes 1022a, 1022b to correct an undesirable characteristic. In one embodiment of the invention, motors 5030, 5074 are configured to move radial clamps 5142, 5144.

[00736] In various embodiments of the invention, the “before welding” profile data described in this application refers to data obtained from a measurement sensor (for example, using a test laser) that scanned the area of the contact surface between the two pipes to be welded before activating the welding burners to start connecting pipes to each other. This profile data is transferred to one or more processors before welding to determine if the pipes are sufficiently aligned before any weld metal is applied to the contact surface area. In one embodiment, when misalignment is detected, for example, by determining by one or more processors that the misalignment is outside the acceptable misalignment value, one or more processors are configured to send signals to platforms that interact with the outer surfaces of the pipes. One or both platforms can be adjusted based on the output signals obtained from the profile data before welding to adjust the relative positioning between the pipes to ensure an acceptable misalignment of the alignment of the interface area.

In one embodiment, the inner and / or outer clamp (s) (holding tubes 1022a, 1022b in place during the pre-weld procedure) are released before the re-alignment procedure. In one embodiment, after re-aligning the pipes 1022a, 1022b, the pipes 1022a, 1022b are clamped using external and / or internal clamps.

[00751] In one embodiment, the new pipe 1022a to be welded can rotate about its longitudinal axis with respect to the previous pipe 1022b that was welded based on the profile data before welding that were received from a measurement sensor (eg, test laser) 5056 In particular, the profile data before welding can be used to determine that in some cases the relative rotation positions of the pipes 1022a and 1022b can be changed to provide the best fit for welding. For example, if each of the pipes 1022a, 1022b has a slight roundness, then the coincidence of the pipes so that the major axis of each of the two pipes, as a rule, is aligned and the minor axis of each of the two pipes, as a rule, is aligned, can have a general positive effect . Thus, in one embodiment, the measurement sensor 5056 can generate signals that are processed by one or more processors 5140 to determine a more appropriate angular position for the incoming pipe 1022a to be welded. Such rotation can be performed by one or more processors 5140 that drive the front rotation motor 5030 to rotate the pipe 1022a before the welding operation. In particular, to rotate the incoming pipe 1022a, the central frame 5068 remains stationary in terms of rotation relative to the previously welded pipe. This fixed from the point of view of rotation between the Central frame 5068 and the pipe 1022b is due to the fact that the rear clamp 5144, actuated by one or more processors 5140, provides reliable engagement with the inner surface of the pipe 1022b to prevent mutual rotation between them. In addition to the rear jaw 5144 and the central frame 5068, which is stationary in terms of rotation relative to the pipe, the rear rotation motor 5074 is not driven by the processor 5140, while the rotation of the motor shaft is blocked. Due to the fact that the rotation of the shaft of the rear rotation motor is blocked, the entire rotary hub 5078 remains stationary from the point of view of rotation relative to the central frame 5068 and the pipe 1022b. Then, the front rotation motor 5030 is activated. Its shaft rotates to actuate the transmission mechanism, as illustrated in FIG. 19 and described above, so that the teeth of the gear 23 are rotatably engaged by the teeth of the gear 5023 of the ring gear 5021. Since the wire feed unit 5020 (which is attached to the rotary hub 5078) and the rotary hub 5078 are locked against rotation, the front rotation motor 5030 and a transmission mechanism 5023 operatively associated with it, moves in a circle along the ring gear 5021. This rotational driving force created on the front rotation motor 5030 rotates the very front section of the frame 5026, to which the engine 5030 is connected. In turn, the rotation of the front section of the frame 5026 rotates the front clamp 5142. The clamp 5142 rotates around the rotary hub 5078 on bearings 5108, 5098, which are located between the clamp 5142 and rotary hub 5078. Since the clamp 5142 is elongated and clamped on the inner surface of the pipe 1022a, as a result, the pipe 1022a rotates to a position determined by one or more processors 5140, based on the scanned information obtained th before welding from the measuring sensor 5056. During the rotation of the pipe 1022a in the case when the external platform (5330, 6010A, 6010B) engages with the external surface of the pipe, the rollers 5332 on the external platform (5330, 6010A, 6010B) are controlled using commands by one or more processors 5140 in order to additionally be in a freewheeling state in which they are passive, or additionally one or more motors functionally associated with rollers 5332 are controlled by commands through one or more processes trench 5140 for movement of the rollers 5332 at a speed commensurate (similar or the same as) the rate at which the front rotation motor 5030 provides rotation inside pipe 1022a. This latter approach creates rotational forces for the pipe 1022a both inside and outside the pipe, although in some embodiments of the invention only one driving force may be sufficient.

[00752] In the embodiment just described, the clips 5142 and 5144 mesh with respective pipes 1022a and 1022b to prevent relative rotation between the frame 5026 and the pipe 1022a and to prevent rotation between the central frame 5068 and the pipe 1022b. However, in one or more embodiments of the invention, clamps 5142 and 5144 do not have to be configured to perform this function. Instead, wheels functionally coupled to both frames can be adapted to engage with connected pipes with sufficient friction and / or external force to prevent relative rotation between the pipes and frames. In one embodiment of the invention, the impact or movement between the frames and the pipes is provided by means of the wheels, whereby it is usually possible to move longitudinally only between the frames and the pipes and the relative rotational movement between them is prevented. This may be true for wheels on one or more frames. The option of selecting the engagement of the wheels can be used only on one of the frames, on both frames and can be additionally used in combination with the clamping technique for one or both frames.

[00753] The pipe rotation methods described in this application can also be used to return the frames to the desired “initial” rotational position or “rotary” position after stopping the welding operation, with a new pipe being supplied for the next scan before welding.

[00754] In one embodiment, one or more processors 5140 are configured to send profile data before welding to a remote processor for further processing.

[00755] In one embodiment, one or more processors 5140 are configured to interact with a measurement sensor 5056 to scan the area of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the area of the contact surface 5136 between the pipes 1022a and 1022b during the welding operation in the area of the contact surface 5136 before applying a weld metal to it and generating profile data on the fly.

[00756] The on-the-fly scan / check procedure is the same for the internal welding system 3001 and the purge and test system 7001 and therefore will not be described again with reference to the joint internal welding system 3001 and the purge and test system 7001.

[00757] In various embodiments of the invention, on-the-fly profile data refers to data received from a measurement sensor during a welding operation. For example, on-the-fly profile data is obtained from a position directly in front of (in front of) the area to be welded (for example, 2.54 cm - 15.24 cm (1-6 inches) in front of the area to be welded). In particular, the measuring sensor scans the area of the contact surface within the area to be welded to provide information about the profile of the area of the contact surface immediately before applying the weld metal. It will be appreciated that the profile of the contact surface area between the pipes may vary slightly as the welding process of most of the contact surface area is performed. In other words, sequential welding itself may slightly alter the alignment / positioning of the pipes in the area of the contact surface in the areas of the contact surface to be welded. The measuring sensor measures the profile of the contact surface area immediately before the welding torch applies the weld metal in the areas of the contact surface to be welded, the signals from the measuring sensor being received and used by one or more processors to output signals / commands to the welding torch and / or its engines for control various parameters of the welding torch to adapt the welded joint to the pipes during their welding. The parameters of the welding torch may include one or more of the following: wire feed speed, wire flow rate, vibration width, mode of vibration, vibration amplitude, welding time, gas flow, arc power levels, weld current, welding voltage, weld resistance, speed the movement of the welding torch, the position of the welding tip of the welding torch along the axis of the pipe, the angular positioning of the welding tip of the welding torch relative to its plane of rotation and / or the distance from the welding tip of the welding torch to the inner surfaces of the pipes being welded.

[00758] In one embodiment of the invention, on-the-fly welding profile data may include step transition data. In one embodiment of the invention, the weld profile data during operation may include step transition data. In one embodiment of the invention, the step transition data may include a comparison between the average height difference and its corresponding predetermined value. In one embodiment of the invention, the step transition data may include deviations of the pipe height difference in all positions around the pipe perimeter based on comparison.

[00759] In one embodiment of the invention, weld profile data obtained on the fly may include weld characteristics.

In one embodiment, weld profile data obtained on the fly may include the width of the weld and the root gap of the weld.

In one embodiment, one or more processors 5140 are configured to control the position and speed of the welding torch 5502 based on profile information obtained on the fly during the welding operation. In one embodiment, the burner engine 5588 is operatively coupled to one or more processors 5140 to control the angle of the weld torch 5502 during a welding operation.

[00761] In one embodiment, one or more processors 5140 are configured to instruct one or more torch motors 5512 to move the welding tip 5503 further from the area of the contact surface 5136 after each weld pass to accommodate weld metal weld. In one embodiment of the invention, one or more processors 5140 are configured to control the axial motor of the welding torch 5550 to control the axial movement of the welding torch 5502 (i.e., move the welding tip 5503 further from the area of the contact surface 5136).

[00762] In one embodiment of the invention, one or more processors 5140 are configured to generate an initial plotted weld profile based on the state profile data before welding and to modify / adapt the initial plotted weld profile based on the profile data obtained "on the fly".

[00763] In one embodiment of the invention, the wire feed speed, the oscillation width, the welding arc power levels and / or the distance from the welding tip 5503 of the welding torch 5502 to the surfaces of the pipes to be welded can be controlled based on the profile data obtained on fly. "

[00764] In one embodiment, one or more processors 5140 are configured to interact with a measurement sensor 5056 to scan the area of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the area of the contact surface 5136 between the pipes 1022a and 1022b after the welding operation and generation on It is based on profile data after welding. In one embodiment of the invention, the state profile after welding is obtained using a measuring sensor 5056 located inside the first pipe 1022a and / or second pipe 1022b without disengaging the first pipe engaging device 5052 or the second pipe engaging device 5054, respectively, with the inner surface 5130 the first pipe 1022a or the inner surface 5132 of the second pipe 1022b.

[00765] The scanning / checking procedure after welding is the same for the lash welding system of pipeline 3001 and the purge and inspection system 7001, and therefore will not be described again with reference to the lash welding system of pipeline 3001 and the purge and inspection system 7001.

[00766] As an additional or alternative, one or more processors 5140 are configured to interact with a monitoring camera 5112, an X-ray verification device, a gamma radiation verification device, an ultrasonic monitoring device, a magnetic particle monitoring device, eddy current monitoring device, or other verification devices for scanning the area of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the area of the contact surface 5136 after the welding operation.

[00767] In one embodiment, the post-weld status profile data may include the profile (s) of the weld beads formed. In one embodiment of the invention, the post-weld status profile data may include the profile (s) of the formed passage when welding the root of the seam. In one embodiment of the invention, the post-weld condition profile data may include weld shape characteristics, such as mismatch, weakening of the weld bead, and an input angle.

[00768] In one embodiment, one or more processors 5140 are configured to instruct, based on the profile data after welding, to perform yet another welding operation in the area of contact surface 5136 between pipes 1022a, 1022b.

[00769] Some weld variables / parameters are well known for their relationships. It is understood that a change in one welding variable / parameter entails a corresponding change in another welding variable / parameter. Variables / welding parameters such as welding current, welding voltage, welding torch travel speed and heat input are interconnected. For example, if the welding current increases, and all other welding variables / parameters remain unchanged, then the voltage decreases. In addition, if the speed of movement of the welding torch increases, and all other variables / welding parameters remain unchanged, the linear energy decreases. In one embodiment, one or more processors 5140 are configured to analyze collected data (e.g., before, after, or during a welding operation) to detect problems and change process / parameters. In one embodiment, based on analysis and detection, one or more processors 5140 are configured to receive the internal welding system 5004 offline for maintenance as needed to prevent a recurrence of the situation.

[00770] In one embodiment, each data point collected / received by one or more processors 5140 before, after, or during a welding operation is compared with its corresponding (gold standard) ideal welding value. If any process variables differ by more than a set / predefined limit, these differences may be noted. If the differences exceed the maximum allowable defect volume, the welding process can be stopped so that the weld can be fixed. Over time, ideal welding values and tolerance limits can be improved as more welding data is collected.

[00771] In one embodiment, one or more processors may be configured to see what happened just before the deviation occurred and to determine if there is a defect in the programming of the control cycle that allowed the deviation to occur. In this case, one or more processors can send the updated control cycle program to the internal welding system 5004 and observe if this change improves the performance of the internal welding system 5004.

[00772] In one embodiment, the one or more processors can also be configured to monitor instructions that are given onsite by the operator of the internal welding system 5004. If these instructions are defined to prescribe welding defects, one or more processors are configured to sending a message to the operator about the termination of commands to the internal welding system 5004. If commands are defined to prevent welding defects, one or more processors are configured to send messages eniya all operators, prescribing them to begin to use these commands.

[00773] In one embodiment of the invention, one or more processors are configured to collect and analyze non-destructive testing (NDT) data. In one embodiment of the invention, locations where welding defects are detected can be compared with welding parameters that were recorded at the same location, even if the defect is small enough not to require repair. In one embodiment of the invention, one or more processors will be able to obtain information about welding defects that will not be included in a regular inspection report. This provides one or more processors with a very good statistical sample for each welding parameter and welding quality. This statistical model can be used to determine the best settings for each welding parameter, as well as the allowable deviation from the settings. These new parameters can be transferred directly to the internal welding system 5004, as each new NDT scan improves the statistical model.

[00774] In one embodiment of the invention, as described herein, computer system 5138 (comprising one or more processors 5140) may be a computer system that is local to field system 5000. In another embodiment, as described in herein, computer system 5138 may be a computer system located remotely from field system 5000 (e.g., remote computer system 13704 or another remote computer system), and may be connected to communication with the 5000 field system or its local computer system.

[00775] In one embodiment, one or more processors 5140 may receive (via a receiver) verification data associated with checking the area of the contact surface 5136 between pipes 1022a, 1022b from field system 5000 (for example, raw data from verification devices, data from 2D or 3D images, or other verification data). One or more test devices used for testing may include one or any combination of a control laser, a test chamber, an X-ray test device, a gamma radiation monitor, an ultrasonic test device, a magnetic particle monitor, a eddy current monitor, a temperature monitor or other test device. Inspection data may accordingly include one or any combination of laser inspection data, inspection chamber data, X-ray inspection data, gamma radiation inspection data, ultrasound inspection data, magnetic particle inspection data, eddy current inspection data, temperature control data or other inspection data .

[00776] In one embodiment, one or more processors 5140 may automatically generate a response containing profile data for a contact surface area 5136 (eg, pre-weld status profile data, on-the-fly profile data, post-weld status profile data, or other data ) based on the received verification data, and transmit (via the transmitter) the profile data to the field system 5000. For example, in one embodiment of the invention, when the received verification data is based on scanning the area of the contact surface before the welding operation, one or more processors 5140 can use the obtained verification data to generate a response containing the state profile data before welding for the contact surface area 5136, and transmit (via the transmitter) the state profile data before welding to the field system 5000. In one an embodiment of the invention in which the received verification data is based on scanning the area of the contact surface during the welding operation, one or more processors 5140 may use verification data to generate a response containing on-the-fly welding profile data for the area of the contact surface 5136 and transmit (via the transmitter) on-the-fly profile data to the field system 5000. In one embodiment of the invention in which the received verification data is based on scanning the area of the contact surface after the welding operation, one or more processors 5140 may use the obtained verification data to generate a response containing post-weld profile data for the contact surface area ty 5136, and transmit (through the transmitter) the profile data after welding to the field system 5000.

[00777] In one embodiment, one or more processors 5140 can automatically generate a response containing one or more welding protocols or other operating protocols based on received verification data, and transmit (via a transmitter) operation protocols as data about the operation of the control system in field system 5000. As an example, after receiving the operation protocols, the field system 5000 may perform one or more operations based on the received operation protocols. In another embodiment, one or more processors 5140 may generate profile data based on received verification data to obtain profile data for a contact surface area 5136 (for example, pre-weld status profile data, on-the-fly profile data, post-weld profile data, or others profile data). In a further embodiment of the invention, one or more processors 5140 may use the profile data to obtain welding protocols or other protocols of operations and transmission (via a transmitter) of protocols of operations to the field system 5000.

[00778] In one embodiment, one or more processors 5140 may generate a welding protocol or other operation protocol based on verification data associated with one or more other pipes (except pipes 1022a, 1022b), data associated with input parameters (eg , welding or other parameters) used to perform one or more operations (for example, welding or other operations) on other pipes, data associated with the observation of operations, or other data. By way of example, one or more processors 5140 may receive verification data from one or more field systems and analyze the verification data to determine if any pipe has defects and which of the pipes has defects. Processors can then compare one or more sets of observations of an operation performed on one or more objects that have defects found (after performing the operation) with one or more other sets of observations of the same operation performed on one or more other objects on which no defects were found to determine which circumstances likely led to the occurrence of the defect (as described in more detail elsewhere in this document). Based on such a comparison, one or more processors 5140 may generate a welding protocol or other operation protocol such that the operation protocol instructs to avoid such circumstances or otherwise prevent such circumstances (which are likely to lead to a defect) when the execution protocol operations is used for one or more subsequent operations (for example, subsequent operations that are the same or similar to the performed and observed operation).

[00779] In one embodiment, one or more processors 5140 can obtain pre-weld state profile data for the contact surface area 5136 (between tubes 1022a, 1022b) when the pre-weld state profile data is based on scanning the contact surface area 5136 in the field system 5000 before the start of the welding operation. As an example, one or more processors can receive pre-weld status profile data from the field system 5000. As another example, one or more processors 5140 can generate pre-weld status profile data based on verification data received from the field system 5000. After receiving the data, one or more processors 5136 may analyze the state profile data before welding to generate a response for the field system 5000. In one embodiment, one or more processors 5140 may equalize one or more characteristics of the state profile data before welding (for example, the characteristics of the roundedness of the pipe, the characteristics of the profile of the weld of the pipe, the characteristics of the fit of the welded joint, the characteristics of alignment and other characteristics) with one or more characteristics of acceptable predetermined state profiles before welding. Based on this comparison, processors 5140 can transmit (via a transmitter) a response in the form of data on the operation of the control system of the field system 5000, prescribing whether the field system 5000 should start the welding operation.

[00780] As an example, such a response may indicate that the area of the contact surface 5136 is within the specification for the welding operation, indicating that the field system 5000 should begin the welding operation. As an additional or alternative option, the response may contain one or more welding execution protocols for the welding operation. As another example, the answer may indicate that the area of the contact surface 5136 is not within the specification, indicating that the field system 5000 should not perform a welding operation in the area of the contact surface 5136 in its current state. In one application, the answer may indicate the need to change the area of the contact surface 5136 before the welding operation (for example, the need to rebuild the pipes 1022a, 1022b or make other changes). Thus, the answer may direct the field system 5000 to control the pipe engaging device in the field system 5000 to change the area of the contact surface 5136 before the welding operation so that the area of the contact surface 5136 is within the specification for the welding operation.

[00781] In one embodiment, one or more processors 5140 may compare one or more characteristics of the profile data (obtain them based on a scan of the area of the contact surface 5136 in the field system 5000) with one or more predefined profile characteristics to determine one or more matching characteristics. Based on matching characteristics, for example, one or more processors 5140 can automatically determine one or more welding protocols to weld a contact area 5136 between pipes 1022a, 1022b and transmit (via a transmitter) one or more welding protocols to field system 5000 to enforce field system 5000 performing a welding operation in the area of the contact surface 5136 based on one or more welding protocols. As an example, a welding protocol may contain one or more input parameters, such as wire feed speed, wire consumption, vibration width, waveform, vibration amplitude, welding time, gas consumption, welding arc power levels, welding current, welding voltage, electrical resistance during welding, the speed of movement of the welding torch, the position of the welding tip of the welding torch along the axis of the pipe, the angular positioning of the welding tip of the welding torch relative to its plane and rotation, the distance from the welding tip of the welding torch to the inner surfaces of the pipes to be welded, or other parameters.

[00782] In one embodiment, one or more processors 5140 may obtain on-the-fly profile data for the contact area 5136 (between tubes 1022a, 1022b) when the on-the-fly profile data is based on scanning areas of the contact surface 5136 in the field system 5000 during the welding operation. As an example, one or more processors 5140 can receive (via a receiver) on-the-fly profile data from the field system 5000. As another example, one or more processors 5140 can generate on-the-fly profile data based on verification data received from the field system 5000. After receiving the data, one or more processors 5140 can analyze the profile data obtained on the fly to generate a response for the field system 5000. In one embodiment of the invention, one or more process moat 5140 can compare one or more characteristics of profile data obtained on the fly (for example, pipe roundness characteristics, pipe weld profile characteristics, weld fit and alignment characteristics, weld shape characteristics, or other characteristics), with one or more characteristics of acceptable predetermined profiles (for example, predetermined pre-weld status profiles, pre-defined post-weld profiles or other profiles). Based on this comparison, processors 5140 can transmit to the field system 5000 a response containing updates to the data received on the fly with one or more welding characteristics for the welding operation. As an example, the answer may require the welding torch control to the field system 5000 based on updated on-the-fly data on welding characteristics during the welding operation.

[00783] In one embodiment, one or more processors 5140 may receive post-weld profile data for the contact surface area 5136 (between pipes 1022a, 1022b) when post-weld profile data is based on scanning the contact surface area 5136 in the field system 5000 after execution welding operations. As an example, one or more processors 5140 may receive (through a receiver) profile data after welding from the field system 5000. As another example, one or more processors 5140 may generate profile data after welding based on verification data received from the field system 5000. After for obtaining data, one or more processors 5140 can analyze the profile obtained on the fly to generate a response for the field system 5000. In one embodiment of the invention, one or more processors 5140 can compare one y or more characteristics of profile data after the welding (e.g., weld shape characteristics or other characteristics) of the one or more predetermined characteristics of acceptable profiles after welding. Based on this comparison, processors 5140 may transmit (via a transmitter) a response to the field system 5000, indicating whether the result of the welding operation is acceptable. As an additional or alternative, one or more processors 5140 can automatically determine one or more welding protocols for a subsequent operation (for example, an operation that eliminates or eliminates a defect resulting from a welding operation, an operation that usually follows a welding operation, if not a significant defect is detected, etc.) and include one or more welding protocols in the transmitted response.

[00784] As an example, if a welding operation is being performed for the root pass, the response may indicate that the root bead obtained as a result of the welding operation is within the specification, and also indicate that preparations for the subsequent welding operation for the hot pass should begin. Thus, the response may direct the field system 5000 to initiate a hot pass operation in the area of the contact surface 5136. As another example, the response may indicate that the resulting root bead is not within the specification. In one application, for example, a response may indicate that until further notice, the field system 5000 cannot continue the hot pass operation. In another application, the answer may indicate that the field system 5000 must execute a different welding protocol (different from another hot passage previously planned for the operation), when another welding protocol eliminates or levels the resulting root roller that is not within the specification .

[00785] In one embodiment, when one or more processors 5140 are local to the field system 5000 (for example, are part of a computer system local to the field system 5000), one or more processors 5140 can transmit to a remote computer system verification data associated with checking the area (for example, the area of the contact surface 5136 or another area) between the pipes 1022a, 1022b. The transmitted verification data may, for example, comprise one or any combination of the types of verification data described herein. In one embodiment, one or more processors 5140 may receive (via a receiver) a response from a remote computer system that responds to the transmission of verification data to a remote computer system (for example, a response containing pre-weld status profile data, on-the-fly profile data, profile data after welding, confirmation of transferred profile data, welding protocol or other protocol of operations, warning of a defect or other data). In one embodiment of the invention, the response may be obtained from the transmitted verification data and additional data received by the remote computer system. As an example, additional data may be associated with observations of one or more operations performed on other pipes, verification of other pipes, one or more input parameters used to perform the observed operations, or other data (described herein). Thus, for example, one or more operations in a field system (e.g., field system 5000 or another field system) can be controlled based on previously inaccessible large databases with data received from the same field system and / or other field systems. For example, databases (containing data about observing operations on other pipes, checking other pipes, input parameters for performing observed operations, or other data received from the same field system or other field systems) can be used to generate and select one or more welding protocols or other protocols for performing subsequent operations (described in this document) to prevent or reduce welding defects or to create better welds for current and future customers. As another example, an extensive database of different field systems can be used to improve validation and analysis (described in this document) to provide current and future customers with better products (for example, by reducing welding defects, detecting defects in the early stages of the process, etc.) .d.).

[00786] In one embodiment, when one or more processors 5140 are local to the field system 5000 (for example, are part of a computer system local to the field system 5000), one or more processors 5140 can transmit a contact area profile the surface 5136 between the pipes 1022a, 1022b into a remote computer system (for example, a profile obtained by scanning a region of the contact surface 5136). In response, one or more processors 5140 may receive (via a receiver) a profile confirmation of the contact surface region or a modified version of the contact surface region profile 5136 from a remote computer system. In one embodiment of the invention, one or more processors may order the welding torch of the welding system 5004 to perform welding in the area of the contact surface 5136 based on the approval or a modified version of the profile of the area of the contact surface 3136.

[00787] As an example, one or more processors 5140 of the field system 5000 may require one or more test devices to check the area of the contact surface 5136 between the pipes 1022a, 1022b to obtain test data (for example, preliminary data from the test devices, data from 2D or 3D -images, or other verification data). The verification devices used for verification may comprise one or any combination of the types of verification devices described herein. The obtained verification data may accordingly comprise one or any combination of the types of verification data described herein. As another example, one or more processors 5140 may determine the profile of the area of the contact surface 5136 based on the received verification data, but may also transmit verification data to a remote computer system for evaluating the verification data. One or more processors 5140 may transmit their specific profile of the area of the contact surface 5136 to a remote computer system to verify accuracy. Based on their own assessment of the verification data, the remote computer system can give one or more processors 5140 a response containing the approval of the profile of the contact surface area 5136, indicating that the provided profile is inaccurate, or give a different answer. As an additional or alternative option, if the provided profile is inaccurate, the remote computer system may include in response its own modified version of the profile of the contact surface area 5316, obtained based on the evaluation of verification data received from the remote computer system. In response to confirmation, for example, one or more processors 5140 may direct the welding torch of the welding system 5004 to start or continue a welding operation based on its specific profile of the contact surface 5136 to weld in the contact surface 5316. However, if a modified version of the profile is obtained, one or more processors 5140 may direct a welding torch of a welding system 5004 to initiate or continue a welding operation based on a modified profile version for product of welding in the region of the contact surface 5316.

[00788] In one embodiment, when one or more processors 5140 are local to the field system 5000 (for example, part of a computer system local to the field system 5000), one or more processors 5140 can communicate with a welding control laser system 5004 for scanning the area of the contact surface 5136 between the pipes 1022a, 1022b in order to determine the profile of the area of the contact surface 5136 before starting the welding operation and generating state profile data before welding and based on the scan. In a further embodiment of the invention, one or more processors 5140 may transmit state profile data prior to welding to a remote computer system. In response, one or more processors 5140 may receive (via a receiver) a confirmation of the state profile data before welding, or a modified version of the state profile data before welding from a remote computer system. In one embodiment of the invention, one or more processors may control the pipe engagement device 5052 and / or the pipe engagement device 5054 based on the approval or modified version of the state profile data before welding to change the area of the contact surface 5136 between the pipes before performing the welding operation.

[00789] As an example, one or more processors 5140 of the field system 5000 may require one or more test devices to check the area of the contact surface 5136 between pipes 1022a, 1022b to obtain test data before starting a welding operation in the area of the contact surface 5136. Test devices used to checks may include one or any combination of types of test devices described herein. The obtained verification data may accordingly include one or any combination of the types of verification data described herein. One or more processors 5140 may generate state profile data prior to welding based on the obtained verification data, but may also transmit verification data to a remote computer system for evaluating the verification data. One or more processors 5140 may transmit their generated status profile data prior to welding to a remote computer system to verify accuracy. Based on its own assessment of the verification data, the remote computer system can give one or more processors 5140 a response containing confirmation of the state profile data before welding, indicating that the state profile data before welding is inaccurate, or give another answer. Additionally or alternatively, if the provided state profile data before welding is inaccurate, the remote computer system may in response produce its own modified version of the state profile data before welding, obtained based on the evaluation of data received from the remote computer system. As another example, if the state profile data before welding indicates that the pipes 1022a, 1022b are offset, and the confirmation of the state profile data before welding is obtained, then one or more processors 5140 may cause the pipe engagement devices 5052, 5054 to re-align the pipes 1022a , 1022b before starting the welding operation for welding in the area of the contact surface 5136. However, if a modified version of the state profile data is obtained before welding, one or more processors 5140 can instead use a differentiated version for subsequent operations, for example, using a modified version, to determine whether re-alignment is required and how it should be performed, select the welding protocol to use to weld in the area of the contact surface 5136, etc.

[00790] In one embodiment, when one or more processors 5140 are local to the field system 5000 (for example, are part of a computer system local to the field system 5000), one or more processors can develop a welding protocol based on confirmation or a modified version of the state profile data before welding (received from a remote computer system). As an example, if confirmation of the state profile data before welding is received, one or more processors 5140 can use their generated state profile data before welding to develop a welding protocol that will be used to perform the welding operation in the area of the contact surface 5136. As another example, if a modified version of the state profile data is obtained before welding, one or more processors 5140 may use the modified version to develop a welding protocol and, which will be used to perform the welding operation in the area of the contact surface 5136.

[00791] In one embodiment, when one or more processors 5140 are local to the field system 5000 (for example, are part of a computer system local to the field system 5000), one or more processors 5140 can communicate with a control laser a welding system 5004 for scanning a region of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the region of the contact surface 5136 during the welding operation and generating profile data obtained on the fly, warping scan. In yet another embodiment of the invention, one or more processors 5140 may transmit (via a transmitter) profile data obtained on the fly to a remote computer system. In response, one or more processors 5140 may receive (via a receiver) a confirmation of the profile data received on the fly, or a modified version of the profile data received on the fly from a remote computer system. In one embodiment, one or more processors 5140 may control a welding torch of a welding system 5004 based on an approval or a modified version of on-the-fly profile data during a welding operation.

[00792] As an example, one or more processors 5140 of the field system 5000 may require one or more test devices to check the area of the contact surface 5136 between the pipes 1022a, 1022b to obtain test data during welding operations in the area of the contact surface 5136. Test devices used to checks may include one or any combination of types of test devices described herein. The obtained verification data may accordingly include one or any combination of the types of verification data described herein. One or more processors 5140 may generate profile data obtained on the fly based on the received verification data, but may also transmit verification data to a remote computer system for evaluating the verification data. One or more processors 5140 may transmit their generated on-the-fly profile data to a remote computer system to verify accuracy. Based on its own assessment of the verification data, the remote computer system can give one or more processors 5140 a response containing confirmation of the profile data received on the fly, indicating that the provided profile data received on the fly are inaccurate, or give another answer. Additionally or alternatively, if the provided state profile data after welding is inaccurate, the remote computer system may in response provide its own modified version of the on-the-fly profile data obtained based on the evaluation of the verification data performed by the remote computer system.

[00793] As another example, if confirmation of profile data obtained on the fly is received, one or more processors 5140 may use their generated profile data obtained on the fly to update the welding parameters used to control the welding torch protocol welding system 5004 (to perform a welding operation in the area of the contact surface 5136) when performing a welding operation. As another example, if a modified version of the profile data obtained on the fly is obtained, one or more processors 5140 can use the modified version to update the welding parameters used to control the welding torch protocol of the welding system 5004 (to perform a welding operation in the contact area surface 5136) when performing a welding operation.

[00794] In one embodiment, when one or more processors 5140 are local to the field system 5000 (for example, are part of a computer system local to the field system 5000), one or more processors 5140 can communicate with a control laser welding system 5004 for scanning the area of the contact surface 5136 between the pipes 1022a, 1022b to determine the profile of the area of the contact surface 5136 after the welding operation and generating profile data after welding based on the scan rations. In a further embodiment, one or more processors 5140 may transmit post-weld state profile data to a remote computer system. In response, one or more processors 5140 may receive (via a receiver) confirmation of post-weld status profile data or a modified version of post-weld status profile data from a remote computer system.

[00795] As an example, one or more processors 5140 of the field system 5000 may require one or more test devices to check the area of the contact surface 5136 between the pipes 1022a, 1022b to obtain test data after the welding operation in the area of the contact surface 5136. Test devices used to check may include one or any combination of the types of test devices described herein. The obtained verification data may accordingly include one or any combination of the types of verification data described herein. One or more processors 5140 may generate post-weld status profile data based on the received verification data, but may also transmit verification data to a remote computer system for evaluating the verification data. One or more processors 5140 may transmit their generated state profile data after welding to a remote computer system to verify accuracy. Based on its own assessment of the verification data, the remote computer system can give one or more processors 5140 a response containing confirmation of the state profile data after welding, indicating that the state profile data after welding is inaccurate, or give a different answer. As an additional or alternative, if the provided post-weld status profile data is inaccurate, the remote computer system may respond with its own modified version of the post-weld status profile data obtained based on the evaluation of the verification data performed by the remote computer system.

[00796] In one embodiment, when one or more processors 5140 are local to the field system 5000 (for example, are part of a computer system local to the field system 5000), one or more processors 5140 may be based on confirmation or a modified version of the state profile data after welding (obtained from a remote computer system) to prescribe another welding operation in the area of the contact surface 5136 between the pipes. As an example, if confirmation of the state profile data after welding is received, one or more processors 5140 can use their generated state profile data after welding to determine whether the result of the welding operation has one or more defects, and if the contact surface area 5136 is ready for the next step operations, or for other definitions. In one application, for example, after the root pass operation is completed in the area of the contact surface 5316, the state profile data after welding the root pass layer in the area of the contact surface 5316 may reveal that the root pass layer is not thick enough. In response, the state profile data after welding can be used to determine the welding parameters for the welding operation to compensate for insufficient thickness or the welding parameters for the hot passage operation to create a hot passage layer (on the root passage layer) that compensates for the insufficient thickness of the root passage layer. As another example, if a modified version of the state profile data is obtained before welding, one or more processors 5140 may use the modified version to execute the above instead of their generated state profile data after welding.

[00797] In one embodiment of the invention, welding parameters that affect welding quality may include voltage, current, welding torch travel speed, wire feed speed, gas flow, etc. In one embodiment, other welding parameters that affect the quality of the welding may include resistance, temperature, etc.

[00798] In one embodiment, the voltage used in the welding process can affect the width of the weld bead and the shape of the weld bead. In one embodiment of the invention, the voltage is measured in volts. In one embodiment of the invention, the welding system may include a voltage sensor configured to measure the voltage of the power source used to create the welding arc.

[00799] In one embodiment, the current used in the welding process can affect the penetration of the weld bead. In one embodiment of the invention, the current is measured in amperes. In one embodiment of the invention, the welding system may include a current sensor configured to measure the current of the power source used to create the welding arc.

[00800] In one embodiment of the invention, the welding feed rate is the movement speed of the welding electrode during welding along the weld joint. In one embodiment of the invention, the welding electrode is supplied from a welding torch. In one embodiment of the invention, the welding speed can be controlled by controlling a welding torch that feeds the welding electrode. In one embodiment of the invention, the welding speed during the welding process may affect the size of the weld bead and / or the penetration of the weld bead. In one embodiment of the invention, the welding speed is measured in millimeters / second or in inches / minute.

[00801] In one embodiment, the wire feed rate / wire use is the speed at which the material of the welding electrode is used (or fed into the weld) during the welding process. In one embodiment of the invention, the wire feed speed is measured in millimeters / second or in inches / minute. In one embodiment of the invention, the welding system may include a wire feed speed sensor that is configured to measure the material flow of the welding electrode.

[00802] In one embodiment of the invention, the rate of change of coil mass allows the welding system to measure the speed at which welding wire 5007 is fed into the weld. In one embodiment of the invention, the feed motor operates at a predetermined / predetermined speed, but the wheel that pushes the wire 5007 may slip due to minor changes in the wire 5007 or due to wear on the feed wheel itself. These slippages may be temporary and their presence may be recorded and used in a quality control feedback loop. If slippage is constant, one or more 5140 processors may be configured to increase the speed of the feed motor to compensate for it. Over time, the overdrive ratio can be increased. In the end, compensation will become impossible and the 5004 welding system will be decommissioned for maintenance. In one embodiment of the invention, monitoring the increase in the upshift ratio across all welding systems allows one or more processors to determine the best limit for the maximum allowable upshift ratio. Then this setting can be transferred to all welding systems in operation. In one embodiment of the invention, one or more processors 5140 may be configured to update the value at any time as data becomes available to minimize technological interruptions and minimize downtime of the mechanism for maintenance purposes.

[00803] In one embodiment, the welding system may include a gas flow sensor configured to detect / detect the flow rate of the shielding gases used in the welding procedure. In one embodiment, the shielding gas may be an active gas, which is configured to protect the molten weld pool. In one embodiment, the gas flow sensor is configured to provide a signal proportional to the gas flow rate in the shielding gas pipeline. In one embodiment of the invention, one or more processors 5140 of the field system 5000 are configured to stop welding when the shielding gas flow rate is outside a predetermined gas flow rate range.

[00804] In one embodiment, the pipes are preheated before starting the welding process. In one embodiment of the invention, the temperature of the pipes can be monitored by one or more temperature sensors of the welding system. In one embodiment of the invention, one or more temperature sensors are configured to measure pipe temperature at each point of the entire weld length. In one embodiment, one or more processors 5140 of the field system 5000 are configured to stop the welding process when pipe temperatures are not within a predetermined temperature range.

[00805] In one embodiment of the invention, the welding system may include a resistance sensor configured to detect / detect the input electrical resistance of the welding system.

[00806] In one embodiment, the correct wire / welding electrode / filler must be used for each welding pass. For example, the only difference between two coils of wire is a difference in wire diameter of 0.1 millimeters. If the manufacturer’s label for the wire spool has been smeared or faded, the wrong spool may be loaded into the welding system. The RFID tag on the coil contains the identifier of the coil. In one embodiment of the invention, the RFID tag on the coil can be read by a sensor in the welding system. In the case where the RFID tag contains the wrong coil identifier, the welding system is configured to not supply wire material and warn the user about the need to replace with the corresponding wire.

[00807] In one embodiment of the invention, the weight of the coil can be controlled by one or more processors 5140 of the field system 5000. If the welding wire ends during welding, the voltage signal that the processor uses to control the distance between the welding tip and the work area goes to zero. In response, the processor moves the tip closer to the work area, which causes the tip to touch the molten metal of the weld and cause a defect in the inclusion of copper. Therefore, information about the exact weight of the wire remaining on the reel helps the welding system to prevent the start of the welding pass, which requires more welding wire than is available. In addition, if the weight of the spool no longer changes, this may indicate an empty spool or failure of the wire feed mechanism. In any case, one or more processors 5140 of the field system 5000 are configured to stop the welding process.

[00808] In one embodiment, one or more processors 5140 of the field system 5000 are configured to track the mass of each coil in real time. Each welding pass in a welded joint requires a different amount of wire due to a change in diameter and a change in the width of the fill groove of the weld.

[00809] If one or more processors 5140 of the field system 5000 determines that there is very little wire left in the coil to complete the next welding pass, but there will be enough wire in it to complete another welding pass, one or more processors 5140 of the field system 5000 may be configured to inform the operator of the need to remove the coil and transfer it to another operator. For example, a coil starts with 10 pounds of wire, and 1.3 pounds of wire is required for a weld run by the welding system. The welding system will be able to complete its weld passes on 7 welded joints before very little wire remains in the coil.

[00810] When the coil is removed after passing the 7th weld pass, 0.9 pounds of wire will remain in that coil, which will be wasted. If there is another welding pass that requires, for example, 1.1 pounds of wire, then one or more processors 5140 of the field system 5000 are configured to alert the operator to remove the coil after 6 welding passes. In this case, the coil will still contain 2.2 pounds of wire. Then this coil can be used for a weld passage, which requires only 1.1 pounds of wire to complete 2 such welding passes (without wasting wire).

[00811] In one embodiment, the welding wire 5507 passes through the welding tip 5503. The welding tip 5503 also has a high welding current. Both of these factors lead to wear of the welding tip 5503. In this case, the contact point inside shifts, which inherently affects the characteristics of the arc and, therefore, the quality of welding. In one embodiment of the invention, welding parameters, such as voltage, current, wire feed, power and resistance, are monitored in real time. This data is sent to the tablet via one or more processors and must be analyzed to compare signatures for the above variables due to the intense computational nature of the analysis. When analysis reveals an unavoidable problem, a message is sent to the internal welding system 5004 and the operator to replace the welding tip 5503 before starting the next welding. In addition, this data can be used in a quality control feedback loop. In one embodiment of the invention, the results obtained from the quality control feedback loop can be used to update the welding tip wear signatures on the fly.

[00812] In one embodiment, exemplary welding parameters that are used in uphill and downhill welding processes are illustrated in FIG. 72D. For example, in one embodiment of the invention, at least one of the plurality of welding torches 5502 welds in the upward rotation direction (i.e., up), while at least one of the plurality of welding torches 5502 welds in the downward rotation direction (i.e., at descent). In one embodiment of the invention, the welding parameters shown in this document are given as an example and are in no way optimized and do not include anything that may require changes during these welding processes. In one embodiment of the invention, the travel speed for performing welding on the run is 13.5 inches / minute, and for performing welding on the rise is 10.0 inches / minute. In one embodiment of the invention, the amplitude of the transverse vibrations of the electrode is 0.09 inches for the descent welding process and 0.15 inches for the ascent welding process. In one embodiment, the oscillation speed is 160 beats per minute for the downhill welding process and 130 beats per minute for the uphill welding process. In one embodiment, the wave control 1 (i.e., associated with the wire feed speed) is 400 for the downhill welding process compared to 370 for the downhill welding process. In one embodiment of the invention, the welding passages were welded at 16.5 V with a voltage controlled power source.

[00813] The following describes the operation of the internal welding system 5004. In one embodiment of the invention, the internal welding system 5004 is operable through a repeating cycle of operation.

[00814] After it is determined that welding of the current welding joint is completed, one or more processors 5140 are configured to send communication signals to the electronic wire feed module 5046 for controlling (via control signals) the welding torch engines 5512, 5550, 5588 (by) for return welding torches 5502 to their original, retracted position. One or more processors 5140 is also configured to send communication signals to the front electronic module 5014 to control / disable (via control signals) the front clamp control valve 5018 to retract the first engagement device 5052 to its original, retracted position and send the communication signal to the central electronic module sections 5064 for control / shutdown (by means of control signals) of the control valve of the rear clamp 5062 to remove the second gearing device 5054 in its original, removed th position. Internal welding system 5004 (containing welding torches 5502 and clamps 5144, 5142) should be moved to the next weld joint.

[00815] In one embodiment, one or more processors 5140 are configured to transmit communication signals to an electronic module of a drive section 5118 to control (via control signals) drive motors 5124 to accelerate the internal welding system 5004 to move it at a given speed, and also subsequent deceleration and stopping at the next welded joint. In one embodiment, the target speed at which the internal welding system 5004 is accelerated may be 6 feet / second.

[00816] When the second engagement device 5054 is located on the next weld joint, the electronic module of the drive section 5118 sends communication signals to the electronic wire feed module 5046 to check alignment with the end of the pipe. In one embodiment, the electronic wire feed module 5046 is configured to control one or more measurement sensors 5056 to measure where exactly the second engagement device 5054 is relative to the end of the pipe. In one embodiment, the swivel hub 5072 may not work when one or more of the measurement sensors 5056 measure where exactly the second engagement device 5054 is relative to the end of the pipe.

[00817] In one embodiment, the electronic wire feed module 5046 is configured to send measured distance data to the electronic module of the drive section 5118. In one embodiment of the invention, the electronic module of the drive section 5118 is configured to control (via control signals) drive motors 5124 for moving the first and second engagement devices 5052, 5054 based on the measured distance data.

[00818] In one embodiment, when the second engagement device 5054 is properly aligned and located relative to the end of the pipe, the electronic module of the drive section 5118 is configured to transmit communication signals to the electronic module of the central section 5064 that the internal welding system 5004 is in proper position on the next welded joint. In one embodiment of the invention, the electronic module of the central section 5064 controls (opens by means of control signals) a back clamp control valve 5062 to lift the second engagement device 5054 and to capture the old / existing pipe.

[00819] Next, the next / new pipe segment 1002a is inserted by the work crew and pushed onto the frontmost section 5006 of the internal welding system 5004 to the desired position. At this time, one or more processors 5140 are configured to transmit communication signals to an electronic wire feed module 5046 to control one or more measurement sensors 5056 to verify pipe alignment. In one embodiment of the invention, one or more processors 5140 may rotate the rotary hub 5078 to measure at multiple locations.

[00820] If the pipe alignment data is within the specified tolerance, the electronic wire feed module 5046 sends communication signals to the front-most electronic module 5014 to actuate the front clip 5142. In one embodiment, the front-most electronic module 5014 monitors / opens (via control signals) a front clamp control valve 5018 for lifting the first engagement device 5052 and capturing a new pipe segment 1002a.

[00821] If the pipe alignment data is not within the specified tolerance, the electronic wire feed module 5046 sends one or more processors 5140 communication signals (message) identifying misalignment between the pipes 1022a, 1022b. In one embodiment of the invention, this information can be transmitted to the crane operator by conventional manual signals from the crane operator or by an electronic signal to a computer display terminal in the crane cabin.

[00822] After the pipes are clamped, one or more processors 5140 are configured to send communication signals to the electronic wire feed module 5046 to control one or more measurement sensors 5056 to measure the clearance and radial displacement of the step transition at several points along the circumference of the welded joint. In one embodiment of the invention, this data is communicated to one or more processors 5140 and compared with tolerances.

[00823] If the assembly of the weld joint (that is, the gap and the radial displacement of the stepped transition) is within the specified tolerance, either one or more processors 5140 or the electronic wire feed module 5046 sends communication signals to the operator indicating that welding can be started, or sends communication signals to the 5046 electronic wire feed module to automatically start the welding process.

[00824] If the assembly of the weld joint (that is, the gap and the radial displacement of the step transition) is not within the specified tolerance, a warning is sent to the operator and he can restart the clamp sequence or turn off the warning. In one embodiment, the internal welding system 5004 is configured to weld up to 4 millimeters of clearance and radial displacement of the stepped transition.

[00825] In one embodiment, the electronic wire feed module 5046 is configured to automatically start a welding process. In one embodiment, one or more processors 5140 are configured to send communication signals through the halyard 5034 to a welding power source to include a welding power source for welding torch (s) 5502. In one embodiment, the electronic wire feed module 5046 configured to control / move one or more welding torches 5502 in the radial, axial and / or angular direction to the appropriate position for welding. In one embodiment, an electronic wire feed module 5046 moves one or more welding torches 5502 in the radial, axial, and / or angular direction by an appropriate working distance from the pipe and to the center of the weld, measured by one or more sensors 5056.

[00826] In one embodiment, the electronic wire feed module 5046 is also configured to control (turn on) the shield gas valve (s) 5042 to supply shield gas to the welding torch (s) 5502 and control the engines of the welding feed system 5044 for start feeding the welding wire or electrode to the welding torch (s) 5502.

[00827] In one embodiment, the electronic wire feed module 5046 sends communication signals to both the electronic module of the front section 5014 and the electronic module of the center section 5064 to start rotation of the rotary hub 5078. In one embodiment, the electronic wire feed module 5046 sends communication signals to both the electronic module of the front section 5014 and the electronic module of the central section 5064 to synchronize the front rotation motor 5030 and the rear rotation motor 5074. In one In an embodiment of the invention, the electronic module of the front section 5014 itself sends control signals to control the front rotation motor 5030, and the electronic module of the central section 5064 sends control signals to control the rear rotation motor 5074. The front rotation motor 5030 and the rear rotation motor 5074 are rotatable hubs 5078, the front and rear clips 5142, 5144 being stationary. In one embodiment, the swivel hub 5078 continues to rotate to the full extent of the weld.

[00828] In one embodiment, the electronic wire feed module 5046 is configured to control one or more measurement sensors 5056 to locate the center of the weld joint and move the welding torch 5502 in the axial direction to the weld joint.

[00829] In one embodiment, the electronic wire feed module 5046 is configured to measure welding power voltage. The measured voltage data can be used by the electronic wire feed module 5046 to determine the distance from the welding torch 5502 to the pipe. In one embodiment, the electronic wire feed module 5046 is configured to radially adjust the welding torch 5502 to maintain a constant distance from the welding torch 5502 to the pipe. In one embodiment of the invention, the electronic wire feed module 5046 may oscillate the welding torch 5502 in the axial direction to improve welding quality.

[00830] In one embodiment, the electronic wire feed module 5046 is configured to change the angle of the welding torch 5502 based on which portion of the welded joint is being welded. For example, the angle of inclination of the welding torch 5502 in the displacement plane is adjusted to compensate for gravity.

[00831] In one embodiment, the electronic wire feed module 5046 can be configured to change the wire feed speed or send communication signals to a welding power source (via a halyard 5034) to change the welding current based on measurement data from one or more measuring sensors 5056.

[00832] In one embodiment of the invention, the welding process can be performed by one welding torch in one welding passage with a rotation of 360 ^about . In one embodiment of the invention, welding may begin and end anywhere along the weld.

[00833] In one embodiment, the welding process may be performed using N equidistant welding torches 5502 when the swivel hub 5078 rotates (360 / N) degrees to complete one welding pass. In one embodiment of the invention, the welding process can be performed using N equidistant welding torches 5502 when the rotary hub 5078 is rotated (2 times (360 / N)) degrees to complete two welding passes. For example, in one embodiment, when the internal welding system 5004 comprises three equidistant welding torch 5502, 5078 rotary hub rotates by ¹²⁰ for performing one welding pass and rotated 240 ^about to perform two welding passes.

[00834] When the welding torches 5502 reach the point at which the previous welding torch 5502 began its welding pass, one or more measurement sensors 5056 detect an existing weld bead, and the electronic wire feed module 5046 is configured to move the welding torches 5502 in the radial direction for alignment.

[00835] In one embodiment of the invention, two welding passes can be performed as described above, with a slight stop between the welding passes to provide complete laser and visual inspection of the state after welding. In one embodiment, welding can be performed at ^about 360 using N unevenly remote burners 5502, each welding torch 5502 performs subsequent weld pass to reach the total number N of welding passes at ^about 360 plus the distance from the first burner to N-th of the burner.

[00836] After it is determined that the welding is completed, one or more processors 5140 are configured to send communication signals to the electronic wire feed module 5046 for controlling (via control signals) the welding torch engines 5512, 5550, 5588 (by) to return the welding torches 5502 in their original, retracted position. For example, welding torches 5502 can be retracted back to their starting positions for each axis (radial, axial, inclined).

[00837] In one embodiment, the swivel hub 5078 continues to rotate while the electronic wire feed module 5046 controls one or more gauges 5056 and one 2D camera 5112 to check weld quality. In one embodiment of the invention, if certain types of welding defects are detected (e.g., filler loosening, insufficient weld reinforcement), one or more processors 5140 are configured to send communication signals to the electronic wire feed module 5046 to move the welding torch 5502 to this location and apply additional material to eliminate the defect.

[00838] After the inspection and any repairs are completed and confirmed by the operator, the operator can send communication signals to the very front electronic module 5014 to control / deactivate (via control signals) the control valve of the front clip 5018 to draw the first engagement device 5052 into it the initial retracted position and sending communication signals to the electronic module of the central section 5064 for controlling / deactivating (via control signals) the back clamp control valve 5062 to retract the second device Lenia 5054 to its initial retracted position.

[00839] In submarine applications, errors in both angular and positional alignment of the pipes can be corrected by sending control signals from one or more processors 5140 to platforms 5330 or platforms 6010A and 6010B (to control linked rollers 5332).

[00840] In one embodiment of the invention, the purge and inspection system 7001 or internal welding system 5004 may include one clamp that is designed and configured to grip the inner surface of the first pipe 1022b. In one embodiment, platforms 5330 or platforms 6010A and 6010B are configured to move the second / inlet pipe 1022a to a desired position. In one embodiment, one or more processors 7062 or 5140 are configured to interact with a measurement sensor 5056 or 7042 to verify alignment between the pipes and transmit control signals to platforms 5330 or platforms 6010A and 6010B to correct any pipe alignment errors (angular or positional). In one embodiment of the invention, the control signals from one or more processors 5140 are configured to adjust the relative position between the pipes (correct errors of their alignment). In one embodiment of the invention, this process can be applied to pipes with thin or thick walls, which have a very low (<20) ratio of diameter to wall thickness, since no clamping force will noticeably change the shape of the pipe with low D / t.

[00841] In one embodiment of the invention, the purge and inspection system 7001 or the internal welding system 5004 may include two clamps. For example, one clamp is designed and configured to grip the inner surface of the first pipe 1022b. In one embodiment, platforms 5330 or platforms 6010A and 6010B are configured to move the second / inlet pipe 1022a to a desired position. In one embodiment, the second clamp is designed and configured to grip the inner surface of the second / inlet pipe 1022a. In one embodiment, one or more processors 7062 or 5140 are configured to interact with a measurement sensor 5056 or 7042 to verify alignment between the pipes. For example, if alignment is not acceptable, the second clamp releases the second pipe 1022a. One or more processors 7062 or 5140 are configured to send control signals to platforms 5330 or platforms 6010A and 6010B to correct any pipe alignment errors (angular or positional). In one embodiment of the invention, the control signals from one or more processors 5140 are configured to adjust relative positioning between the pipes (correct errors of alignment), for example, by changing the position of the pipe 1022a. This process can continue until acceptable pipe alignment is achieved using the measuring sensor or a predetermined number of attempts (e.g. 10), at which time the second pipe 1022a is removed and a new second pipe is moved in its place.

[00842] In one embodiment of the invention, crane and clamp alignment is used in the alignment and welding process of the onshore pipeline. In surface applications of the pipeline, the error of the angular alignment of the pipeline can be corrected by giving commands to the crane operator, and the error of the positional alignment can be corrected by giving commands to the workers to install the gasket between the clamp and the pipe.

[00843] In one embodiment of the invention, the purge and inspection system 7001 or the internal welding system 5004 may include one clamp that is designed and configured to grip the inner surface of the first pipe 1022b. In one embodiment of the invention, the crane operator moves the second / inlet pipe 1022a to the desired position, and workers apply an outer clip around the joint. In one embodiment, one or more processors 7062 or 5140 are configured to interact with a measurement sensor 5056 or 7042 to verify alignment between the pipes. If the measuring sensor 5056 or 7042 detects an error in the angular displacement / alignment of the pipe, the crane operator sends commands to correct the error of the angular displacement / alignment of the pipe, and workers release the clamp while moving the pipe. If the measuring sensor 5056 or 7042 detects a misalignment / alignment error for the pipe, workers are sent instructions on the installation and thickness of the gaskets needed to correct the positional misalignment / alignment error. Workers remove the clamp, install gaskets and replace the clamp. This process is repeated until the measuring sensor accepts pipe alignment.

[00844] In one embodiment, the purge and inspection system 7001 or the internal welding system 5004 may include two clamps. For example, one clamp is designed and configured to grip the inner surface of the first pipe 1022b. In one embodiment of the invention, the crane operator moves the second / inlet pipe 1022a to the desired position. In one embodiment, the second clamp is designed and configured to grip the inner surface of the second / inlet pipe 1022a. In one embodiment, one or more processors 7062 or 5140 are configured to interact with a measurement sensor 5056 or 7042 to verify alignment between the pipes. If the measuring sensor 5056 or 7042 detects an error in the angular displacement / alignment of the pipe, the second clamp releases the second pipe and commands to correct the displacement are sent to the crane operator. If the measuring sensor 5056 or 7042 detects an error in the positional displacement / alignment of the pipe, the second clamp releases the second pipe and the workers are sent instructions on the installation and thickness of the gaskets necessary to correct the error of the positional displacement / alignment of the pipe. The crane operator moves the second pipe further from the first pipe, and workers install gaskets. The crane operator moves the second pipe back. The second clamp captures the second pipe. This process is repeated until the measuring sensor accepts pipe alignment.

[00845] In FIG. 103B illustrates alignment, welding, and inspection processes of the internal welding system 5004.

[00846] In one embodiment, the measurement sensor 5056 scans 360 ^{about the} area of the contact surface 5136 between the pipes 1022a, 1022b before performing any welding. In one embodiment of the invention, during the process of generating the state profile data before welding, the measurement sensor 5056 is located between the clamps and / or seals of the internal welding system 5004 and turned on. In one embodiment of the invention, the welding torch (s) 5502 are turned off during the process of generating the state profile data before welding. In one embodiment of the invention, one or more processors 5140 are configured to interact with a measurement sensor 5056 to scan the area of the contact surface 5136 to obtain state profile data before welding after engaging, respectively, the first clamp 5142 and the second clamp 5144 with the first pipe 1022a and second pipe 1022b.

[00847] In one embodiment, platforms 5330 (as illustrated in FIGS. 10A and 10B) as well as 6010A and 6010B (as illustrated in FIG. 73) are controlled by one or more processors 5140 (or otherwise controlled) to mesh with external surfaces 5346 and / or 5348 (as illustrated in FIG. 2G) of the first pipe 1022a and / or second pipe 1022b for adjusting the relative position of the pipes 1022a, 1022b in the event that the state profile data before welding determines that adjustment is required. In one embodiment, the inner surface 5130, 5132 of the first pipe 1022a and / or the second pipe 1022b is engaged and controlled by the first clamp 5142 and the second clamp 5144, respectively, to adjust the relative position of the pipes 1022a, 1022b when the profile data states before welding determine that adjustment is required.

[00848] In one embodiment, during the process of generating profile data generated on the fly, the measurement sensor 5056 is positioned between the clamps and / or seals of the internal welding system 5004 and turned on. In one embodiment of the invention, one or more processors 5140 are configured to control the position and speed of the welding torch 5502 (or 7502) based on the welding profile data obtained on the fly. In one embodiment of the invention, an on-the-fly scanning / verification procedure is performed during the passage procedure when welding the root of the seam. In one embodiment of the invention, an optional radiographic verification procedure can be performed (for example, 1044, as illustrated and described with reference to Fig. 1B) between the on-the-fly scan / scan and weld root pass test and on-the-fly scan procedure »/ Inspection and filling and facing passage.

[00849] In one embodiment of the invention, the measuring sensor 5056 scans 360 ^{about the} area of the contact surface 5136 between the pipes 1022a, 1022b after performing the welding operation. In one embodiment, during the post-weld state profile data generation procedure, the measurement sensor 5056 is positioned between the clamps and / or seals of the internal welding system 5004 and turned on. In one embodiment of the invention, the welding torch (s) 5502 is turned off during the post-welding state profile data generation procedure.

[00850] In one embodiment of the invention, the weld verification procedure (for example, 1008, as illustrated and described with reference to Fig. 1B) may be performed after the scanning / verification procedure after welding.

[00851] The procedures illustrated in FIG. 103B are described with respect to the internal welding system 5004. However, as illustrated in FIG. 103B, it is contemplated that the same procedures apply to the lash welding system of pipeline 3001 and the purge and inspection system 7001 and, therefore, will not be described again with reference to the lash welding system of pipeline 3001 and the purge and inspection system 7001.

[00852] Since in one or more embodiments of the invention, the pipe is internally welded (that is, the weld root pass is made inside the pipe), the resulting root weld can be excellent because it better takes into account any mismatch and / or areas of mismatch or step transition, inside the pipe. In addition, if a hot welding passage (second weld layer over the root bead) is also used internally, the pipe can also be provided with reliable root reinforcement over the passage when welding the root of the seam. A hot welding passage, as well as an additional welding passage made inside, can provide a small curved protrusion that slightly enters the pipe to further strengthen the pipe. For example, the inner diameter of the pipe can be designed so that in the area of the weld be slightly smaller than the inner diameter of the welded pipe in areas in which there is only pipe material without welding. In one aspect of the present application, the hot weld passage of the weld metal has at least a portion in areas closer to the longitudinal axis of the pipe than the inner surfaces of the welded pipes in areas of the welded pipes directly adjacent to the weld metal on opposite sides of the weld metal placement .

[00853] In some embodiments of the invention, the internal welding system 5004 disclosed herein is configured to weld pipes of at least 30 'length. In other embodiments of the invention, the internal welding system 5004, 3001 disclosed herein is configured to weld pipes with a diameter of 26 ″ inches or less. In yet other embodiments, the internal welding system 5004 may weld pipes with a diameter of less than 24 ″ inches. In still other embodiments, the internal welding system 5004 disclosed herein is configured to weld pipes that are at least 30 'in length and less than 24''in diameter.

[00854] FIG. 73-85 illustrate and disclose another embodiment of an internal welding system in accordance with another embodiment of the present patent application.

[00855] This patent application provides a system for leveling and welding surfaces of two pipe segments. This system contains an external alignment mechanism and a welding mechanism. External alignment mechanisms can be as complex as the control modules illustrated in graphic materials, or as simple as a type-tone clamp, as illustrated in US Pat. No. 1,693,064. The mechanisms used may also be suitable for constructing a pipeline on shore or at sea. US patent No. 1693064 is incorporated herein by reference in full. Regardless of which mechanism is used, an external alignment mechanism maintains and adjusts in position each segment so that the segments are virtually collinear or axially aligned along their longitudinal axes.

[00856] An external alignment mechanism may support the pipe segment and may include power elements that allow the position and orientation of the pipe to be adjusted. In particular, the external alignment mechanism may comprise rollers that allow the pipe to move in the longitudinal direction. The pipe can also be supported by rollers that allow the pipe to roll around the longitudinal axis and move it up and down. Adjustment of position and orientation can be automated using engine power or hydraulic power controlled at the operator's station or fed to a central controller that automatically monitors and aligns segments based on specified alignment parameters or feedback from an internal laser that reads the contact surface or connection profile.

[00857] The welding mechanism is an internal welding machine that uses welding (for example, arc welding with a metal electrode in a GMAW shielding gas) from inside the pipe segments to the front weld or edge connection of the segment to the inside of the v-shaped hole formed by the beveled edges of the two segments pipes (other cross-sectional shapes other than V-shaped can also be used). The welding mechanism comprises a load carriage capable of engaging the inner walls of the pipe in order to be fixed or fixed inside the pipe in a fixed position, and a welding part supported for rotation by the carriage inside the pipe. In particular, the internal welding machine is located inside the aligned pipe, and then is located in the longitudinal direction so that the welding head or torch is in the longitudinal direction in close proximity to the edge connection. The welding mechanism also includes a rotating mechanism for rotating the welding part relative to the carriage. The welding head or torch is rotatably supported on the welding part near the longitudinal axis of the pipe so that the welding torch can closely follow the entire inner surface of the joint in orbital rotation. In particular, during welding, the joint head torch follows the edge joint around the entire circumference of the pipe, depositing the weld metal. In addition to circular rotation relative to the carriage, various control elements can move the welding head axially along the pipe relative to the carriage radially towards and away from the joint and pivotally around a point or axis (for example, an axis parallel or perpendicular to the longitudinal axis AA of the pipe ) The controller can control the rotation of the burners. These degrees of swivel joint free running contribute to the very efficient and productive operation of the welding head when filling the profiles of the contact surfaces in the optimal mode and where necessary.

[00858] The welding mechanism also includes a laser tracking mechanism that works in conjunction with a torch of the welding part to detect a contact surface profile and / or a weld metal profile for depositing a weld metal on an edge joint in an appropriate place and quantity. The laser mechanism examines the welding and sends a signal to the controller of the articulated weld head to control the movement of the head around the entire edge joint. In particular, the torch follows the laser, while the welding head control system constantly receives weld profile information from the edge joint. The information is then used to continuously adjust the burner to achieve the desired weld structure.

[00859] In addition to the laser tracking mechanism, the system may include a 2D camera for visually checking welding. The 2D camera is mounted on the welding part and follows the torch in such a way that the operator can check the state of welding immediately after it is completed by the torch. A visual signal is supplied to the operator’s external display. For example, a 2D camera may be a color camera, and a color change may indicate to the operator a welding defect. An alleged change in profile may also indicate a defect.

[00860] As illustrated in FIG. 73-75, the following describes a system for welding pipe segments. In FIG. 73, an external alignment mechanism 6010A and 6010B is illustrated, which is configured to support, position, and move multiple lashes of a pipeline. Each mechanism 6010A and 6010B may contain supports (e.g., rollers) on which tubing can be supported. The longitudinal roller 6012 movably supports the pipeline segment 6105 so that the segment 6105 can be re-positioned along its longitudinal direction indicated by arrow A. In addition, the rotary rollers 6014 are rotatable around an axis parallel to the axis AA of the support segment 6105 on each from the sides of segment 6105, allowing them to rotate or adjust the angular orientation of segment 6105 relative to the axis AA. The external alignment mechanism 6010 is configured to automatically manipulate several segments, arranging them in various positions and orientations using motors, hydraulic mechanisms, etc. For example, segments can be raised, lowered, rotated, tilted, scrolled, etc.

[00861] As illustrated in FIG. 73, the external alignment mechanisms 6010A and 6010B support several segments 6105, 6110 and adjust their position and orientation until both segments 6105, 6110 are aligned so that their longitudinal axes AA are collinear and one end of each of the segments 6105, 6110 rested against the edges of the contact surface. In particular, in FIG. 74 is an enlarged view of the part 6100 illustrated in FIG. 73, on which the edges form the contact surface of the pipe 6120 (known as a “seated” joint).

[00862] The pipe alignment and welding system in accordance with this patent application performs welding on the inside of the contact surface 6120 from the inside of the mounted segments 6105, 6110. To perform welding on the outer surface of the joint 6120, the internal welding mechanism 6300 rolls into one end of one of the segments 6105, as illustrated in FIG. 75. Then, the second segment 6110 is placed on the external alignment mechanism 6010B and manipulated until both segments 6105, 6110 are properly aligned. Then, an external force may be applied to the drive rod 6345 of the internal welding mechanism 6300, or the mechanism may include automatic self-propelling means for adjusting its axial position in the aligned segments 6105, 6110.

[00863] As illustrated in FIG. 76-79, the welding mechanism 6300 comprises a carriage 6301 and a welding part 6302. The carriage 6301 contains at least one alignment mechanism 6340A, 6340B, which can be expanded in the radial direction to engage with the inner surface of the segment 6105 or 6110. This expansion and engagement provides axial / longitudinal position of the welding mechanism 6300 relative to the segment 6105, 6110 and aligns or radially centers the welding mechanism 6300 in the segments 6105, 6110. The carriage 6301 also includes a housing 6311 on which the rotation mechanism 6335 is supported. AA 6311 is composed of several elongate structural support elements which extend between the alignment mechanisms 6340A and 6340B. As described below, the welding part 6302 contains a similar corresponding construction 6313.

[00864] The welding part 6302 is rotatably connected to the carriage 6301 and extends from the end of the carriage 6301. The relative rotation between the carriage 6301 and the welding part 6302 is facilitated by the rotation mechanism 6335. The rotation mechanism 6335 is attached to the carriage 6301 and automatically (by means of an engine and gearing) rotates the welding part 6302 relative to the carriage 6301 around the longitudinal axis AA. The welding portion 6302 may be cantilevered to the carriage 6301, or may be supported by an additional alignment mechanism 6340C, such that the torch 6305 is located between the alignment mechanisms 6340B and 6340C. When a 6340C alignment mechanism is provided, the welding part 6302 rotates relative to and between both alignment mechanisms of the 6340B and 6340C, when the alignment mechanisms of 6340B and 634 ° C expand to secure themselves within the segment. In addition, the carriage 6301 may include a drive rod 6345, which can be made in the form of an elongated extension from the carriage 6301, which the operator can grab to insert / push or pull / pull the welding mechanism 6300 with respect to its axial position in the segment 6105, 6110.

[00865] In FIG. 76 is an enlarged view of a section 6200 illustrated in FIG. 75, in which only segment 6105 is present, and segment 6110 is absent. As illustrated in FIG. 76, the welding part 6302 comprises a welding unit 6303, which comprises a torch 6305, a laser sensor 6310 and a color camera 6320. The welding part 6302 further has a housing 6313 on which a torch 6305, a laser sensor 6310 and a color camera 6320 are supported. A laser sensor 6310 monitors the internal the connection of segments 6105, 6110 and detects the profile of the contact surface, which should be used to place the torch 6305 when performing welding on the contact surface of the connection. Housing 6313 extends between alignment mechanisms 6340B and 6340C. Section 6200 illustrates a welding mechanism 6300 located inside segment 6105, with the torch 6305 typically pointing radially outward and positioned to weld the mating surface 6120. FIG. 77 illustrates an embodiment of a general schematic cross-section of the welding mechanism 6300 through section BB, which illustrates the welding unit 6303 in the direction of insertion of the welding mechanism 6300. FIG. 77 also illustrates the direction D of rotation of the welding unit 6303 when turning using the rotation mechanism 6335. Therefore, the welding process at a certain point along the welded joint 6120 will be primarily performed by a laser sensor 6310, followed by a torch 6305 and, finally, 2D- check chamber 6320.

[00866] FIG. 82-84 illustrate several views of the welding part 6302. In FIG. 82 illustrates a wire delivery system 6322. A wire feed system 6322 includes a coil for winding a welding wire 6323, an additional wire dressing device 6325, and a wire feed mechanism 6330, which is automatically controlled to deliver the appropriate amount of wire to the torch 6305. While the rotation mechanism 6335 turns the welding part 6302, the wire delivery system 322 feeds the wire to the torch 6305.

[00867] As mentioned above, the burner 6305 can be positioned and oriented in various ways using various mechanisms. Burner 6305 is supported on the manipulator. The manipulator comprises a radial positioner, an axial positioner and a rotation device. In particular, a radial positioner 6307 (for example, a strut and gear) that supports the torch 6305 is capable of moving the torch radially in the direction and from the inner surface of segments 6105, 6110. In other words, in the direction and from the contact surface of segments 6105, 6110 to be welded. In addition, an axial positioner 6309 (for example, a strut and gear) can move the burner 6305 in the axial direction inside the segments 6105, 6110. The manipulator also includes a rotation device 6308 that allows the burner to rotate (for example, around an axis parallel to the longitudinal axis AA of the segment). The torque by means of the rotation device 6308 may be driven by a motor and gearing 6306. For example, the motor may be a stepper motor.

[00868] The burner manipulator can combine the manipulation movements of the above elements due to the interdependent support of the elements. For example, the housing 6313 may support an axial positioner, which in turn supports a radial positioner, which in turn supports a rotation device, which in turn supports the burner. Similarly, an axial positioner may be supported by a radial positioner. In addition, any support order may be used.

[00869] The manipulator elements are controlled by a controller that receives a series of signals as an input signal, including a signal from a laser 6310, and then processes the information before transmitting the signal to at least a radial positioner 6307, an axial positioner 6309, a rotation device 6308, and a wire delivery system 6322. Then, the burner 6305 is re-moved and continuously reoriented in accordance with the set parameters of the controller based on the signals received from the profile-reading laser 6310.

[00870] Next, operation of the present internal welding system will be described. In FIG. 73, 80 and 81 illustrate the process of positioning and welding together segments 6105 and 6110. During operation, one or more of the following indicated steps can be performed in such a way that: a) the pipe segment 6105 is placed on the alignment device / stand of the pipe 6010A; b) then the internal welding mechanism 6300 is inserted into the pipe segment 6105; c) then the second pipe segment 6110 is aligned with the pipe segment 6105, and the welding mechanism 6300 is pulled forward by the drive rod 6345 or automatically actuated so that the torch 6305 as a whole is connected to the mating surface 6120 of the pipe segments 6105, 6110; d) then alignment mechanisms 6340A, 6340B (and, if necessary, 6340C) are engaged to secure the welding mechanism 6300 inside the pipe segments 6105, 6110; e) in one embodiment of the invention (optionally), the rotation mechanism 6335 rotates the welding head 6305 to perform an initial scan of the connection of the contact surface 6120 of the pipe segments 6105, 6110 using the laser sensor device 6310 to ensure an optimal fit; f) if required, steps (c), (d) and (e) can be repeated, that is, pipe segments 6105, 6110 are re-aligned / rotated and re-scanned by laser 6310 to improve “fit”; g) optionally, an internal 634 ° C alignment mechanism on the rear side of the welding mechanism 6300 engages to hold the welding mechanism 3600 in axial position with respect to both pipe sections 6105, 6110; h) using the welding mechanism 6300, fixed in the pipe segments 6105 and 6110, the weld root welding cycle (first welding) starts so that the laser sensor 6310 scans the contact surface of the pipe 6120, the torch 6305 follows the laser sensor 6310, and the output from laser sensors 6310 are used to control the position of the articulated torch 6305, while the position and orientation of the torch 6305 relative to the contact surface 6120 are controlled in such a way as to provide better welding quality; i) in addition to the signal from the laser sensor 6310, end-to-end control of the arc current can also be used to control the position of the torch; j) after welding is completed 360 °, the welding head 6305 is turned back to its original position; k) the profile (using a laser sensor 6310) and visual checks (using a 2D color camera 6320) are performed either in the previous step (j) or in a separate control run; l) after testing, the alignment mechanism 6340A-C is released, and the welding mechanism 6300 extends or advances to the open end of the welded pipe 6105, 6110 with the nose fairing of the welding mechanism 6300 exposed, similar to step (b), the pipe segment 6110 is placed on the external alignment mechanism 6010B and advances to the next connection; m) then steps (c) to (l) are repeated for the entire production cycle.

[00871] In one embodiment, the signal from the laser sensor 6310 is sent to the electronic controller of the external alignment mechanism 6010 to automatically re-position one or both segments 6105, 6110 for a more desirable location of the mating surface 6120. In addition, the above steps can be performed in this order. Nevertheless, variations of this order are also considered.

[00872] In another embodiment, instead of stopping after the first 360 ° welding, the rotation continues to make another welding pass, and the laser sensor 6310 can be used both for checking and tracking, while the rear 2D color camera continues checking after completing the second welding.

[00873] In yet another embodiment of the invention, instead of welding a full weld at 360 °, welding is performed in two steps of 180 ° with the same initial position. For this embodiment, either a few laser sensors for tracking or a mechanism for physically oscillating the laser and / or burner to maintain the position of the leading tracking sensor in both directions of rotation (i.e., turn the burner and the laser sensor so that they switch to other positions) will be required. )

For example, gas flow from these gas sources can be monitored (continuously or at regular intervals). In one embodiment of the invention, the transmitter of the lash welding system of pipeline 3001 transmits gas level information in a completely wireless manner to a remote uLog processing system for further processing. For example, information about the monitored gas level in the integrated gas source can be used to determine the estimated remaining runtime of the lash welding system of pipeline 3001. In one embodiment of the invention, one or more processors of the lash welding system of pipeline 3001 can be configured to determine the estimated remaining runtime of the system for welding lashes of pipeline 3001 locally in a system for welding lashes of pipeline 3001.

[00884] In one embodiment, one or more processors and one or more sensors of the lash welding system of pipeline 3001 are configured to monitor the level of the welding wire material in the lash welding system of pipeline 3001. For example, rotation of a wire feed motor (which distributes the welding wire) and the weight of the remaining welding wire in the lashing system of the pipeline 3001 can be monitored (continuously or at regular intervals) to determine the levels of material of the welding dies in the lash welding system of pipeline 3001. In one embodiment of the invention, the transmitter of the lash welding system of pipeline 3001 transmits information about the monitored level of material of the welding wire in a completely wireless manner to a remote uLog processing system for further processing. For example, information about the monitored level of the welding wire material can be used to determine the estimated remaining operating time of the lash welding system of the pipeline 3001 (i.e., before the material of the welding wire ends or is below the minimum threshold level for the operation of the lashing system of the pipeline 3001 ) In one embodiment of the invention, one or more processors of the pipe lash system 3001 may be configured to determine the estimated remaining operating time of the pipe lash system 3001 locally in the pipe lash system 3001.

In one embodiment, the remote uLog processing system can also be configured to transmitting (completely wirelessly to the lash welding system of pipeline 3001) further commands for operating the lash welding system of pipeline 3001 based aschetnogo remaining operating time of the welding system 3001 lashes pipeline.

[00885] In one embodiment of the invention, the uLog remote processing system receives battery charge data from a number of pipe lash welding systems located in different places (for example, in different places throughout the country or around the world), and creates a database based on them . This database is used by the uLog processing system to determine, based on a large data set, the estimated battery life based on various operating parameters of the internal welding system. This can be used by the uLog processing system and / or one or more processors of the lash welding system of pipeline 3001 to predict battery life for various components based on the current operating conditions of these components. This information can be used by one or more processors to reduce or control the energy consumption of one or more components by changing one or more operating parameters. For example, welding speed, wire feed speed, voltage and current can be adjusted (for example, lowered) to extend battery life if one or more processors determine that such operating conditions can be changed without affecting the corresponding operation.

[00886] In one embodiment, the battery life, output voltage, and any operating parameters are sent wirelessly to a user interface, such as a computer monitor having a computer display, so that a user can control them.

[00887] In one embodiment of the invention, the lash welding system of conduit 3001 also includes a power section 3008 located adjacent to the drive section 3006 (that is, on the rear side of the lashing system of conduit 3001).

[00888] In one embodiment, with reference to FIG. 101, the front section 3002 comprises a frame of the front section 3522, the central section 3004 comprises the frame of the central section 3524, the drive section 3006 comprises the frame of the drive section 3526, and the power section 3008 comprises the frame of the power section 3528.

[00892] In one embodiment of the invention, the motor power supply 3012 is configured to power the drive motor 3124 in the drive section 3006. In one embodiment, the motor power supply 3012 may comprise a plurality of motor power batteries 3012a-3012e. In one embodiment of the invention, the motor power source 3012 may also be referred to as a drive power source. In one embodiment of the invention, the motor power source 3012 is attached to the frame assembly of the lash welding system of pipe 3001. In one embodiment, the number of engine power batteries may vary. In one embodiment of the invention, the motor power source 3012 is only used for driving (i.e., powering the drive motors 3124 in the drive section 3006) so that if the other batteries 3014a-3014e are discharged, the lash welding system of the pipe 3001 will not get stuck in the pipe.

[00893] In one embodiment of the invention, a motor power supply 3012 (including batteries 3012a-e) and a welding torch power supply 3014 (including batteries 3014a-e) are mounted on a frame of the lash welding system of pipe 3001. In one embodiment, one or more battery packs elements (for example, a power source for the engine 3012, a power source for the welding torch 3014, batteries 3514, etc.) of the lash welding system of the pipe 3001 are configured to power the drive motor 3124, the measuring sensor and the welding torch. In one embodiment, one or more battery cells 3514, 3012, or 3014 of the lash system of the internal welding conduit 3001 may comprise a plurality of independent battery cells. In one embodiment of the invention, the battery cells 3014, 3014a-e for the welding torch are independent of the battery cells 3012, 3012a-e, 3514 for the drive motor and the measurement sensor. In one embodiment, the battery cells 3012, 3012a-e for the drive motor 3124 are independent of the battery cells 3514 for the measurement sensor. That is, in one embodiment of the invention, the battery cells 3012, 3012-E are configured to power the drive motors 3124, the battery cells 3514 are configured to power the measurement sensor, and the battery cells 3014, 3014a-e are configured to power the welding torch of the pipe lash welding system 3001

[00894] In one embodiment, with reference to FIG. 101, the drive motors 3124 are configured to drive the rollers 3125 so as to move the frame or frame assembly of the lash welding system of pipe 3001, the first pipe engaging device 3127, the second pipe engaging device 3129, and the measuring sensor 3130 of the lash welding system of pipe 3001 at least along one of the pipes 1022a, 1022b inside it. In one embodiment of the invention, the drive rollers 3125 are configured to interact with the inner surfaces 5130, 5132 of one or more pipes 1022a, 1022b. In one embodiment of the invention, the lash welding system of pipeline 3001 comprises a plurality of drive rollers 3125 that are rotatable to support the frame of the lash welding system of pipeline 3001.

[00895] In one embodiment, the welding energy sources 3016 are configured to receive direct current power from a power source of the welding torch 3014 and convert the direct current power into appropriate current and voltage forms for the welding procedure performed by the welding torches 3502.

[00896] In one embodiment of the invention, the adjustable wheels 3018 are designed and adjustable so that the power section 3008 of the lash welding system of conduit 3001 runs straight and even in the conduit.

[00897] In FIG. 103, a diagram illustrating a power flow, including welding power, communication data and control data through a lash welding system of a pipe 3001, is illustrated, with some components of the lash welding system of a pipe 3001 not illustrated for ease of presentation and to better illustrate other components and / or functions of the lash system pipeline 3001.

[00898] The flow of communication data and control data through the lash welding system of pipeline 3001, illustrated in FIG. 103 is similar to the flow of communication data and control data through the internal welding system 5004 illustrated in FIG. 71, except as noted below.

[00899] In one embodiment, the electronic module of the drive section 3126 is operatively coupled to drive batteries 3012 located in a power section 3008 of the lash welding system of pipe 3001.

[00900] In one embodiment of the invention, the batteries 3012 of the power section 3008 are connected to the drive motors 3124 of the lash welding system of the pipe 3001 through an electronic module of the drive section 3126.

[00901] The flow of welding power through the lash welding system of conduit 3001, illustrated in FIG. 103 and 103A differs from the welding power flow through the internal welding system 5004 illustrated in FIG. 71.

[00902] For example, the welding power is supplied from different sides to the internal welding system 5004 and the lash welding system of the pipeline 3001. That is, unlike the internal welding system 5004, when the welding power is supplied from the front of the system through its halyard 5034, the welding power comes from the back of the lash welding system of the pipeline 3001. Such a configuration in which welding power is supplied from the back of the lash welding system of the pipeline 3001 can be achieved by adding a second slip ring or path rotation of the welding part and pushing it back through the tube (which can impede access to the coils of welding wire for maintenance).

[00903] In one embodiment, the welding power is received by the welding torches 3502 of the lash welding system of the pipe 3001 from the integrated power source of the welding torch 3014. In one embodiment, the welding power from the integrated power source of the welding torch 3014 is supplied to welding power sources 3016. In one an embodiment of the invention, welding power sources 3016 are configured to generate a welding arc. That is, welding power sources 3016 are configured to receive direct current power from a welding torch power source 3014 and convert the direct current power into appropriate forms of current and voltage for the welding procedure performed by welding torches 3502. In one embodiment of the invention, appropriate forms of current and voltage from sources of welding power 3016 are fed to welding torches 5502 through the rear current collector ring 3512.

[00904] Like the internal welding system 5004, in one embodiment of the invention, the batteries 3514 of the drive section 3006 are configured to supply power to all electronic modules of the lash welding system of pipe 3001, including a front electronic module, an electronic wire feed module, an electronic module of the central section and an electronic the module of the drive section 3126, and also configured to supply power to all drive electric motors of the lash welding system of the pipeline 3001, including the front rotation motor, the engine and wire feed systems, rear rotation motor, welding torch axial motor, welding torch radial motor and welding torch tilt motor. In one embodiment of the invention, the batteries 3514 are configured to power the test chamber and / or the measurement sensor of the lash welding system of the pipeline 3001. However, the batteries 3006, 3514 of the drive section are not configured to supply power to the drive motors 3124 of the lash system of the pipeline 3001. In one embodiment of the invention, the batteries 3012 of the power section 3008 are configured to supply power to the drive motors 3124 of the lash welding system of pipeline 3001. In one embodiment of the invention 3012 The batteries power section 3008 are connected to drive motors 3124 lashes pipeline welding system 3001 through 3126 drive electronics module section.

[00905] In one embodiment of the invention, the batteries used by the lash welding system of conduit 3001 can be electrically connected to each other to produce higher current and higher energy consumption. For example, two 12-volt batteries can be connected together to get 24 volts. In one embodiment of the invention, both batteries are mounted on the same frame and connected in series. In one embodiment of the invention, the batteries can also be connected to each other (for example, via a universal joint or otherwise) so that the batteries can be articulated to each other for maneuvering inside the pipe.

[00906] In one embodiment of the invention, the lash welding system of conduit 3001 may contain four batteries, one of which can be used to actuate the lashing system of conduit 3001, and the remaining three batteries can be connected in parallel and can be used for welding procedures in the welding system lashes of the pipeline 3001.

[00907] In one embodiment of the invention, internal (located inside the pipes) clamps or external (located outside the pipes) clamps can be used in the whip welding system of pipe 3001. For example, in one embodiment of the invention, the internal (located inside the pipe) clamps during welding procedures may be used in the lash welding system of pipe 3001. In one embodiment of the invention, external (located on the outside of the pipe) clamps during the internal scanning procedure (when the internal laser / sensor and / or other device is configured to scan the weld inside the pipe) can be used in the lash welding system of pipe 3001.

[00908] The welding of pipe lashes is performed to weld long pipe lashes to other long pipe lashes. Typically, the new pipe to be welded is at least 120 feet long and can be more than two miles long. The internal welding machine disclosed herein has built-in battery power and can be used to hold the bundle in the root welding passage and, optionally, the hot weld passage inside the pipe.

[00909] In one embodiment, the pipes are aligned externally. Like the internal welding machine disclosed in this document, the pipe lash welding machine can be equipped with only one welding head (with one welding torch) or multiple welding heads (for example, anywhere from 2 to 8).

[00910] As illustrated in FIG. 103C and 103D and it will be understood from the description given above that the apparatus for welding the lashes of the pipeline 9000 has a nose fairing section 9002 for electronics, the supporting wheels 9004, an integrated welding power source 9006 and a pair of clamps 9008, which guarantees an internal apparatus for welding the lashes of the pipeline concentric shape suitable for the shape of the pipe. As will be described in more detail later, the apparatus for welding pipe lashes comprises clockwise and counterclockwise replaceable elements of the welding head 9010 with separate lasers and 2D color cameras. In FIG. 103C and 103D, the pipe lash welding apparatus is illustrated in a slightly bent (e.g., bent 30D) pipe 9012, the inner diameter of which is 38 inches. As also illustrated in FIG. 103C and 103D, the pipe lash welder has a 9014 drive and brake system that is offset 90 degrees to reduce length, as well as a built-in power supply (such as a battery pack) 9020 for the drive motor and brakes.

[00911] As will be understood from FIG. 103E-J and the following description, the illustrated model has four welding heads, with two of them turning clockwise (welding heads 9022 and 9024) during a welding operation and two of them turning counterclockwise (welding heads 9032 and 9034) in welding operation time. In an alternative embodiment of the invention, all 4 welding heads are rotated in one direction of rotation, as described elsewhere in this application. Furthermore, in the embodiment of the invention illustrated in FIG. 103E-J, there are four built-in welding power / power sources (eg batteries), designated 9042, 9044, 9046, 9048. The more welding heads / torches provided, the shorter the welding cycle time. This is applicable both when welding is performed in one direction of rotation, and when it is performed in a direction both clockwise and counterclockwise. However, it should be understood that the rotation in one direction of rotation can occur faster than the rotation both clockwise and counterclockwise, while the latter can be used to change the direction of rotation of the engine.

[00912] Each of the welding heads 9022, 9024, 9032 and 9034 has the following equipment: a welding torch, at least one torch engine of the type described above to provide angular, axial and lateral movement of each torch, a wire feed device, wire straightening devices and a wire spool for feeding the material of the welding wire to the welding torch. A laser control / sensor device of the type described above is also provided for guiding the welding torch and checking welding. In addition, a CCD / CMOS color camera is used to test welding as described above.

[00913] Each welding head is connected and connected to one of four power sources 9042, 9044, 9046 and 9048. Four welding heads and four power sources are mounted on the rotation unit 9050. The rotation unit performs the same function as the rotary hub 5078 described higher. The rotation unit may be driven by one or more orientation motors, as described above.

[00914] To perform the welding operation, the apparatus for welding the lashes of the pipeline is fed to one open end of one of the pipes, for example, a shorter pipe or pipe with less obstructions to be eliminated. The end of the second pipe is aligned and aligned (outside) with the end of the first pipe. The apparatus for welding the lashes of the pipeline goes to where the welding heads are located directly in the area of the contact surface of the pipe. The laser sensor provides feedback, and at least one welding torch motor aligns the tips of the welding torch, bringing them to the appropriate position on the contact surface. The clamps 9008 are actuated and expanded (they function as an expander) to make the apparatus for welding the pipe lashes coaxial with the pipes, and the clamps are used to hold the position of the apparatus for welding the pipe lashes. When the apparatus for welding the lashes of the pipeline is fixed with clamps, the rotation axis of the rotation mechanism 9050 is aligned with the longitudinal axis of the pipe 9012.

[00915] In one embodiment of the invention, welding is carried out, primarily by controlling the welding heads 9032 and 9034 counterclockwise. As illustrated in FIG. 103H, the four welding heads are spaced apart from each other rotationally at an angle of 90 degrees. Welding heads 9032 start working for 12 hours, and welding heads 9034 start working for 9 hours, as illustrated in FIG. 103H as they begin welding. The rotating assembly 9050 rotates 90 degrees until the welding head 9032 finishes working for 9 hours and the working head 9034 finishes working for 6 hours (see progress in Figs. 103H and 103I). At this point, the welding heads 9032 and 9034 stop welding (Fig. 103I), and welding starts the welding heads 9022 and 9024 (Fig. 103I). Then, one or more orientation motors rotate the rotating assembly 9050 in a clockwise direction, as illustrated in FIG. 103J until the welding head 9022 has finished working for 3 hours and the welding head 9024 has finished working for 6 hours. This completes the complete root welding pass.

[00916] After performing the root welding pass, the rest of the welding operation can be performed externally, either using automatic welding machines or manually. Then the expanders or clamps are disconnected, and the apparatus for welding pipe lashes is pushed to the open end of the pipe.

[00917] In one embodiment, each of the power supplies 9042, 9044, 9046, and 9048 comprises a replaceable element with a rechargeable battery that can be inserted into a corresponding hole 9062, 9064, 9066 and 9068.

Thus, the welding torches may not necessarily be fixed at a given welding angle (this applies to any of the internal welding machines described in this document, either autonomous or non-autonomous), so that the tip of the torch indicates the direction of welding forward (weld pool " pushed ”). Alternatively, as discussed above with reference to FIG. 56A, welding torches can be mounted to rotate relative to point P such that the axis A of the welding torch can be located on both sides of the radial line R. This alternative allows the same welding torch to be used for both clockwise and welding counterclockwise by turning the welding torch so that it can rotate in the direction of welding, regardless of whether welding is performed clockwise or counterclockwise.

[00972] In FIG. 97 illustrates a partial view of the purge and inspection system 7001, in which the measuring sensor 7042 and chamber 7044 are arranged to inspect the pipes from the inside, while the external welding torch 7502 of the external welding system 7500 is configured to weld outside the pipes 1022a, 1022b. In one embodiment of the invention, an external welding torch 7502 may be mounted on the outer surface of one of the first pipe and second pipe 1022a, 1022b.

[00973] For example, in FIG. 97 illustrates the perfect alignment of the welding torch 7502 with a groove cut 7106 (along the longitudinal axis AA of the pipes 1022a, 1022b). In FIG. 98, a close-up view of a welding torch 7502 is shown, combined with the cutting of a seam 7106. The pipes 1022a, 1022b illustrated in FIG. 97 and 98, are fully aligned and do not have a step transition.

[00974] In FIG. 99 and 100 illustrate a close-up view of the external welding torch of the external welding system used in the prior art system and the purge and inspection system 7001, respectively, where the pipes have alignment of clearance and radial displacement (step transition). For example, as illustrated in FIG. 99 and 100, the pipes 1022a, 1022b have a gap of 1 millimeter and a radial displacement (step transition).

[00975] As illustrated in FIG. 99, in the prior art system, the raised end of the work protects the right side of the weld edge, which reduces weld penetration. As illustrated in FIG. 100, the external welding system 7500, used in conjunction with the purge and test system 7001, is configured to receive welding profile data (for example, before, during, and after the welding procedure) from the purge and test system 7001 and is biased based on the received welding profile data, its external welding torch 7502 and / or the inclination of its external welding torch 7502 to achieve full penetration of the welding. Thus, the welding profile data obtained from the purge and inspection system 7001 can be used by the external welding system 7500 to improve welding.

[00976] The following describes the operation of the purge and test system 7001. In one embodiment of the invention, the purge and test system 7001 is configured to operate in a repeating cycle.

[00977] After it has been determined that welding is completed on the current weld, one or more processors 7062 (computer system 7060) are configured to transmit communication signals to an electronic purge module 7032 for controlling (via control signals) the low purge valve 7016, a high purge valve 7022 and a secondary low purge controller 7020 to blow off the purge seals 7046 and 7048. One or more processors 7062 are also configured to send communication signals to the electronic module of the front section 7036 for controlling / disabling (via control signals) the front clamp control valve 7056 to retract the first engagement device 7050 to its original, retracted position and / or to deflate the purge seal 7046. One or more processors 7062 are also configured to send communication signals to the electronic module the central section 7040 for controlling / disabling (via control signals) the rear clamp control valve 7058 to retract the second engagement device 7052 in its original, retracted position and / or for blowing purge seals 7048. The purge and inspection system 7001 (including purge seals 7046 and 7048 and clamps 7050 and 7052) should be moved to the next weld.

[00978] In one embodiment, one or more processors 7062 is configured to send communication signals to an electronic module of a drive section 7064 to control (via control signals) drive motors 7068 to accelerate the purge system and check 7001 to move at a given speed, and then decelerations and stops at the next weld. In one embodiment of the invention, the predetermined speed at which the purge and test system 7001 is accelerated may be 6 feet / second.

[00979] When the second engagement device 7052 is located on the next weld, the electronic module of the drive section 7064 sends communication signals to the electronic purge module 7032 to check alignment with the end of the pipe. In one embodiment, the electronic purge module 7032 is configured to monitor (turn on) one or more test sensors 7042 to detect where the second engagement device 7052 is connected to the end of the pipe. In one embodiment, the swivel hub 7012 may not work when one or more of the measurement sensors 7042 detect where the second engagement device 7052 is connected to the end of the pipe.

[00980] In one embodiment, the electronic purge module 7032 is configured to send measured distance data to the electronic module of the drive section 7064. In one embodiment, the electronic module of the drive section 7064 is configured to control (via control signals) drive motors 7068 to move second engagement device 7052 according to the measured distance data.

[00981] In one embodiment, when the second engagement device 7052 is properly aligned and positioned relative to the end of the pipe, the electronic module of the drive section 7064 is configured to transmit communication signals to the electronic module of the central section 7040, so that the purge and inspection system 7001 of the control is in the required position on the next welded joint. In one embodiment of the invention, the electronic module of the central section 7040 controls (opens by means of control signals) a back clamp control valve 7058 to raise the second engagement device 7052 and to capture the old / existing pipe. In one embodiment of the invention, the electronic module of the center section 7040 controls the rear clamp control valve 7058 to simultaneously inflate the rear seal 7048.

[00982] Then, the next / new pipe segment 1002a is inserted and moved along the front section 7002 of the purge and inspection system 7001 to the desired position by the work team. At this time, one or more processors 7062 are configured to send communication signals to an electronic purge module 7032 to control one or more measurement sensors 7042 to verify pipe alignment. In one embodiment, one or more processors 7062 can rotate the rotary hub 7012 to perform measurements at multiple locations.

[00983] If the pipe alignment data is within the specified tolerance, the electronic purge module 7032 sends communication signals to the front electronic module 7036 to actuate and control the front clamp 7050. In one embodiment, the front electronic module 7036 controls / opens (via control signals) front clamp control valve 7056 for lifting the first engagement device 7052 and gripping a new pipe segment 1002a. In one embodiment, the front electronic module 7036 controls / opens (via control signals) the front clamp control valve 7056 to simultaneously inflate the front seal 7046.

[00984] If the pipe alignment data is within a predetermined tolerance, the electronic purge module 7032 sends communication signals (message) to one or more processors 7062 identifying a mismatch between the pipes 1022a, 1022b. In one embodiment of the invention, this information can be transmitted to the crane operator by typically received manual signals from the crane operator or as an electronic signal to a computer display terminal in the crane cabin.

[00985] After the pipe is clamped, one or more processors 7062 are configured to send communication signals to an electronic purge module 7032 for controlling one or more measurement sensors 7042 for measuring clearance and radial displacement (step transition) at a plurality of points along the circumference of the welded joint . In one embodiment of the invention, this data is communicated to one or more processors 7062 and compared with tolerances.

[00986] If the fitting of the connection (ie, clearance and radial displacement (stepped transition)) is within the specified tolerance, either one or more processors 7062 or the electronic purge module 7032 sends communication signals to the operator indicating that welding can be started .

[00987] If the fitting of the connection (that is, the clearance and radial displacement (stepped transition)) is not within the specified tolerance, a warning is sent to the operator and he can restart the clamp sequence or cancel the warning.

[00988] In one embodiment, the electronic purge module 7032 is configured to transmit control signals to the high purge valve 7022 to open and control the high purge controller 7024. In one embodiment, the electronic purge module 7032 is configured to continuously monitor oxygen readings in the purge gas chamber 7054 by means of an oxygen sensor 7026. When the measurement results of the oxygen sensor 7026 are below a predetermined content value oxygen (e.g., 500 ppm), the electronic purge module 7032 is configured to send control signals to the high purge valve 7022 to close and open the low purge valve 7016. In one embodiment of the invention, the measurement data of the oxygen sensor 7026 must be within a predetermined range (e.g. , from 50 to 100 ppm).

[00989] In one embodiment, while the high purge valve 7022 is open, the electronic purge module 7032, together with the electronic module of the front section 7036 and the electronic module of the central section 7040, are configured to use one or more measurement sensors 7042 to measure the gap and stepwise transition of the welded joint at several points along the circumference of the welded joint. The scan results are reported to one or more processors 7062 for pre-programming the external welding system 7500.

[00990] In one embodiment, after the low purge valve 7016 is closed, the secondary low purge controller 7020 is configured to maintain a constant predetermined pressure in the purge gas chamber 7054. In one embodiment, the secondary low purge controller 7020 is configured to maintain pressure in the range from 0.1 to 0.5 psi. inch and made with the possibility of termination of its work when the pressure exceeds 0.5 psi. inch.

[00991] In one embodiment of the invention, the pressure starts from a relatively high value (for example, 5 psi) and gradually moves to lower values as welding continues. In one embodiment, the secondary low purge controller 7020 may include a pressure sensor that is configured to communicate with one or more processors 7062. In one embodiment, the pressure sensor is configured to measure a purge gas pressure in a purge chamber 7054 and send pressure data, which indicate the purge gas pressure in the purge chamber 7054, one or more processors 7062. In one embodiment, one or more processors 7062 is configured to receive pressure data, comparing the pressure data with a predetermined pressure value and for generating excessive pressure signal when the pressure data exceeds a predetermined pressure value of 0.5 lb / sq. inch. In one embodiment of the invention, based on the overpressure signal, the purge and check system 7100 may be configured to open the structure of the exhaust valve to release pressure in the purge chamber 7054 until the measured pressure drops below a predetermined pressure value. In one embodiment of the invention, based on the overpressure signal, the purge and check system 7100 may be configured to transmit communication signals to an external welding system to terminate the welding procedure.

[00992] In one embodiment of the invention, communication signals are sent to the halyard that the proper level of purge gas has been reached and that the welding procedure can begin. In one embodiment of the invention, the operator instructs the external welding system 7500 to begin the execution of the welding procedure. In one embodiment of the invention, one or more processors 7062 automatically sends instructions to an external welding system 7500 to begin a welding procedure.

[00993] In one embodiment, the electronic purge module 7032, together with the electronic module of the front section 7036 and the electronic module of the central section 7040, are configured to use one or more measurement sensors 7042 to measure the clearance and the junction of the weld at a small distance in front of that where the 7500 external welding system is currently welding. In one embodiment of the invention, the verification data may be transmitted in real time by a measuring sensor 7042 to one or more processors 7062 that use this verification data to send updated welding parameters to an external welding system 7500.

[00994] In one embodiment, the external welding system 7500 is configured to transmit position information to one or more processors 7062 that transmit this information to the electronic purge module 7032, so that the electronic purge module 7032 can maintain proper pressure in the purge gas chamber and accordingly monitor the position of the measuring sensor 7042.

[00995] In one embodiment of the invention, the welding procedure can be performed in several different ways.

[00996] In one embodiment of the invention, the welding procedure may be performed top down on one side of the pipes, and then top down on the other side of the pipes. In one embodiment, the first welding is completed before the second welding begins. In this situation, the measuring sensor 7042 performs a scan before welding in real time.

[00997] In one embodiment of the invention, a welding procedure may be performed from top to bottom on each side of the pipe, wherein the second welding starts before the second welding is completed. In one embodiment of the invention, the measuring sensor 7042 scans the distance in front of the location of one welding faster than the welding machine moves, and then quickly changes position and switches to another welding to scan it. In one embodiment of the invention, the measurement sensor 7042 may switch between two weld points until the first weld is completed.

[00998] In one embodiment of the invention, the welding procedure can be performed along the entire pipe around in a single pass, with the measuring sensor 7042 scanning at a small distance in front of the welding site.

[00999] In one embodiment, once the welding is completed, the swivel hub 7012 continues to rotate, while the electronic purge module 7032 checks the progress of welding using the measurement sensor 7042 and camera 7044. In one embodiment of the invention, welding test data is communicated to one or more processors 7062.

[001000] In one embodiment, if one or more weld defects are detected in the weld test data, these weld defects can be repaired while the clamps 7050 and 7052 are still in the desired position and the purge gas chamber 7054 is still full inert gas.

[001001] In one embodiment of the invention, after the inspection and any repair work is completed and confirmed by the operator, the operator sends to the front section 7036 electronic module and the central section 7040 electronic module a command to turn off the control valves of the front and rear clips 7056 and 7058, lowering / retracting clamp shoes 7050 and 7052 and deflating seals 7046 and 7048.

[001002] In one embodiment, one or more purge and test system processors 7062 7100 can be operatively coupled to a front purge and test system electronics 7100, an electronic purge module 7032, a central section electronic purge and test system 7100, and an electronic module module 7064 drive.

[001003] In one embodiment, the field system of the present patent application may comprise one or more distributors / nodes / routers configured to transmit data, control signals, and communication signals between one or more processors 5140 or 7062 and one or more electronic modules described in this application.

[001004] During pipeline formation procedures (for example, in offshore or onshore (onshore) applications, one pipe section 1022a or 1022b is connected to another pipe section 1022b or 1022a when welding pipe lashes (a location where two pipe sections are welded together another) by aligning the two opposite ends of the pipe sections with respect to each other and forming a welding joint 1026. Such a welding joint 1026 connects both sections of the pipe 1022a, 1022b at their opposite ends so that the weld full-time connection 1026 provides a tight hydraulic seal and, thus, creates a continuous channel for fluid movement between two connected pipe sections.Each of pipe sections 1022a, 1022b can be quite long (for example, hundreds or thousands of feet, or even up to 1 mile length ), which makes it difficult to ensure internal cooling inside the pipe sections 1022a, 1022b at or near the place of welding of the lashes of the pipeline after the welded joint 1026 has been formed. In particular, the placement of the cooling device, as well as Installing such a device from the inside of the pipe sections 1022a, 1022b for cooling in a weld joint 1026 can be a difficult task.

[001005] The internal cooling system of the present invention provides internal cooling within the pipe sections 1022a, 1022b after the pipe sections are bonded to each other through a welded joint 1026. In one embodiment, the internal cooling system may be an internal heat exchanger, which may be referred to as "IHEX". In one embodiment of the invention, the internal cooling system comprises a cooling section for directly cooling the internal surface sections of the pipe sections 1022A, 1022b, and a control section or controller that is (a) configured to control the components of the cooling section and further performed (a) with the possibility of promoting the mobility of the internal cooling system within the pipe sections 1022a, 1022b. In one embodiment of the invention, the cooling section uses a cooling agent to provide cooling within the pipe sections 1022a, 1022b. In one embodiment, the internal cooling system may also comprise a cooling agent supply section comprising a cooling agent that is supplied to the cooling section during operation of the internal cooling system. In one embodiment of the invention, the internal cooling system of the present patent application comprises a mechanism configured to internally cool the pipe sections 1022a, 1022b after being welded to each other, as well as a mechanism for placing the internal cooling system inside and removing the internal cooling system from the pipe sections 1022a 1022b during the process of forming the pipeline, which leads to a reduction in the time required to cool the pipe sections after heating, as well as to accelerate the process of working at work their stations used for fabrication.

[001006] In FIG. 104 illustrates an exemplary internal cooling system 2010 of the present patent application. In one embodiment of the invention, the internal cooling system 2010 comprises a suitable rigid frame in which the components of the internal cooling system are accommodated, the frame comprising a plurality of longitudinal or longitudinally arranged rods 2019, 2021 made of one or more suitable materials (e.g., metal, such as steel, or other suitable rigid and durable materials), and has a suitable configuration that allows the frame to be inserted inside the pipe sections to facilitate internal cooling inside three sections of pipe 1022a, 1022b.

[001007] The first section 2011 of the frame contains one or more supply sources of cooling agent 2012 containing one or more reservoirs (one reservoir is illustrated in FIG. 104) fixed in the first section 2011. The reservoirs of the supply of cooling agent may contain any suitable cooling agent, including, but not limited to, water and a cryogenic liquid, such as liquid argon or liquid nitrogen, etc. The second cooling section 2016 is fixed in an intermediate position of the frame next to the first section 2011 and communicates with the power supply of the coolant 2012 through a suitable valve design 2014 (for example, illustrated in Fig. 104 as one or more valves, regulators, pipe assemblies, etc. ), which facilitates the supply of the cooling agent from the supply source of the cooling agent 2012 to the exhaust nozzles 2007 of the cooling section 2016 at one or more suitable pressure and / or flow rates.

[001008] The third frame section 2018 is located adjacent to the cooling section 2016 and comprises a plurality of rods 2021 that form an insulated housing surrounding the controller 2020. The pneumatic and / or electronic drive system 2022 can also be at least partially placed inside the third section 2018 and can comprise one or more rollers 2025 controlled by an engine and / or any other suitable self-propelled structure (s) configured to engage with sections of the inner surface of the pipe sections When the internal cooling system 2010 is located inside of the pipe sections to control movement of the internal cooling system 2010 in forward and rearward directions inside the pipe sections during the procedures described herein. In one embodiment of the invention, the drive system 2022 may be coupled (e.g., via wireline or wireless) to the controller 2020 to facilitate controlling, through the controller 2020, the forward and backward movements of the internal cooling system 2010 during the execution of the procedures (e.g., controlling the motor of the drive system 2022 by controller 2020 controls the rotation of the roller (s) and thus the forward or backward movement of the internal cooling system 2010). In one embodiment of the invention, the drive system 2022 may actually be enclosed within and / or form part of the chassis of the internal cooling system 2010. In one embodiment of the invention, the drive system 2022 may comprise a structure that extends beyond the chassis. In one embodiment of the invention, the drive system 2022 may comprise a suitable cable structure that extends from the internal cooling system 2010 through one or more pipe sections to the open end of the pipe section, where the cable structure is used to facilitate forward and / or backward movement of the internal cooling system 2010 inside pipe sections (for example, by means of a winch structure provided inside the frame of the internal cooling system and / or in a fixed place outside the pipe sections and connected to Yelnia structure). In one embodiment, rollers may also be provided at one end of the internal cooling system 2010 (e.g., rollers 2023 provided on the cable lug of the first section of the chassis 2011, as illustrated in FIG. 104) to increase the mobility of the internal cooling system 2010 in the pipe sections 1022a 1022b.

[001009] In one embodiment of the invention, the controller 2020 may comprise at least one suitable processor that controls the operations of the internal cooling system 2010 by means of suitable control logic commands stored in the controller's memory, as well as electronic signals provided remotely via another user interface located at a suitable distance from the internal cooling system. In one embodiment of the invention, the controller 2020 may be configured to communicate with a remote control device that is controlled by a user (e.g., a computer, manual control device, or any other suitable electronic device) by electronic signals, wherein the electronic signals are transmitted wirelessly or wired between the 2020 controller and the remote control. In one embodiment of the invention, the remote control device is illustrated in FIG. 104 as a computer 2030 (e.g., laptop, notebook, personal digital assistant, smartphone, etc.) that communicates with the controller 2020 via a wireless link (illustrated by a dashed line in FIG. 104). Communication via electronic signals may include two-way communication between the controller 2020 and the remote control device so that the controller 2020 is configured to provide information to the remote control device (such as information about the measured internal temperature and / or other types of measured conditions inside the pipe sections) as well as received control information for performing remote control operations of the internal cooling system 2010.

[001010] In one embodiment of the invention, one or more electronic sensors 2017 may be provided at one or more suitable locations within the frame of the internal cooling system and may communicate (via wired or wireless) with the controller 2020 to provide information about conditions inside pipe sections during procedure execution time. For example, in one embodiment of the invention, one or more electronic sensors 2017 may include one or more temperature sensors (e.g., infrared temperature sensors, RTD temperature sensors, thermocouples, etc.) that may be provided in one or more different places in the first section 2011, cooling section 2016 and / or third section 2018 of the internal cooling system 2010, while the temperature sensors are configured to measure temperature and provide information about such a measured temperature control Yeru 2020 during execution procedures. In one embodiment of the invention, one or more electronic sensors 2017 comprise pressure sensors and / or liquid flow sensors, which may be provided at one or more suitable places in the reservoir (s) 2012 of the source of cooling agent 2012 in the valve structure 2014 and / or near the outlet nozzles 2007 cooling section 2016, while the data of the measured pressure and / or flow rate are provided by such sensors to the controller 2020 during the execution of the procedures.

In one embodiment, one or more cameras 2027 controlled by a controller 2020 (and remotely controlled by a remote control) may also be provided in one or more suitable locations to facilitate viewing inside pipe sections (for example, to determine a suitable location for placement internal cooling system 2010 inside pipe sections 1022a, 1022b during procedures). Exemplary pressure / temperature sensors and / or chambers are generally illustrated at locations 2017 and 2027 in FIG. 104.

[001011] In one embodiment, the internal cooling system 2010 may comprise a suitable power source for providing power to a controller 2020, a drive system 2022, electronic sensors, a valve structure 2014 (for example, to electronically control one or more valves and thus controlling the flow of the cooling agent from the power source of the cooling agent 2012 to the cooling section 2016). In one embodiment of the invention, the power supply may be contained within the frame of the internal cooling system (for example, one or more batteries may be located in the battery pack provided in the third section 2018 or in any other suitable place inside the frame of the internal cooling system). In one embodiment of the invention, the power supply may be located outside of the pipe sections, wherein an electrical cable connects the power supply to the internal cooling system 2010 to provide power to various components of the internal cooling system.

[001012] In one embodiment, the cooling section 2016 may comprise any suitable structure that facilitates cooling by heat exchange with the inside of the weld, as well as other parts of the inner wall of the pipe sections. In one embodiment of the invention, a coolant is supplied from a coolant supply 2012 through a valve section 2014 to a cooling section 2016. In one embodiment of the invention, a cooling section 2016 comprises a plurality of nozzles 2007 located around the outer periphery of the cooling section 2016 to facilitate movement of the cooling stream an agent with a suitable flow rate (controlled by the valve 2014 valve section and nozzle design in the cooling exhaust nozzles section 2007) from the cooling section Denia 2016 toward the inner surfaces of the welded joint and other internal parts of the two connected pipe sections.

[001013] The operation of the internal cooling system 2010 in connection with pipeline welding procedures will now be described with reference to FIG. 105-107. The two pipe sections 1022a, 1022b are axially aligned with each other in preparation for welding the open end of the first pipe section 1022a opposite the open end of the second pipe section 1022b. In one embodiment, both pipe sections 1022a, 1022b can be held in such alignment by clamping the lashes of the pipe (not illustrated in FIGS. 105-107). A suitable pipe lash clamp (e.g., clamps 5302 (located outside the pipe) described elsewhere in this application) may be attached externally to the end ends of pipe sections 1022a, 1022b to hold sections 1022a, 1022b in place with respect to each other during the welding procedure. In one embodiment, the inner clamp of the pipe lashes (e.g., internal clamps 5142, 5144 (located inside the pipe) disclosed elsewhere in this application) can be used to hold the end ends in place during the welding procedure. Both types of pipe lash clamps (external and internal) are known in the art of pipe welding and are therefore not described in more detail herein. After clamping the lashes of the pipe is used to hold the ends of the pipe sections 1022a, 1022b in place relative to each other, a welding joint 1026 is formed at the welding location (i.e., at both opposite open ends of the first and second pipe sections). Welding 1026 is made in the manner described above in detail, and may include a weld root pass, a weld hot pass layer, a weld (e) filling pass layer (s), and a weld facing layer to form a proper weld. In one embodiment of the invention, the formation of the welded joint 1026 may include preheating the opposite ends of the first and second pipe sections 1022a, 1022b to a minimum temperature of about 150 ° C. The rest of the welding procedure can lead to an increase in temperature around the welded joint up to a temperature of about 300 ° C. After the welded joint 1026 is formed, the welded joint 1026 usually passes AUT (automatic ultrasonic testing) and / or is checked by a radiographic method, as described elsewhere in this application, to confirm the quality / integrity of the welded joint 1026. In one embodiment of the invention, the weld check AUT may not be performed at temperatures above a range of from about 50 ° C to about 75 ° C (T _max ), where T _max is the highest temperature at which verification can be effectively performed. In addition, the AUT welding test procedure in the pipe manufacturing process must be stopped until the temperature of the weld 1026 drops to a temperature close to such a test temperature range. The internal cooling system of the present invention is configured to remove heat from the weld zone in order to lower the temperature of the pipe weld area to at least an acceptable test temperature AUT (T _max ).

[001014] In one embodiment, after the weld test procedure, the weld joint insulation (FJC) is also applied to the outer portions of pipe sections 1022a, 1022b surrounding the weld joint 1026 to provide an insulating barrier to prevent or minimize corrosion in the weld zones. Such insulation can, as a rule, be effectively applied only at pipe temperatures above the minimum pipe temperature T _min . Therefore, the temperature in the weld zone rises until the temperature of the pipe in the area of welding to be insulated rises again to a temperature of about 220-240 ° C (T _min ), where T _min is the lowest temperature at which the insulation can be effectively applied in the field of insulation.

[001015] After the coating / insulation procedure, the pipe can be wound on a reel for installation in the field. However, at temperatures around T _{min, the reeling} procedure cannot be efficiently performed while maintaining the integrity of the weld. Therefore, the pipe manufacturing procedure can again be stopped until the pipe temperature gradually naturally (relative to the ambient temperature) drops from T _min to an acceptable winding temperature (T _max ), where T _max is the highest / maximum temperature at which the pipe can be effectively wound on a spool. In one embodiment of the invention, the internal cooling system of the present invention is configured to re-remove heat from the weld area to lower the temperature to a maximum temperature of about 50 to about 75 ° C (T _max ) acceptable for efficient winding (pipe winding on a coil). Therefore, the internal cooling system of this application is configured to lower the temperature before the weld check procedure and / or lower the temperature before the winding procedure, in order to minimize the time required to weld, test, isolate and wind the lashes of the pipe segments.

[001016] During the operating period, when the pipe sections 1022a, 1022b are welded together (followed by coating / insulation), the internal cooling system 2010 is loaded into the open end of the pipe section 1022a, as illustrated in FIG. 105. In one embodiment, one or both of the pipe sections 1022a, 1022b may comprise one pipe assembly. In another embodiment, one of the pipe sections 1022a, 1022b may comprise a plurality of pipe assemblies welded together. In one embodiment, when one of the pipe sections 1022A or 1022b contains a plurality of pipe assemblies already welded to each other, it may be desirable to load the internal cooling system 2010 into the pipe section 1022a or 1022b containing one pipe assembly (or the pipe section with the smallest length) to reduce the time required for the internal cooling system 2010 as part of the pipe section to reach the weld position of the pipe lashes. Thus, in one embodiment, the pipe section 1022a may comprise one pipe assembly that is connected to a longer pipe section represented by the pipe section 1022b (for example, two or more pipe assemblies joined by welded joints).

[001017] In one embodiment of the invention, the internal cooling system 2010 is loaded into the open end of the pipe section 1022a (that is, the end that is opposite the open end opposite the open end of the pipe section 1022b, which determines the location of the lash welding of the pipe) so that the first section The 2011 frame of the internal cooling system serves as the front end and, thus, first enters the pipe section 1022a. In one embodiment of the invention, the internal cooling system 2010 is moved (moved with the first section 2011) within the pipe section 1022a to a suitable location near the weld location of the pipe lashes, as illustrated in FIG. 106. In one embodiment of the invention, the controller 2020 (which the user can remotely control) is configured to control the operation of the drive system 2022 (for example, by controlling one or more motors that bring the rollers 2025 into contact with parts of the inner wall of the pipe section 1022a) so that facilitate the advancement of the internal cooling system 2010 within the pipe section 1022a towards the point of welding of the lashes of the pipeline. Once a suitable location near the weld point of the pipe lash has been reached (for example, the location of the internal cooling system, as illustrated in FIG. 106), the controller 2020 can control the drive system 2022 so as to stop further movement of the internal cooling system 2010 until cooling operations will not start. For example, a camera 2027 mounted in a suitable location on the first section 2011 and controlled by a controller 2020 can provide video images to a remote control device so that the user can determine how close the internal cooling system is to weld joint 1026. In one embodiment of the invention, in combination with the video images provided by camera 2027, one or more temperature sensors 2017, suitably placed on the frame of the internal cooling system 2010, measure the internal temperature in the pipe section 1022a and provide such temperature information to the controller 2020. In the case of when one or more measured temperatures reach a threshold (e.g., about 100 ° C or higher), this may indicate that the internal cooling system 2010 has reached a location near the weld of compound 1026. It may also be any other suitable mechanism to provide an appropriate indication locations internal cooling system 2010 1022a pipe section during its movement towards the welding point lashes pipeline.

[001018] After reaching the desired location, which is in close proximity to or near the place of welding of the lashes of the pipeline, a cooling procedure can be performed after the welded joint 1026 has been formed and before the AUT / check was performed (if necessary) radiography. In one embodiment of the invention, a cooling procedure may be performed after the pipe is reheated to apply an external coating, and then (if required) FJC is applied. In one embodiment, when the internal cooling system 2010 reaches a suitable location in the pipe section 1022a that is close to the weld point of the pipe lane, and until the welding procedure is completed, the internal cooling system 2010 is held in position and ready for use for cooling purposes as soon as The welding or reheating procedure will be completed. The cooling procedure is performed by first placing the cooling section 2016 in a suitable place (for example, with respect to weld 1026, as illustrated in FIG. 107). This can be achieved by moving the internal cooling system 2010 from its location, illustrated in FIG. 106 to its location illustrated in FIG. 107, through a controller 2020 (which is controlled by a user through a remote control device) controlling the drive system 2022 until the internal cooling system 2010 is at the desired location. Moving to such a location (for example, as illustrated in Fig. 107) can be achieved based on the video images inside the pipe sections 1022a, 1022b that are provided to the remote control device, while data from the temperature sensor is sent to the remote control device and / or through any other suitable device.

[001019] Upon reaching the desired location within the pipe sections 1022a, 1022b (for example, where the cooling section 2016 is located in close proximity to the welded joint 1026, as illustrated in Fig. 107), a controller 2020 (which can be controlled by the user through a remote control ) controls the operation of the valve structure 2014 (for example, by controlling one or more electronic valves) to facilitate the advancement of the flow of the cooling agent from the coolant supply 2012 when walking pressure and / or flow rate to the cooling section 2016, where the cooling agent flows from nozzles 2007 located in the cooling section 2016 and appropriately oriented so as to direct the flow of the cooling agent from the cooling section 2016 to parts of the inner surface of the walls inside the pipe sections 1022a, 1022b . The temperature sensor (s) monitors the internal temperature of the internal cooling system 2010 inside the pipe sections 1022a, 1022b and provides information about the measured temperature to the controller 2020. When a sufficient temperature is reached inside the pipe sections 1022a, 1022b (measured using a temperature sensor (s), for example, temperature T _max ° C or lower) the controller 2020 can control the valve structure 2014 to stop the flow of the cooling agent into the cooling section 2016.

[001020] In one embodiment, the internal cooling system 2010 can be moved forward or backward by controlling the drive system 2022 through the controller 2020 to provide additional cooling procedures (as necessary and based on measured temperatures inside the pipes) elsewhere along the internal parts the walls of the pipe section 1022a and / or pipe section 1022b. The internal cooling system 2010 may be removed from the connected pipe sections 1022a, 1022b when it has been determined that sufficient cooling has been achieved. For example, the internal cooling system 2010 can be moved in the opposite direction, or backward, by controlling the drive system 2022 through the controller 2020 to move towards the free and open end of the pipe section 1022a so that the third section 2018 first exits the pipe section 1022a. Then another pipe section can be aligned (the internal cooling system can remain inside section 1022a, while the new section is fitted to 1022a) with the free and open end of pipe section 1022a (at this stage connected by welding 1026 to pipe section 1022b) for the formation of the place of welding of the lashes of the pipeline, and then the process is repeated in which the internal cooling system 2010 enters through the free and open end of the additional section of the pipe and moves to the place of welding of the lashes of the pipeline to perform Nia cooling procedures welded joint defined between the pipe sections.

[001021] Although the drive system 2022 illustrated in the embodiment of the invention illustrated in FIG. 104-107, comprises rollers 2025 controlled by an engine system that is controlled by controller 2020, the drive system 2022 for the internal cooling system may also employ any suitable mechanism capable of providing user-controlled movements of the internal cooling system within the pipe sections. For example, one or more cable / winch systems can be applied in which one or more hoists can be provided as part of an internal cooling system and / or located at one or more reference points that are external to the pipe sections. A cable runs between each winch and the connection point (either in the internal cooling system or at the connection point outside the pipe sections) in such a way as to facilitate the placement of the internal cooling system inside and / or the output of the internal cooling system from the pipe sections during the procedures.

[001022] It should be noted that the procedures described above with respect to the internal cooling system can be performed for any type of pipe lash welding between pipe sections in the pipe system. For example, an internal cooling system can be used to create pipelines in marine, underwater applications, as well as in basic applications. In one embodiment, the internal cooling system 2010 can be used for a sequence of welding lashes of a pipe using a reel (as illustrated in the described embodiment with reference to FIG. 6) and a sequence of welding using a barge (as illustrated in the described embodiment with reference to FIG. . 7).

[001023] In a general application, pipe sections from 40 feet (12 meters) to 80 feet (24 meters) in length are welded together to form long sections of pipe lashes. In scenarios in which a halyard may be required to control movement procedures and / or other procedures in connection with the internal cooling system, the detachable cable may be at least 240 feet (72 meters) long. The procedure for loading the internal cooling system into the pipe section and moving the internal cooling system to the cooling position after the welding procedure (with optional AUT / X-ray welding inspection and coating / insulation / FJC application) are carried out similarly to the previously described procedures with reference to FIG. 104-107.

[001024] In FIG. 108, an internal cooling system 2010-1 is illustrated in accordance with another embodiment of the invention of the present patent application. The internal cooling system 2010-1 is similar to the above described embodiments of the invention, except for the differences that will be indicated below. In one embodiment of the invention, the internal cooling system 2010-1 is configured to connect to the inner lash clip of the pipe 2060 in the end section 2024 of the third frame section 2018 of the internal cooling system 2010-1. In one embodiment, the inner lash clip of the pipe 2060 comprises a frame 2062 with a suitable configuration that allows the clip of the lashes of the pipe 2060 to be inserted into the pipe section (for example, pipe sections 1022a and 1022b), and comprises a section 2064 that is capable of aligning and holding two open and end ends of the pipe sections 1022a, 1022b at the place of welding of the lashes of the pipeline (for example, by expanding with the formation of frictional engagement with sections of the inner surface of the walls of the pipe sections at their end ontsah when lashes pipe clamp 2060 suitably located within the pipe sections 1022a and 1022b). In one embodiment, section 2064 and clamp 60 correspond to portions of internal welding system 5004 having a first pipe clamp 5142 and a second pipe clamp 5144. In one embodiment of the invention, a connecting member 2080 (eg, a rod or spring member) is configured to connect the end 2066 clamp lashes of the pipeline 2060 with the end section 2024 of the frame of the internal cooling system 2010-1.

[001025] In one embodiment, the internal cooling system 2010-1 may be a trailer for clamping the lashes of the pipe 2060. For example, a connecting clip 2060 with an attached internal cooling system 2010-1 (via a connecting member 2080) may be inserted at its end 2065 (i.e., the end of the carcass, which is opposite the end of the carcass 2066, which is connected to the internal cooling system 2010-1 through the connecting element 2080) to the pipe section when moving the clamp of the lashes of the pipe 2060 inside the pipe section also causes a corresponding movement of the internal cooling system in pipe section 2010-1. In one embodiment of the invention, the internal cooling system 2010-1 can be inserted through its first section of the frame 2011 into the pipe section, and then moved to the desired position so as to bring the clamp of the lashes of the pipe 2060 to the corresponding alignment with the location of the welding of the lashes of the pipe between both aligned pipe sections. In one embodiment, the drive system 2022 of the internal cooling system 2010-1 may be used to move the combined lash clamp structure of the pipe 2060 / internal cooling system 2010-1 to a suitable location within the pipe sections or, alternatively, any other suitable drive mechanism may also be used to move such a structure inside pipe sections (for example, one or more cable / winch systems).

[001026] In one embodiment, the lash clamp of the pipe 2060 holds the ends of the pipe sections 1022a, 1022b together until a welded joint 1026 is formed. In one embodiment, the section 2064 and the clip 60 correspond to sections in an internal welding system 5004 having a first pipe clamp 5142 and the second pipe clamp 5144. After forming the weld joint 1026 (and, if necessary, forming a coating), the clamp of the lashes of the pipe 2060 can be disconnected from the sections of the inner surface of the pipe walls of the pipe sections to facilitate it moving internal cooling system 2010-1 at a suitable location (e.g., so that the cooling section 2016 is aligned with the weld) to initiate the internal cooling within the pipe sections 1022a, 1022b.

[001027] In FIG. 109, another embodiment of the invention is disclosed for connecting an internal cooling system to an internal clamp of pipe lashes, in which a longer connecting element 2082 (for example, an elongated shaft) is provided for connecting an internal cooling system 2010-1 to a clip of lashes of a pipe 2060. In one embodiment of the invention the connecting element 2082 has a larger longitudinal dimension than the connecting element 2080 (illustrated in FIG. 108), which minimizes the heating of the internal cooling system 2010-1 during the welding procedure time (due to the greater separation distance between the inner cooling duct and clip lashes).

[001028] In one embodiment, the procedure comprises loading the lash clamp of the pipe 2060 together with the internal cooling system 2010-1 into one of the pipe sections and aligned so that the clamp of the lashes of the pipe 2060 holds both ends of the pipe sections facing each other at the weld point lashes of the pipeline. After some welding procedures have been completed (e.g., welding of the root of the seam and the hot passage), the clamp of the lashes of the pipe 2060 with the internal cooling system 2010-1 can be moved together and further from the point of welding of the lashes of the pipe to avoid further exposure to heating due to the ongoing process welding required to complete the weld. In one embodiment of the invention, if the connecting element is of sufficient length (for example, the connecting element 2082 in FIG. 109), the lash clip of the pipe 2060 with the internal cooling system 2010-1 can be moved so that the lash clip of the pipe is on one side, and the internal cooling system was located on the other hand from the place of welding of the lashes of the pipeline (only on the condition that the connecting element 2082 is located directly below or in the immediate vicinity of the place of welding fly the pipeline). After completing welding and checking (s) the AUT / X-ray method (if required), and after applying any coating / insulation / FJC, the lash clamp of piping 2060 with internal cooling system 2010-1 can be moved to the desired location so that the cooling section 2016 of the internal cooling system was in close proximity to the welded joint and cooling procedures could be performed (for example, by a method similar to that described previously with respect to an embodiment of the invention, illustrate fig. 104-107).

[001029] In one embodiment of the invention, the cooling section of the internal cooling system can be implemented with any type of cooling structure for quick and / or efficient cooling of the pipe sections at the site of the newly formed welded joint and, therefore, is not limited to the exemplary embodiments of the invention, illustrated in FIG. 104-109. For example, in one embodiment of the invention, a cooling structure integrated as part of an internal cooling system may include, without limitation, cooling fans (e.g., fans 2122, illustrated and described below) that force air flows through portions of the inner surface of the pipe sections and / or through fins of a heat exchanger or other cooling elements of an internal cooling system, releasing liquid and / or gaseous fluids (e.g. cryogenic fluids, liquids, air), etc. the corresponding pressures and temperatures from the nozzles 2007 or 2318 of the cooling section 2016 or 2316 towards the sections of the inner surface of the pipe sections using cooling fluids in a closed recirculation loop (for example, pump 2212, manifold 220 and ribbed elements 2218, as illustrated in Fig. 111A and 111B) and through the heat exchange design of the cooling section, using thermoelectric cooling (for example, through Peltier devices in direct contact with sections of the inner surface of the walls of the pipe sections ) etc.

[001030] In FIG. 110A and 110B illustrate an internal cooling system 2110 in accordance with another embodiment of the invention in the present patent application. Internal cooling system 2110 is similar to the previously described embodiments of the invention, except for the differences that will be indicated below. In one embodiment of the invention, the cooling section 2116 of the internal cooling system 2110 comprises a heat sink that comprises a plurality of ribbed elements 2118 that are perimeter and radially extending outward from the central support element 2120 of the cooling section 2116, and contains curved portions of the outer surface that correspond to curved the inner surface portions of the pipe sections to which the ribs 2118 extend. In one embodiment of the invention, each ribbed element 2118 comprises a plurality sections of thin material extending from the location of the central heat sink of the cooling section 2116 radially outward towards the curved section of the end wall of the rib element 2118. In one embodiment, the ribbed elements 2118 are made of a material having appropriate thermal conductivity (eg, copper, aluminum, and t etc.) in order to facilitate a high rate of heat transfer from the inner wall sections of the pipe sections 1022a, 1022b to the heat sink of the cooling section 2116. In one embodiment of the invention ebristye elements 2118 comprise open channels 2120 defined between adjacent sections of a thin material, the open channels 2120 extend longitudinally through the fin parts. In one embodiment, electric fans 2122 may be mounted on a central support member 2123 in close proximity to the ends of the ribbed elements 2118 and aligned with the ribbed channels 2120. In one embodiment, the electric fans 2122 allow air to flow through the ribbed channels 2120 to cool the ribbed elements 2118 and, thus, cause heat to move through convective air flows from the heat sink of the cooling section 2116. In one embodiment, real ation invention fans 2122 are in communication (e.g., via a wired or wireless link) to the controller 2020 to facilitate selective operation of fans 2122 during cooling procedures. In one embodiment of the invention, each fan 2122 may be configured to operate at a variable speed to selectively control the fan speed and the corresponding air flow rate through the ribbed elements 2118 in different ways and if necessary during the cooling procedure.

[001031] The operation procedure of the internal cooling system 2110 illustrated in FIG. 110A and 110B are similar to the previously described procedure for the embodiment of the invention illustrated in FIG. 104-107 in connection with the placement of the internal cooling system during the welding procedure and positioning for cooling after completion of the welding procedures. During cooling, fans 2122 may be actuated to provide cooling air flow from one or more desired flow rates through channels 2120 of ribbed elements 2118. In one embodiment of the invention, ribbed elements 2118 draw heat from sections of the inner surface of the walls of pipe sections 1022a, 1022b ( including the welded joint 1026) and direct it to the central supporting element 2123 of the cooling section 2116, and forced air flows provided by the fans 2122 take away heat from rib elements 2118, thereby providing cooling of the pipe sections 1022a, 1022b at the location of the cooling section 2116. As described in previous embodiments of the invention, the temperature sensors of the internal cooling system can provide information about the measured temperature to the controller 2020, and such information about the measured temperature can be used to control the operation of fans 2122 (including changing the rotational speed of one or more fans 2122) during the cooling procedure. When the desired temperature is reached in the pipe sections 1022a, 1022b, the fans 2122 can be turned off via the controller 2020. In one embodiment of the invention, the internal cooling system 2110 can be additionally moved to different locations as necessary inside the pipe sections 1022a, 1022b for cooling at different places .

[001032] In FIG. 111A and 111B illustrate an internal cooling system 2210 in accordance with another embodiment of the invention in the present patent application. Internal cooling system 2210 is similar to the above-described embodiments of the invention, except for the differences that will be indicated below. In one embodiment, the internal cooling system 2210 comprises a cooling section 2216, which comprises a series of ribbed elements 2218 located along the periphery and extending radially outward from the central support element 2223 of the cooling section 2216, while the ribbed elements 2218 have the same external shape or profile, as well as the ribbed elements 2118 of the embodiment of the invention illustrated in FIG. 110A and 110V. In one embodiment, the ribbed elements 2218 may also be made of a material having appropriate thermal conductivity (e.g., aluminum or copper). However, each ribbed element 2218 may have a hollow and sealed inner layer to facilitate the movement of the coolant through the ribbed element 2218. In one embodiment, each ribbed element 2218 includes an inlet at one end and an outlet at the other end, and a suitable structure is provided pipes to facilitate the operation of the recirculation loop of the coolant stream from the pump 2212 to the rib element 2218, while the cooling agent flows through the rib element 2218 and the return of the pump 2212 may be any suitable type of coolant (e.g., water, a cryogenic liquid such as liquid nitrogen or liquid argon, etc.).

[001033] In one embodiment, a pump 2212 (illustrated in FIG. 111A) may be located outside of pipe sections 1022a, 1022b, with feed and return channels 2214 passing between pump 2212 and manifold structure 2220 (illustrated in FIG. 111B) . In one embodiment of the invention, the design of manifold 2220 comprises a plurality of pipe connections that are connected to the inlets and outlets of the ribbed elements 2218. Thus, the cooling section 2216 facilitates heat exchange between the circulating coolant stream within the ribbed elements 2218 and the portions of the inner wall surface of the pipe sections 1022a 1022b (for example, in or near weld 1026) during cooling procedures.

[001034] In one embodiment, the pump 2212 can be controlled (via a suitable wired or wireless communication line) through the controller of the internal cooling system 2210. Alternatively, the pump 2212 can be controlled externally (since it is easily accessible to the user). The coolant flow controlled by pump 2212 can be controlled based on the measured temperature information provided by one or more temperature sensors in the internal cooling system 2210. After reaching the desired temperature in pipe sections 1022a, 1022b, the pump can be deactivated or turned off to stop the recirculation flow refrigerant and facilitate the movement of the internal cooling system 2210 inside the pipe sections 1022a, 1022b.

[001035] In FIG. 112A and 112B illustrate an internal cooling system 2310 in accordance with another embodiment of the invention in the present patent application. The internal cooling system 2310 is similar to the above described embodiments of the invention, except for the differences that will be indicated below. In one embodiment, the internal cooling system 2310 comprises a cooling section 2316 that has a plurality of spray nozzles 2318 arranged around a central support element 2323 of the cooling section 2316. In one embodiment, the spray nozzles 2318 are typically arranged in linear rows extending in longitudinally along the central support element 2323. A suitable pipe structure is provided at each end of each linear row of spray nozzles 2318, where Design of pipes connected to the manifold 2320. The manifold 2320 is coupled via fluid conduit 2314 with a coolant pump 2312 provided outside or beyond the pipe sections. In one embodiment of the invention, the operation of the cooling agent pump 2312 provides a flow of cooling agent (e.g., water and cryogenic liquid, such as liquid nitrogen or liquid argon, etc.) from a source of cooling agent through a manifold 2320 and from spray nozzles 2318 in the direction to the sections of the inner surface of the pipe sections 1022a, 1022b (including at the weld 1026). Although the embodiment of the invention illustrated in FIG. 112A and 112B, shows a pump 2312 located outside the pipe sections 1022a, 1022b, it should be noted that the cooling section 2316 with the alignment of the spray nozzles 318 can also be easily performed for the embodiment of the invention illustrated in FIG. 104-107 (that is, when the manifold 2320 and the spray nozzles 2318 receive a cooling agent from a source of cooling agent 2012). The cooling procedures of the internal cooling system 2310 can be carried out in a manner similar to that described in connection with the previous embodiments of the invention, in which the pump 2312 can be controlled through the controller of the internal cooling system 2310 and / or from the outside, where the flow of the cooling agent can be directed on the basis of information about the measured temperature provided by temperature sensors located on the internal cooling system 2310.

[001036] Thus, the internal cooling system of the present patent application is configured to provide improvements for pipeline welding procedures, including improving the cooling of connected pipe sections after forming welded joints by providing internally controlled cooling in the pipe sections and reducing production time (since cooling may occur faster and more efficiently; you can increase the number of welded joints between pipe sections that can occur over a certain period of time ) In addition, the number of workstations associated with welding procedures and the resources associated with such welding procedures can be reduced. For example, the working space needed to weld the pipe sections to each other can be reduced, and this can be especially practical in scenarios in which the working space is limited (for example, on barges or in relation to water tanks).

[001037] In one embodiment, a method is provided for welding pairs of insulated pipes (for example, pipes 1022a, 1022b, as illustrated in FIG. 113). As illustrated in FIG. 113, each pipe 1022a, 1022b includes an inner metal portion of the pipe 5244 surrounded by insulating material 5246. In one embodiment, the end portions 5248, 5250 of the pipes 1022a, 1022b to be welded have an exposed or exposed inner portion of the metal pipe 5244.

[001038] In one embodiment, with reference to FIG. 113-34 the method comprises aligning the open ends of metal pipes 5248, 5250 for welding, welding together the open ends of metal pipes 5248, 5250, heating the open end sections 5248, 5250 of the welded pipes 1022a, 1022b, applying an insulator 5246 to the heated open end sections 5248, 5250 of the welded pipes so that the insulator 5246A (as illustrated in FIG. 118) engages with the outer surface 5254 of the inner part of the metal pipe 5244, thereby insulating the previously opened end parts 5248, 5250 of the pipes 1022a, 1022b, and ix cooling energy within the tubes 1022a, 1022b to the inner surface 5130a, 5130b metal pipes 1022a, 1022b.

[001039] In one embodiment, the application of cooling energy inside the pipes to the inner surface of the metal pipes is performed after applying the insulator. In one embodiment of the invention, the method also comprises performing a pipeline deployment procedure. In one embodiment of the invention, the use of cooling energy shortens the waiting time between applying the insulator and performing the pipeline deployment procedure. In one embodiment of the invention, the pipeline deployment procedure is a procedure for winding pipes onto a spool. In one embodiment, the pipeline deployment procedure is an S-shaped pipe-laying procedure. In one embodiment, a pipeline deployment procedure is a pipeline lowering procedure. In one embodiment, the pipeline deployment procedure is described with respect to FIG. 1B of the present patent application.

[001040] In one embodiment, platforms 5330 (as illustrated in FIGS. 10A and 10B) or platforms 6010A and 6010B (as illustrated in FIG. 73) are used to carry and move pipes 1022a and 1022b and to provide the open end of metal pipe 5248 inlet pipe 1022a for the open end of the metal pipe 5250 of the pipe 1022b.

[001083] In one embodiment, every second element 6590 is designed and configured to connect to a heat exchange element 6580 at one end and to a first heat exchange element 6588 at the other end. In one embodiment, each first element 6588 is designed and configured to connect to a second element 6590 at one end and to a portion of the piston 6586 (or an element moved by the piston 6586) at the other end.

[001084] In one embodiment, the second element 6590 is designed and configured to be positioned in the radially extending hole 6592 in the (fixed) frame element 6594 so that the radially extending hole 6592 facilitates radial movement (eg, radial upward movement and down) the second element 6590 located therein.

[001085] In one embodiment, the piston 6586 is axially movable in the cylinder 6584. In one embodiment, the first members 6588 are moved axially by a reciprocating piston 6586, for example, driven by pressure (hydraulic or pneumatic ) fluid inside cylinder 6584.

[001086] The heat exchange elements 6580 move from their retracted positions (as illustrated in FIG. 122), where the contact surfaces 6572 of the heat exchange elements 6580 do not contact the inner surfaces 5130a, 5132a of the pipes 1022a, 1022b to their extended positions (as illustrated in FIG. 201 and 121), where the contact surfaces 6572 of the heat exchange elements 6580 are adapted to contact the inner surfaces 5130a, 5132a of the pipes 1022a, 1022b by actuating the cylinder 6584 so that the piston 6586 moves axially in the cylinder 6584. Compressed air entering the bore 6503 causes the piston 6586 to move the heat exchange elements 6580 to their extended positions.

[001087] In one embodiment, the axial movement of the piston 6586 is converted to radial movements of the second elements 6590 through the first elements 6588. Thus, the radial contact forces are generated by the liquid pressure of compressed air acting on the piston 6586. The piston 6586 drives the first elements 6588, which transform the axial movement of the piston 6586 into the radial movement of the second elements 6590. Since each heat exchanger element 6580 is functionally connected to the second elements 6590, the radial movements the second elements 6590 lead to radial movements of the heat exchange element 6580 between its extended and retracted positions.

[001088] In one embodiment of the invention, the cylinder size, the applied fluid pressure and the sizes of the various components of the drive mechanism 6582 can be changed to control the extension and retraction of the heat exchange elements 6580.

[001089] In one embodiment of the invention, as illustrated in FIG. 123, the cooling system 6500 may include a liquid nozzle 6562 configured to apply coolant to the inner surface 5130a, 5130b of the welded pipes 1022a, 1022b to remove heat from the welded pipes 1022a, 1022b. In one embodiment, the fluid nozzle 6562 is a water nozzle that inflates / sprays water on the inner surface 5130a, 5132a of the pipe 1022a, 1022b to facilitate cooling of the welded pipes 1022a, 1022b.

[001090] In one embodiment, the heat exchanger 6502 may comprise a plurality of liquid nozzles 6562 that are arranged circumferentially and axially (along the axis of the pipe) at locations spaced apart from each other. In one embodiment, each fluid nozzle 6562 is configured to receive coolant from a source of coolant 6564 through a coolant supply line 6566 and through one or more valves. In one embodiment of the invention, the cooling agent is a gas or liquid. In one embodiment of the invention, the obtained cooling agent is sprayed with liquid nozzles 6562 onto the inner surface 5130a, 5132a of the welded pipes 1022a, 1022b to remove heat from the welded pipes 1022a, 1022b.

[001091] In FIG. 124 and 125, a heat exchange element 6574 is illustrated, which is extendable, for example, by a drive mechanism 6582, illustrated and described with reference to FIG. 120-122. In one embodiment of the invention, the contact surface 6572 of the heat exchange element or fins 6574, when the heat exchange element 6574 is in the extended position, is configured to contact the inner surface 5130a, 5132a of the welded pipes 1022a, 1022b to remove heat from the welded pipes 1022a, 1022b. In one embodiment of the invention, the heat exchanger may comprise a plurality of such heat exchange elements or fins 6574 that are circumferentially spaced apart from one another and which can be extended and retracted by a drive mechanism (e.g., pneumatic or otherwise). In one embodiment of the invention, the heat exchange element or fin 6574 may comprise a plurality of fluid (air) channels 6576 that are configured to allow fluid to pass through them. In one embodiment, the channels 6576 may extend radially and be spaced apart from each other in a circle.

[001092] With reference to FIG. 126-128, in one embodiment, the cooling system 6500 may include a drive system 6602. In one embodiment, the drive system 6602 may include a cable structure 6604 that extends from the internal cooler system 6500 through one or more pipes 1022a, 1022b to the open end 6606 pipes 1022a. In one embodiment of the invention, the design of cable 6604 is used to facilitate movement of the internal cooler system 6500 in pipes 1022a, 1022b.

[001093] In one embodiment, one or more cable / winch systems 6608 and 6604 can be implemented, in which one or more winch 6608 can be provided as part of the internal cooler system 6500 and / or are located at one or more reference points (for example 6610), which are external to the pipes 1022a, 1022b. In one embodiment of the invention, a winch structure may be provided in the internal cooler system 6500.

[001094] For example, in one embodiment of the invention, a winch 6608 is provided in a support position 6610 outside the pipes 1022a, 1022b, and is connected to the cable structure 6604. That is, with reference to FIG. 127 and 128, one end 6612 of the cable structure 6604 is connected to the structure of the winch 6608, and the other end 6614 of the cable structure 6604 is connected to the element 6616 of the front frame 6618 of the cooler system 6500. This configuration of the cable structure 6604 and the structure of the winch 6608 facilitates forward movement of the internal cooler system 6500 in pipes 1022a, 1022b.

[001095] In one embodiment, another cable structure may be coupled to the rear frame member 6620 6622 (as illustrated in FIG. 119) of the cooler system 6500 to facilitate backward movement of the internal cooler system 6500 in pipes 1022a, 1022b. This cable design can be controlled by another winch design (for example, provided at a support site at the back or outside of pipes 1022a, 1022b) to facilitate reverse movement of the internal cooler system 6500 in pipe sections 1022a, 1022b.

[001096] Thus, the design of cable 6604 extends between the winch 6608 and the connection point (either in the internal cooler system 6500 or at the connection point externally with respect to the pipes 1022a, 1022b) to facilitate placement of the internal cooler system 6500 inside and / or out internal cooler system 6500 from pipes 1022a, 1022b during procedures.

[001097] In one embodiment of the invention, as illustrated in FIG. 129, the cooling system 6500 may comprise a plurality of rollers 6530 configured to interact with the inner surface 5130, 5132 of one or more pipes 1022a, 1022b and a drive motor 6532 configured to cause the rollers 6530 to move to move the chassis assembly 6503 (including the front frame 6618, central frame 6634 and drive frame 6622) of the cooler system 6500.

[001098] In one embodiment, the electronic cooler module 6528 is configured to control the operation of the drive system 6602 (for example, by controlling one or more motors 6532 (which bring the rollers 6530 into contact with the interior portions of the pipe walls) to facilitate the advancement of the internal cooler system 2010 inside the pipe 1022a toward the weld point. In one embodiment, the electronic cooler module 6528 of the internal cooler system 6500 is configured to communicate with one or more percent essors 5140 and one or more other processors or electronic modules (for example, functionally connected to various welding systems, functionally connected to platforms, clamps or other pipe alignment systems and / or located at a remote location from these systems), as described in this application.

[001099] In the illustrated embodiment, each roller 6530 of the cooler system 6500 is operatively associated with its respective drive motor 6532. That is, four drive motors 6532 are coupled, as illustrated, with four rollers 6330. In another embodiment, two rollers 6530 can be directly connected to two drive motors 6532, and the other two rollers 6530 can be functionally connected to two rollers 6530, which are directly connected to the drive motors 6532.

[001100] In one embodiment of the invention, as illustrated in FIG. 130 and 131, the cooling system 6500 may include a power supply 6526 to provide electric power to the electronic cooler module 6528 of the cooler system 6500, drive system 6602, electronic sensors, valve design (for example, to electronically control one or more valves 6522, and thus control the flow of the cooling agent from the supply source of the cooling agent 6524 to the heat exchanger 6502). In one embodiment of the invention, the power supply 6526 is contained in the frame assembly of the cooler system 6500. In one embodiment of the invention, the power supply 6526 contains a plurality of battery cells or battery compartments that are contained in the rear frame 6622 of the cooler system 6500. In one embodiment, seven are illustrated batteries. In one embodiment, the number of batteries may vary. In one embodiment, the number of batteries may depend on the type of heat exchanger used and / or other energy requirements of the cooler system 6500. In the illustrated embodiment, the power supply 6526 is illustrated in a cooler system having a thermoelectric heat exchanger. However, it is contemplated that the 6526 power supply may be used with chiller systems having any type of heat exchanger, as described herein.

[001101] In one embodiment, one or more battery cells carried by the chassis of the cooler system 6500 is configured to power a drive motor 6532 and a brake system belonging to the cooler system 6500. In one embodiment, one or more battery cells carried by the chassis of the system cooler 6500, configured to power cooler 6502 cooler system 6500.

[001102] In one embodiment of the invention, as illustrated in FIG. 130 and 132, the heat exchanger 6502 of the cooler system 6500 may be a thermoelectric heat exchanger 6502. For example, the thermoelectric heat exchanger may be a Peltier device.

[001103] In one embodiment, the thermoelectric heat exchanger 6502 may have a plurality of chassis elements 6538 located at circumferentially spaced locations on a shaft member 6542 of the cooler system 6500. In the illustrated embodiment, six chassis elements 6538 are illustrated. In one embodiment, the number of cells frame 6538 may vary. In one embodiment, each frame element 6538 may have a plurality of thermoelectric heat transfer elements 6544 located thereon. In the illustrated embodiment, six thermoelectric heat transfer elements 6544 are located on each frame element 6538. In one embodiment, the number of thermoelectric heat transfer elements 6544 located on each element frame 6538 may vary.

[001104] In one embodiment, frame members 6538 may be supported on shaft member 6542 of cooler system 6500 through support members 6540 (eg, two). In one embodiment of the invention, the support members 6540 can be extended and retracted by a drive mechanism. In one embodiment of the invention, the drive mechanism is capable of extending the support members 6540 so that the frame members 6538 and the thermoelectric elements 6544 located thereon are in contact with the inner surface 5130a, 5132a of the welded pipes to remove heat from the welded pipes 1022a, 1022b. In one embodiment of the invention, the drive mechanism may be pneumatically controlled or may be controlled in any other way that would be understood by a person skilled in the art.

[001105] In one embodiment of the invention, as illustrated in FIG. 133, the heat exchanger 6502 of the cooler system 6500 may be a supercharger 6505 configured to blow cooling gas onto the inner surface 5130a, 5132a of the welded pipes 1022a, 1022b to remove heat from the welded pipes 1022a, 1022b. In one embodiment of the invention, the supercharger blows air onto the inner surface 5130a, 5132a of the pipe 1022a, 1022b to facilitate cooling of the welded pipes 1022a, 1022b. In one embodiment, supercharger 6505 may comprise a chassis member 6550 having multiple openings 6552 on it. In one embodiment, chassis member 6550 is designed and configured to receive air from an outlet of a compressed air source 6554 (e.g., under high pressure). In one embodiment of the invention, the frame member 6550 is designed and configured to receive air from an exhaust ventilator driven by an engine. In one embodiment of the invention, the openings 6552 formed on the chassis member 6550 are configured to function as exhaust openings for supplying received air to the inner surface 5130a, 5132a of the welded pipes to remove heat from the welded pipes 1022a, 1022b.

[001106] In one embodiment of the invention, as illustrated in FIG. 134, a camera 6556 mounted at a CL location on the first section 6558 and controlled by an electronic cooler module 6528 can provide video images to the remote control so that the user can determine how close the internal cooling system 6500 is to weld 1026.

[001107] In one embodiment of the invention, as illustrated in FIG. 135 and 136, the cooling system 6500 comprises a supercharger 6650 configured to blow cooling gas onto the inner surface 5130a, 5132a of the welded pipes 1022a, 1022b to remove heat from the welded pipes 1022a, 1022b. In one embodiment, supercharger 6505 comprises a fan. In one embodiment, the design, location, and operation of supercharger 6505 may be similar to the functions of fan 2122, as described in detail elsewhere in this application.

[001108] In one embodiment, with reference to FIG. 135 and 136, the heat exchange elements 6580 are moved from their retracted positions (as illustrated in FIG. 136), in which the contact surfaces 6572 of the heat exchange elements 6580 do not contact the inner surfaces 5130a, 5132a of the pipes 1022a, 1022b to their extended positions, in which the contact surfaces 6572 of the heat exchange elements 6580 are arranged to contact the inner surfaces 5130a, 5132a of the pipes 1022a, 1022b by controlling the drive mechanism 6664.

[001109] In one embodiment, the actuator 6664 may be a linear actuator. In one embodiment of the invention, the drive mechanism 6664 may comprise an engine 6652, a lead screw 6654, a screw nut for screw transmission 6656, a plurality of first elements 6664 and a plurality of second elements 6666. In one embodiment, the number of first and second elements may depend on the amount of heat exchanger element 6580 used. In one embodiment of the invention, every second element 6666 is designed and configured to connect to a heat exchange element 6580 at one end and to the first element 6664 on the other th end. In one embodiment of the invention, each first element 6664 is designed and configured to connect to a second element 6666 at one end and to an element 6662 moved by an engine 6652 at the other end.

[001110] In one embodiment, the engine 6652 is configured (for example, mechanically coupled) to rotate the lead screw 6654. In one embodiment, the engine 6652 is configured to rotate either in a clockwise or counterclockwise direction so that cause the raising or lowering of the heat transfer elements 6580, actually perpendicular to the pipe axis of the pipes 1022a, 1022b. In one embodiment of the invention, the motor 6652 is configured to be directly connected to rotate the lead screw 6654. In another embodiment, the engine 6652 is configured to be indirectly connected, for example, by a series of gears or gearbox, to rotate the lead screw 6654.

[001111] In one embodiment of the invention, the lead screw 6654 comprises a thread machined on its outer surface and extending along its length. In one embodiment, the screw nut 6656 is designed and threaded on a lead screw 5514 and contains additional threads machined on its inner surface.

[001112] In one embodiment of the invention, the screw nut 6656 is configured to lock with the portion of the element 6662 so that the screw nut of the screw gear 6656 is prevented from rotating with the lead screw 6654. That is, the nut of the screw gear 6656 is kept from rotating together with the lead screw 6654 therefore, the screw drive nut 6656 is configured to move up and down the lead screw 6654. In one embodiment of the invention, the screw nut 6656 is locked and located in the hole of the element 6662. In one embodiment of the invention, the lead screw 5514 is configured to extend through a hole of a locked nut of a helical gear 5516.

[001113] The operation of the drive mechanism 6664 is discussed in detail below. When the lead screw 6654 is rotated by the 6652 engine, the screw drive nut 6656 is threaded. In one embodiment of the invention, the direction of motion of the screw nut 6656 depends on the direction of rotation of the lead screw 6654 by the motor 6652. When the screw nut 6656 is locked in the hole of the element 6662, the element 6662 is configured to move the lead screw 6654 together with the nut of the screw gear 6656. That is element 6662 moves linearly (from right to left or left to right) when the motor 6652 rotates. In addition, when element 6662 is connected to the first elements 6658, the movement of element 6662 causes the first x elements 6658. Since the second elements 6660 are connected to the first elements 6658, the movement of the first elements 6658 causes a radial (up or down) movement of the second elements 6660. That is, the linear movement of the element 6662 is converted into radial (up or down) movement of the second elements 6660 through the first Elements 6658.

[001114] When the heat exchange element 6580 is connected to the second elements 6660, radial (up or down) movement of the second elements 6660 causes radial (up or down) movement of the heat exchange element 6580. Thus, the motor 6652 is configured to move the contact surfaces 6572 of the heat exchange elements 6580 outwardly engaged with the inner surface 5130a, 5132a of the metal pipes 1022a, 1022b.

[001115] In one embodiment, the time it takes for the chiller system to cool the pipes (for example, after the coating procedure and before the winding procedure) can range from 90 to 150 minutes.

[001116] Since the cooling system can be used to apply cooling energy to the inner surface of the metal pipes, inside the pipes, the cooling time of the metal pipes can be shortened (for example, compared to the permissible free cooling of the metal pipes or compared to applying a cooling agent on top of the insulating material) . This, for example, can facilitate the cooling of metal pipes after the insulating material is applied to the welded pipe, which must be preheated before applying the weld metal. As a result, the welded pipe can be commissioned or otherwise further processed faster. In particular, after the welded pipe is heated to apply insulating material and the insulator is applied, it should not be subjected to the high loads that may occur during the deployment procedure. For example, in some embodiments of the invention, the welded pipe and its insulation (the insulation of which is applied only after the temperature of the welded pipe rises by heating to a temperature of at least 160 ° C) is intended to be wound on a coil during a winding operation. Such a winding operation is ideally performed only after the welded and insulated metal pipe is cooled to a level below the threshold level (for example, below 50 ° C). The use of an internal cooler can accelerate the achievement of cooling a metal pipe to a level below a threshold level. In another application of the internal cooler system, the pipes are then welded (also before applying the insulator).

[001117] The winding operation is one of a number of deployment procedures that can only be ideally performed after the temperature of the welded pipe drops below a threshold temperature (for example, by operating an internal cooler). Other deployment procedures may include an S-shaped pipe-laying procedure and / or a J-shaped pipe-laying procedure on a pipe-laying barge. The temperature of the welded pipe must be below the threshold temperature before the pipe is immersed in water (for example, sea or ocean).

[001118] Furthermore, in another application, it may be desirable to test welding by an ultrasonic sensor in an ultrasonic monitoring system. The ultrasonic testing station is configured to ideally operate below a threshold temperature (for example, below 80 ° C), which can be achieved faster (after the pipe is heated as a result of the welding operation) using a cooler system. Thus, in one system, the cooler can be used before the operation involving the ultrasonic control system, which will be carried out after welding and before re-heating the pipe for applying insulating material.

[001119] In one embodiment, with reference to FIG. 136A, an ultrasonic testing station 6801 is provided which is configured to test welding between welded metal pipes 1022a, 1022b. In one embodiment of the invention, the cooling system 6500 is configured to facilitate cooling of the metal pipes 1022a, 1022b after welding the pipes 1022a, 1022b and before checking the welding by the ultrasonic testing station 6801.

[001120] In one embodiment of the invention, a temperature sensor (eg, 2017a illustrated in FIGS. 104-109) can be used to detect the temperature of pipe 1022a, 1022b near weld 1026. For example, with reference to FIG. 107, the temperature sensor 2017a is configured to be placed on the internal cooler system and near the weld 1026. In one embodiment of the invention, the temperature sensor 2017a may be located near the heat exchange elements or fins of the internal cooler system to measure the temperature (inner diameter) of the pipe internal surfaces 5130, 5132 1022a, 1022b. In another embodiment, the temperature sensor may be located at ultrasonic testing station 6801. In one embodiment, the temperature sensor may be a contact or non-contact temperature sensor.

[001121] In one embodiment, a temperature sensor 2017a that measures the temperature of pipes 1022a, 1022b may be operatively coupled to one or more processors. In one embodiment, one or more processors send instruction manuals to cooler 6502 based on signals received from temperature sensor 2017a. In one embodiment, one or more processors control the cooler until the sensor 2017a and the processor determine that the temperature of the pipes 1022a, 1022b is below a threshold temperature.

[001122] In one embodiment, one or more processors may be configured to determine that the temperature of the pipe 1022a, 1022b near the weld 1026 is below a predetermined temperature threshold. In one embodiment, the temperature sensor may be configured to detect that the temperature of the pipe 1022a, 1022b near the weld 1026 is below a predetermined temperature threshold.

[001123] In one embodiment, the verification by the ultrasonic inspection station 6801 begins after the temperature sensor 2017a detects that the temperature of the pipe 1022a, 1022b near the weld 1026 is below a predetermined temperature threshold.

[001124] In FIG. 136B illustrates a pipeline deployment method. In FIG. 136C and 136D illustrate schematic views of an S-shaped pipe deployment system and a J-shaped pipe deployment system. In FIG. 136E illustrates barges with an S-shaped pipe and J-shaped.

[001125] In one embodiment of the invention, pipes 1022a, 1022b (eg, about 40 feet or 80 feet in length) are made during the manufacturing process of pipes 6902. In one embodiment of the invention, the manufactured pipes are stored in a pipe storage 6904 before the pipes are sent for further processing, for example, to a barge with S-shaped pipe unwinding 6942 (as illustrated in Fig. 136C), an onshore pipe welding base or barge with a J-shaped pipe laying 6944 (as illustrated in Fig. 136D). In one embodiment of the invention, the pipe storage may comprise a plurality of storage racks.

[001126] In one embodiment, during the onshore tube welding base procedure 6914, fabricated pipe sections are received by the onshore pipe welding base, these pipe sections are connected to the onshore pipe welding base to form long pipe sections, and these long pipe sections are then wound and loaded onto a ship, ship or a barge. In one embodiment of the invention, the onshore pipe welding base may include semi-automatic or automatic welding systems, field coating systems for joints, non-destructive testing and testing systems, storage racks, roller systems and / or other pipe processing equipment for manufacturing, winding and loading rigid pipes before installation.

[001127] In one embodiment of the invention, pipe lashes are wound onto large spools on barges (as illustrated in FIG. 136E) and are not unwound when the barge arrives at the place of work. In one embodiment of the invention, coiled tubing is not unwound on a ship, ship or barge during procedure 6916, and then pipe sections are deployed during procedure 6918. In one embodiment, the “unwinding” ship, ship or barge may be a J- pipe-laying or barges with S-pipe-laying. In FIG. 136E illustrates barges with S-shaped pipe-laying and J-shaped pipe-laying.

[001128] In one embodiment, the S42 pipe barge 6942 receives stored pipe sections from the pipe storage. In one embodiment, during procedure 6906, an S-shaped pipe barge 6942 uses its airborne systems to produce long pipe sections. In one embodiment, on an S-shaped pipe barge 6942, during procedure 6906, automatic welding systems, pipe laying systems, backup clamps, purge and / or other auxiliary equipment are used to produce long pipe sections. In one embodiment of the invention, an S-lay pipe deployment procedure is used for offshore pipelines. In one embodiment of the invention, the procedure for deploying S-shaped pipes is used in shallow water and in intermediate waters. In one embodiment of the invention, the procedure for deploying S-shaped pipes allows the pipe to leave the ship in a horizontal position. In one embodiment of the invention, the procedure for deploying S-shaped pipes provides high levels of productivity. As illustrated in FIG. 136C, barge 6942 with an S-shaped pipe laying is designed and configured to deploy sections of pipes with an S-shaped laying.

[001129] In one embodiment of the invention, the J-pipe barge 6944 receives the stored pipe sections from the pipe storage. In one embodiment, during procedure 6908, the J-pipe barge 6944 uses its airborne systems to produce long pipe sections. In one embodiment of the invention, on a J-pipe barge 6944 during procedure 6908, automatic welding systems, pipe-laying systems, J-clamps and / or other accessories are used to produce long pipe sections. In one embodiment of the invention, a J-lay pipe deployment procedure is used for offshore pipelines. In one embodiment of the invention, the procedure for deploying J-shaped pipes is used at great depths. In one embodiment of the invention, the procedure for deploying J-shaped pipes allows the pipe to leave the laying system in a very close vertical position. This means that the pipeline is installed with a very reduced load on the pipe. As illustrated in FIG. 136D, barge 6944 with a J-shaped pipe-laying is designed and configured to deploy sections of pipes with a J-shaped pipe-laying.

[001130] The control, positioning and communication with the internal welding system, the pipe lash welding system and / or pipe cooler systems when they are located inside the pipe can be performed in various ways, as described herein. In yet another embodiment of the invention, the position of the system inside the pipe can be detected by transmitting a low-frequency electromagnetic signal with a frame antenna located in close proximity to the outer surface of the pipe. This signal is detected by a pair of orthogonal receiving measuring loop antennas mounted on the system in the pipe, in close proximity to the inner surface of the pipe. The phases of the received signals relative to the transmitted signal and the ratio of the amplitudes of the two received signals are used to estimate the relative position of the transmitter and receivers. The control of the system inside the pipe (i.e., an internal welding machine, a device for welding pipe lashes or a cooling system, etc.) along with the transmission of information can also be performed using high-frequency radio communication using broadband signals with a direct sequence between one or more processors ( for example, inside a computer console) outside the pipe and one or more processors installed on the system in the pipe. Details of this deployment can be found in US Pat. No. 6,092,406, incorporated herein by reference in its entirety.

[001135] Testing and field system operations

[001136] In FIG. 137A, a 13700 system is illustrated to facilitate testing of a field system or its operations in accordance with one or more embodiments of the invention. As illustrated in FIG. 137, system 13700 may comprise one or more field systems 13702 (or field systems 13702a-13702n), one or more remote computer systems 13704, and one or more networks 150 through which components of system 13700 can communicate with each other. Field system 13702 may include one or more field devices 13712, one or more control devices 13714, one or more field computer systems 13716, or other components. Remote computer system 13704 may include one or more processors 13730 configured to execute one or more subsystems, such as an object profile subsystem 13732, an operation manager subsystem 13734, an operation protocol subsystem 13736, an operation control subsystem 13738, an operation trigger subsystem 13738, a presentation subsystem 13742 or other components. As described below, in one or more embodiments of the invention, the operations of the respective components of the remote computer system 13704 may be performed by one or more processors of the remote computer system 13704. It should be noted that although one or more operations are described herein as performed by components of the remote computer system 13704 , these operations may, in some embodiments of the invention, be performed by components of a field system 13702 (e.g., field computer system 13716) or other components cients 13700 system.

[001137] In one embodiment, the field system 13702 may be a field system 5000. In one embodiment, when the computer system 5138 is local to the field system 5000, the field computer system 13716 may be a local computer system 5138, and processors of the field computer system 13718 may be processors of the local computer system 5140. If the computer system 5138 is located remotely from the field system 5000, the remote computer system 13704 may be deleted computer system 5138, and the processors of the remote computer system 13730 may be processors of the remote computer system 5140.

[001138] In FIG. 137B illustrates communication lines between a remote computer system 13730, a field computer system 13716 of a field system 13702, and other components of a field system 13702, in accordance with one or more embodiments of the invention. In one embodiment of the invention, the remote computer system 13704 (or its processors 13730) can communicate with one or more other components of the field system 13702 via the field computer system 13716 (and one or more wired or wireless communication links between the field computer system 13716 and the remote computer system 13704). By way of example, processors of the field computer system 13718 may receive verification data, input parameters, operation monitoring data, or other data from one or more other systems of the field system 13702 (or their respective processors 13720), such as a welding system 3001 (e.g., an internal system lashing pipe 3001), a welding system 5004 (e.g., internal welding system 5004), a cooling system 6500 (e.g., an internal cooling system 6500), a purge and inspection system 7001, a welding system 7500 (e.g. an external system welding system 7500) or other systems 13724 of the field system 13702 (e.g., platforms or other pipe alignment systems, other monitoring systems, etc.). Processors 13718 of a field computer system can transmit (via a transmitter) verification data, input parameters, operation monitoring data or other data to a remote computer system 13704 and in response receive a response containing profile data (for example, state profile data before welding, data “on fly ”, status profile data after welding, etc.), instructions for performing operations at the facility, warnings (for example, indicating a defect in the case when there is a defect indicating the beginning or termination of operations etc.) or other data from the remote computer system 13704. In one case, if the response contains profile data, the processors of the field computer system 13718 can use the profile data to generate warnings (for example, indicating a defect in the event that a defect exists indicating the beginning or termination of the operation, etc.), receiving instructions for performing operations on the object, etc. In another use case, if the response contains instructions for performing an operation on an object, the processors of the field computer system 13718 may transmit instructions to the corresponding system of the field system 13702 to instruct the system to perform the operation in accordance with the transmitted instructions.

[001139] In one embodiment of the invention, it may be useful to use one or more wireless communication lines to provide one or more components of a remote computer system 13704, field computer system 13716, welding system 3001, welding system 5004, cooler system 6500, purge and inspection system 7001 or 7500 welding systems that can communicate with each other to reduce the number of communication cables in various systems of the field system 13702 to reduce possible cable entanglement that may delay of operation or damaging other components of these systems. For example, by reducing the number of communication cables in a welding system 3001, a welding system 5004, a purge and inspection system 7001, or a welding system 7500, in some embodiments of the invention, it is possible to reduce possible cable entanglement during rotation of a control device (for example, a control laser, a control chamber, or another control device), welding torch, or other component of these systems.

[001140] In FIG. 137C illustrates communication lines between a remote computer system 13730 and components of a field system 13702 without a field computer system 13716 in accordance with one or more embodiments of the invention. In one embodiment of the invention, the remote computer system 13704 (or its processors 13730) can communicate with one or more other components of the field system 13702 via one or more wired or wireless communication links between different systems of the field system 13702 and the remote computer system 13704 (for example, without the need for a separate field computer system 13716). As an example, processors of a remote computer system 13730 may receive verification data, input parameters, operation monitoring data, or other data from one or more systems of the field system 13702 (or their corresponding electronic modules), such as a welding system 3001 (e.g., an internal system lashing pipe 3001), welding system 5004 (e.g., internal welding system 5004), cooling system 6500 (e.g., internal cooling system 6500), purge and inspection system 7001, welding system 7500 (e.g. external welding YSTEM 7500) system or other system field 13724 13702 (e.g., the inner cooler). In response, the corresponding systems of the field system 13702 receive one or more responses containing profile data (for example, profile data before welding, profile data obtained on the fly, profile data after welding, etc.), instructions for performing operations on the site warnings (for example, indicating a defect in the case when there is a defect indicating the beginning or termination of the operation, etc.), or other data from the remote computer system 13704. In one use case, for example, in the case when one of field systems th system 13702 receives a response containing instructions for performing operations on an object, the system can perform an operation in accordance with the transmitted instructions.

[001141] As another example, one or more electronic modules 5014, 5046, 5064, 5118 or other components of the welding system 5004 may include one or more processors configured to communicate with a field computer system 13716 (or its processors 13718), a remote computer system (or its processors 13730) or other components of the welding system 5004 through one or more wired or wireless communication lines. In one scenario, for example, one or more electronic modules 5014, 5046, 5064, 5118 can receive data from one or more sensors or control devices of the welding system 5004, process sensor data or test data, transmit sensor data or test data to field computer processors systems 13718 or processors of a remote computer system 13730, generate signals for controlling one or more motors or other mechanisms of the welding system 5004 to perform one or more operations, etc.

[001142] As another example, one or more electronic modules 3126, 13722 or other components of the welding system 3001 may include one or more processors configured to communicate with a field computer system 13716 (or its processors 13718), a remote computer system (or its processors 13730) or other components of the welding system 3001 through one or more wired or wireless communication lines. In one scenario, for example, one or more electronic modules 3126, 13722 can receive data from one or more sensors or control devices of the welding system 5004, process sensor data or test data, transmit sensor data or test data to processors of a field computer system 13718 or processors of a remote computer system 13730, generate signals for controlling one or more engines or other mechanisms of the welding system 3001 to perform one or more operations, etc.

[001143] As another example, one or more electronic modules 6528, 13722 or other components of a cooler system 6500 may include one or more processors configured to communicate with a field computer system 13716 (or its processors 13718), a remote computer system (or its processors 13730) or other components of the cooler system 6500 through one or more wired or wireless communication lines. In one scenario, for example, one or more electronic modules 6528, 13722 can receive data from one or more sensors or control devices of the cooler system 6500, process sensor data or test data, transmit sensor data or test data to processors in a field computer system 13718 or processors of a remote computer system 13730, generate signals for controlling one or more engines or other mechanisms of the cooler system 6500 to perform one or more operations, etc.

[001144] As another example, one or more electronic modules 7032, 7036, 7040, 7064 or other components of the purge and check system 7001 may comprise one or more processors configured to communicate with a field computer system 13716 (or its processors 13718), a remote computer system (or its processors 13730) or other components of a purge and test system 7001 via one or more wired or wireless communication lines. In one scenario, for example, one or more electronic modules 7032, 7036, 7040, 7064 can receive data from one or more sensors or control devices of a purge and test system 7001, process sensor data or test data, transmit sensor data or test data to processors field computer system 13718 or to the processors of the remote computer system 13730, generate signals to control one or more engines or other mechanisms of the purge and check system to perform one or more operations, etc.

[001145] As another example, one or more electronic modules 3126, 13722 or other components of the welding system 3001 may comprise one or more processors configured to communicate with a field computer system 13716 (or its processors 13718), a remote computer system (or its processors 13730) or other components of the welding system 3001 through one or more wired or wireless communication lines. In one scenario, for example, one or more electronic modules 3126, 13722 can receive data from one or more sensors or control devices of the welding system 5004, process sensor data or test data, transmit sensor data or test data to processors of a field computer system 13718 or processors of a remote computer system 13730, generate signals for controlling one or more engines or other mechanisms of the welding system 3001 to perform one or more operations, etc.

[001146] In one embodiment of the invention, a field system (eg, field system 5000, field system 13702, etc.) may operate with one or more remote computer systems (eg, computer system 5138, which is located remotely from field system 5000, remote computer 13704, etc.) to facilitate field testing or physical operations based on them. A field system may comprise one or more components that may be associated with being able to communicate with each other and / or with one or more components of remote computer systems. In one embodiment of the invention, one or more field devices (eg, field devices 13712) of a field system may be ordered to perform one or more operations based on the results of a scan of one or more objects. As an example, a monitoring device (e.g., monitoring device 13714) of a field system can verify an object. One or more processors of the field system (for example, processors 13718 of the field computer system 13716) may receive verification data associated with the verification of the object from the monitoring device. Based on the verification data, the processors can order the field device of the field system to perform an operation that physically affects the object. The control device may include a control laser, a control camera, an X-ray control device, a gamma radiation control device, an ultrasonic control device, a magnetic particle control device, an eddy current control device, a temperature monitor or other control device. The test data may include laser control data, control camera data, x-ray control data, gamma radiation control data, ultrasonic control data, magnetic particle control data, eddy current control data, temperature control data or other test data.

[001147] In one embodiment of the invention, field system processors (eg, processors 13718 of field computer system 13716) may process the verification data to generate data associated with performing an operation that physically affects the object and instruct the field device to perform the operation based on the data, related to the operation. In one embodiment of the invention, field system processors may transmit (via a transmitter) verification data to a remote computer system. In response to the transmission of verification data, processors can receive data from a remote computer system related to an operation that physically affects the object. As an example, operation-related data may be generated in a remote computer system based on verification data. After receiving data associated with the operation, the processors may instruct the field device to perform the operation based on the data associated with the operation. Processors can instruct the field device to perform an operation by transferring the data associated with the operation to the field device (for example, in a format that the field device can interpret and use to perform the operation), use the data associated with the operation to control the field device to perform the operation, monitor and provide on-the-fly updates for the operation (for example, by monitoring an object during the operation) or other methods.

[001148] In one embodiment of the invention, the verification data may be processed to automatically determine whether an object has one or more defects, whether the object is ready for the next step of operations, or other information. As an example, in the case where one or more defects are detected based on the verification data, the generated data associated with the operation may relate to performing an operation to eliminate the detected defects. As another example, in the case where it is determined that the object is ready for the next step of operations, the generated data associated with the operation may relate to the execution of the operation associated with the next step of operations.

[001149] A field device (eg, field device 13712) may include a welding device, a coating device, an alignment device, a heating device, a cooling device, a protective device, a control device, or other device. Operation related data may include welding related instructions, coating instructions, change related instructions, leveling instructions, or other instructions or data. Instructions related to welding may include instructions related to welding in the area of the contact surface between the first object and the second object (for example, the area of the contact surface between pipes or other objects), instructions related to the wire feed speed, wire consumption, width oscillations, vibration mode, vibration amplitude, welding time, gas consumption, welding arc power levels, welding current, welding voltage, welding resistance, welding torch travel speed and, a welded tip position of the welding torch along the tube axis, the angular positioning of the weld torch tip with respect to its plane of rotation, the distance from the welding torch tip welded to the inner surface of welded pipes, etc. for welding, or other welding related instructions. Coating instructions may include instructions for coating an object (eg, coating a pipe or other object), instructions related to preheating temperature, coating thickness, or other instructions related to coating. Instructions associated with the changes may include instructions related to expanding at least part of the object, instructions related to reducing at least part of the object, instructions related to resizing at least part of the object (for example, changing the radial dimensions, proportional resizing, etc.), changing the shape of at least part of the object, or other instructions associated with the changes. Instructions related to alignment may include instructions related to aligning at least part of an object with at least part of another object, or other instructions related to alignment.

[001150] In one embodiment of the invention, based on the verification data associated with checking the contact surface area between the first object and the second object, one or more processors of the field system (for example, processors 13718 of the field computer system 13716) may receive data associated with the operation welding in the area of the contact surface. As an example, processors can transmit (via a transmitter) verification data to a remote computer system (e.g., remote computer system 13704), and in response, processors can receive welding instructions in the contact area from a remote computer system. Processors can direct a field device to perform welding in the area of the contact surface based on welding instructions.

[001151] In one use case, when it is determined from the inspection data that the first layer of the welding passage has a defect (but can nevertheless be changed due to the second welding passage), welding instructions may include instructions for making the second welding pass so that the second welding pass eliminates a layer defect of the first welding pass. As an example, in the case where it is determined that the layer of the first welding passage is not thick enough, welding instructions may include instructions for allocating more time to welding or using a welding wire (in the case when it was determined that the layer the first welding pass is thick enough) for the second welding pass. Thus, the obtained layer of the second welding passage can be thicker (than it would otherwise be) to compensate for the insufficiently thick layer of the first welding passage. As another example, in the case where it is determined that the layer of the first welding pass is too thick, welding instructions may include instructions for setting aside less time for welding or using a welding wire (if it was determined that the layer of the first the welding pass was sufficiently thick) for the second welding pass. Thus, the obtained layer of the second welding passage can be thinner (than it would otherwise be) in order to compensate for the additional layer thickness of the first welding passage.

[001152] In another use case, when a defect is detected in the layer of the first welding passage, welding instructions do not need to include instructions for repairing or repairing the detected defect. As an example, a repair may not be recommended in the event of a defect based on the size of the defect that does not meet the predefined threshold for the size of the defect (for example, the size of the defect to be repaired is too minimal to recommend repair). A predefined threshold for the size of the defect may, for example, correspond to the size of the defect, which will not have a significant negative effect on the quality of the weld. Thus, in this case of use, if the defect size in the layer of the first welding passage is less than the predetermined threshold for the size of the defect, welding instructions may simply include instructions for the layer of the next welding passage, as if the defect were not detected .

[001153] In one embodiment, based on the verification data associated with the verification of the object, one or more processors of the field system (eg, processors 13718 of the field computer system 13716) may receive data related to coverage of the object. As an example, processors can transmit (via a transmitter) verification data to a remote computer system (e.g., remote computer system 13704), and in response, processors can receive instructions from the remote computer system related to covering the object. Processors may direct a field device to apply one or more coating layers to an object based on coating instructions. In one case, when it is determined on the basis of the verification data that the welding of the object is completed and that the completed weld is within the specification, the remote computer system can transmit instructions to the processors of the field system instructing to start coating the object.

[001154] In one embodiment, based on the verification data associated with the verification of the object, one or more processors of the field system (eg, processors 13718 of the field computer system 13716) may receive data related to a change in the size, shape, or other aspect of the object. As an example, processors can transmit (via a transmitter) verification data to a remote computer system (e.g., remote computer system 13704), and in response, processors can receive instructions from the remote computer system related to changing the object. Processors may require the field device to increase at least part of the object, reduce at least part of the object, radially resize at least part of the object, change the shape of at least part of the object (for example, processing a new chamfer at the end of the pipe or making changes to the shape) or making other changes to the object based on the instructions associated with the changes.

[001155] In one embodiment, based on the verification data associated with the verification of the object, one or more processors of the field system (eg, processors 13718 of the field computer system 13716) may receive data related to alignment of the object. As an example, processors can transmit (via a transmitter) verification data to a remote computer system (e.g., remote computer system 13704), and in response, processors can receive instructions from the remote computer system related to aligning the object. Processors can direct a field device to align at least a portion of an object with at least a portion of another object based on alignment instructions. In one use case, for example, when the objects are pipes, and analysis of the verification data of the remote computer system indicates an alignment error, alignment instructions received from the remote computer system may include instructions for changing the position of at least one of pipes, for which an alignment error was recorded (for example, an angular error that led to the formation of a gap between the pipes, a positioning error that led to difficulties with a stepped transition, etc.).

[001156] In one embodiment of the invention, one or more operations may be performed on one or more objects based on the results of inspections of several objects. Thus, for example, verification data obtained as a result of checking several objects can be used to analyze the objects as a whole. In some scenarios, such an analysis may otherwise be incomplete if it comes down to considering the verification data of only one object. By way of example, although each of the individual pipeline pipes may be within the specification, the pipeline or its section (containing many individual pipes) as a whole may go beyond the specification. As another example, although individual pipeline pipes may be ready for the next stage of operations, the pipeline or section of the pipeline as a whole may not be ready for the next stage of operations. Using the verification data obtained from the verification of each of the pipes in the pipeline or section of the pipeline, a more complete analysis of the pipe or section of the pipeline as a whole can be performed.

[001157] In one embodiment, one or more field system processors (eg, processors 13718 of a field computer system 13716) may receive (via a receiver) first verification data associated with a verification of a first object and second verification data associated with a verification of a second object . Based on the first test data and the second test data, the processors can order the field device of the field system to perform an operation that physically affects one or more objects. Both the first test data and the second test data may include at least one of the laser test data, camera test data, x-ray test data, gamma radiation control data, ultrasonic control data, magnetic particle control data, eddy current control data, control data temperature or other verification data. Verification of the first object and verification of the second object can be performed by the same control device or by different control devices.

[001158] In one embodiment, the field system processors (eg, processors 13718 of the field computer system 13716) may process the first verification data and the second verification data to generate data related to performing an operation that physically affects the object and instruct the field device to perform operations based on data associated with the operation. In one embodiment of the invention, the field system processors may transmit the first verification data and the second verification data to a remote computer system (eg, remote computer system 13704). In response to the transmission of the first verification data and the second verification data, the processors can receive data from a remote computer system related to the execution of an operation that physically affects the object. As an example, operation-related data may be generated in a remote computer system based on the first verification data and the second verification data. After receiving data associated with the operation, the field system processors may instruct the field device to perform the operation based on the data associated with the operation.

[001159] In one embodiment of the invention, data associated with the operation (on which the execution of the operation on the object is based), as an additional or alternative option, can be based on one or more input parameters of one or more operations performed on one or more objects (e.g., object, other object, etc.). As an example, a field device in a field system can perform operations before checking an object. Input parameters of previously performed operations, verification data related to object verification, or other data can be transferred to a remote computer system. After receiving the transmitted data, the remote computer system may generate operation-related data based on input parameters, verification data, or other data. In the case when, for example, a defect is detected on the basis of the control data, the input parameters can be analyzed in connection with the defect found to determine the cause of the defect (for example, the actual output results do not correspond to the theoretical output results of the input parameters), and the data associated with the operation be generated so that the data associated with the operation can be used to perform an operation that is designed to repair or eliminate a detected defect or ranks defect.

[001160] In one use case, when it is determined that the layer of the first welded passage obtained as a result of the welding operation is not thick enough (based on the verification data associated with the verification of the layer of the first welded passage), the input parameters for the welding operation may be taken into account to determine the reasons for the insufficient thickness of the layer of the first welding passage. For example, in the case where it is determined that the reason for the insufficient thickness is insufficient time allocated for welding or the insufficient number of welding wires, welding instructions for the second welding pass may be generated containing input parameters calibrated to compensate for the insufficient thickness of the first layer welding pass or an established cause of such a failure (for example, more welding time, more wire used, etc. )

[001161] Processing data received from the field system

[001162] In one embodiment, a computer system (eg, computer system 5138, remote computer system 13704, field computer system 13716, etc.) may operate with one or more field systems (eg, field system 5000, field system 13702 ) to facilitate field testing or physical operations based on them. A computer system may comprise one or more processors, or other components that may be associated with being able to communicate with each other and / or with one or more components of one or more field systems. The computer system may be a local computer system with respect to at least one of the field systems or a remote computer system with respect to at least one of the field systems. In one embodiment of the invention, the processors of the computer system may receive verification data associated with the verification of the object from the field system. Processors can process validation data to generate data related to an operation that physically affects the object. Processors can transfer operation-related data to the field system to direct the field system to perform an operation that will physically affect the object. As an example, a field system may perform an operation based on data associated with the operation. As described herein, operation related data may include welding related instructions, coating related instructions, modification related instructions, leveling related instructions, or other instructions or data.

[001163] In one embodiment of the invention, the processors of a computer system can receive (via a receiver) verification data associated with the verification of several objects from one or more field systems and generate data related to the execution of an operation that physically affects an object of at least one of the field systems. Processors can transfer operation-related data to the field system to direct the field system to perform an operation that physically affects the object. Inspection data associated with inspections of each object may include at least one of laser inspection data, camera inspection data, X-ray inspection data, gamma radiation inspection data, ultrasonic inspection data, magnetic particle inspection data, eddy current inspection data, temperature control data or other verification data. Checks of several objects can be performed by the same control device or by different control devices.

[001164] In one embodiment of the invention, data associated with the operation (on which the execution of the operation on the object is based), as an additional or alternative option, may be based on one or more input parameters of one or more operations performed on the object. As an example, a field device (e.g., field device 13712) of a field system may perform operations before checking an object. Processors of a computer system can receive input parameters from previously performed operations, verification data associated with object verification, or other data from a field system or other sources. Computer system processors can generate operation-related data based on the received data. For example, if a defect is detected on the basis of the verification data, the input parameters can be analyzed in connection with the detected defect to determine the cause of the defect (for example, the actual output does not correspond to the theoretical output of the input parameters) and the data related to the operation can be generated so that the associated with the operation, the data could be used to perform the operation, which is intended to repair or eliminate the detected defect or cause of the defect.

[001165] In one embodiment of the invention, data associated with the operation (based on which the operation is performed on the object), as an additional or alternative option, is based on observations of one or more operations performed on one or more other objects. In one embodiment of the invention, computer system processors may monitor one or more operations at one or more objects. As an example, processors can monitor operations through one or more control devices, such as one or any combination of a control laser, a control camera, an X-ray control device, a gamma radiation control device, an ultrasonic control device, a magnetic particle control device, a vortex control device currents, temperature monitor or other control device. During such monitoring, processors can obtain data related to observations of operations, such as observations of one or more field devices during operations, observations of objects during operations, monitoring of environmental conditions during operations, or other observations. Processors can compare observations to determine the circumstances that are likely to be the cause of the defects, and can generate transaction-related data for subsequent operations to avoid or reduce such defects. In one embodiment of the invention, the processors of a computer system can compare one or more sets of observations of an operation performed on one or more objects where a defect is detected (after performing the operation) with one or more other sets of observations of the same operation performed on one or more other objects without a defect, to determine the circumstances that probably caused the defect (as described in more detail elsewhere in this document). In one embodiment of the invention, the definition of such circumstances can be saved and used (for example, in combination with the definition of such circumstances arising in other field systems) to (i) generate and select one or more protocols of operations for subsequent operations (as described in this document) to prevent or reduce defects, (ii) create conditions for detecting defects in the early stages of the process (for example, as described in this document by actively monitoring the operation s, verification "on the fly" during an operation, etc.) or (iii) provide other benefits to create the best products for present and future customers.

[001166] As an example, analysis of verification data for a plurality of welds and observational data for the operation of performing these welds may reveal that the absence of deposition defects is significantly more likely when the welding voltage drops more than 0.5 V below the input parameter welding voltage, while the torch performs welding between the positions on the pipe at “2 hours” and “4 hours”. Conversely, the welding voltage may drop 1.2 V below the input parameter of the welding voltage at other locations on the pipe without causing a defect in the form of a deposition defect. Based on these observations, computer system processors can generate and send new input welding parameters that require welding devices to increase the welding voltage by 0.7 V when the torch is between positions at “2 hours” and “4 hours”. As another example, if the analysis shows that the case of a drop in welding voltage leads to a deficiency in the form of deposition defects, while the torch performs welding on a descent (but not during welding on a rise), the generated new input welding parameters can give an instruction for welding devices to increase the welding voltage only when the torch performs welding to the descent. As another example, in the case where the analysis shows that the case of a drop in the welding voltage is the reason for the absence of welding defects for the external welds (but not for the internal welds), the generated new input welding parameters can instruct external welding devices to increase the welding voltage .

[001167] In one embodiment of the invention, the processors of the computer system can obtain control data associated with inspections of one or more objects, and compare the verification data with a predefined quality profile for these objects. Based on the comparison, the processors can determine whether the object has one or more defects, whether the object is ready for the next stage of operations, or provide other information. As an example, in the case where one or more defects are detected based on the verification data, the operation-related data that is generated may relate to performing an operation to eliminate the detected defects. As another example, when it is determined that the object is ready for the next step of operations, the data associated with the operation that is generated may relate to the execution of the operation associated with the next step of operations.

[001168] As an example, a predefined quality profile may contain one or more size criteria, shape criteria, consistency criteria, alignment criteria, temperature criteria, color criteria, or other criteria. In one embodiment of the invention, the predetermined quality profile for the pipeline pipe may contain one or more acceptable ranges for the inner diameter of the pipe, the outer diameter of the pipe, the thickness of the pipe, the size of the contact surface area between one pipe and another pipe to which the pipe is welded or should be welded , the height of the weld inside the pipe, the height of the weld on the outside of the pipe, the temperature of the metal of the weld or pipe (for example, during a welding operation), the color of the weld metal the weld or pipe during the welding operation (which, for example, may indicate the temperature of the metal of the weld or pipe) or other criteria. A predefined quality profile can correspond to a certain quality level, such as a “gold” quality standard (for example, a high level of quality), a minimum required level of quality, etc.

[001169] In one embodiment, computer system processors may provide verification data associated with inspections of one or more objects, one or more analytical results of the analysis of verification data, or other data for presentation to a user (eg, operator, inspector, manager, or other user) . In one embodiment of the invention, the processors may receive user user input indicating a defect associated with at least one of the objects. As an example, the user can indicate where the defect is detected on the object and what kind of defect it is. Based on this defect, processors can generate operation-related data that can be used to instruct the field system to perform an operation to repair or repair a defect associated with an object.

[001170] In one embodiment of the invention, one or more operation triggers may be provided to eliminate circumstances that lead to one or more defects (for example, in an object, group of objects, project, etc.). As an example, despite using the same input parameters for a specific operation, field devices using these input parameters to perform the operation can perform the operation in different ways, which can lead to the fact that the object (controlled by one field device) will be have a defect, and another object (controlled by another field device) may not have defects. These differences in results can be caused by one or more actual input parameters for field devices that differ from the expected input parameters, one or more actual output parameters for field devices that differ from the expected output parameters, one or more deviations in the objects on which the field devices operate under one or more actual operating conditions that differ from acceptable operating conditions (e.g. environmental conditions, misalignment or improper positioning object, etc.) or other circumstances.

[001171] In one embodiment, computer system processors can monitor one or more operations at one or more objects. During such monitoring, processors can obtain data related to observing operations, such as observing one or more field devices during operations, observing objects during operations, observing environmental conditions during operations, or other observations. Processors can compare observations with each other to generate one or more operation triggers. After the application of such triggers, one or more field systems may require one or more operations to be performed in response to one or more subsequent observations satisfying the respective triggers. Triggers can include one or more triggers that trigger operations to prevent or reduce defects, or other triggers.

[001172] In one embodiment of the invention, based on data related to the observation of operations, computer system processors can compare the first set of observations of the operation performed on the object where the defect is detected (after the operation), with one or more other sets of observations for the same operation performed on one or more other objects without a defect. After comparison, processors can determine one or more differences between the first set of observations and other sets of observations. Based on the differences, processors can generate one or more triggers associated with one or more operations (for example, defect prevention operations or other operations). As an example, in the case where there are general differences between the first set of observations and each of the other sets of observations, it is likely that the observed circumstances corresponding to the general differences caused the defect. Thus, in the case when these circumstances are observed during the subsequent operation, one or more operations can be performed to eliminate these circumstances in order to prevent the occurrence of a defect (for example, by terminating the subsequent operation until the circumstances no longer occur, by changing input parameters for the subsequent operation in order to mitigate circumstances, by generating a warning indicating circumstances, etc.).

[001173] In one embodiment of the invention, based on data related to the observations of operations, computer system processors can compare a second set of observations of the same operation performed on another object where a defect is detected (after the operation is completed) with other observation sets (for the same operation performed on other objects without a defect). After comparison, processors can determine one or more differences between the second set of observations and other sets of observations. As an example, processors can then compare (i) the general differences between the first set of observations and each of the other sets of observations with (ii) the general differences between the second set of observations and each of the other sets of observations to determine the differences common to the first and second sets of observations ( for example, similarities that have both the first and second set of observations and which are common differences compared to other sets of observations of other objects without a defect). Based on differences common to both the first and second set, processors can generate one or more triggers associated with one or more operations (for example, defect prevention operations or another operation).

[001174] In one embodiment of the invention, by comparing one or more sets of observations of the welding operation for the root passage (for one or more areas of the contact surface between the pipes), computer system processors can determine the general differences that at least one set of observations has the welding operation (which led to the appearance of a defect in its root passage) as compared with other sets of observations of the welding operation, during which the root was performed without defect. By way of example, in the case where general differences include a certain deviation between one or more measured input parameters and input parameters used for a welding operation, processors may generate one or more triggers that trigger one or more deviation correction operations when such a deviation is detected . For example, subsequent welding operations for the root passage can be controlled, and if a deviation occurs from the input parameters used by the welding device to perform the welding of the root passage, the generated triggers can order the execution of related operations to eliminate the deviation (for example, changing the input parameters to ensure so that the actual input parameters for the welding operation are in the expected ranges of input parameters associated with unchanged input parameters ramie, generating a warning, which is provided to the operator or to another person or system, the termination of the welding operation, etc.). In other use cases, one or more similar types of triggers may be generated to eliminate circumstances during the coating operation, the pre-heating operation, the cooling operation, the alignment operation, the shielding operation, the verification operation, or other operation, respectively.

[001175] In another use case, when monitoring a subsequent operation at an object, a circumstance corresponding to observations common to defective objects may be detected. In response, an operation trigger for this circumstance may result in an operation associated with an operation trigger that will be performed on the object. For example, computer system processors may change one or more input parameters for a subsequent operation or another operation that must be performed after a subsequent operation. Processors can, for example, change the input parameters for a subsequent operation during a subsequent operation, change the input parameters for another next operation to another subsequent operation, or perform other modification operations associated with the trigger of the operation. The changed input parameters may include one or more welding parameters, coating parameters, alignment parameters, change parameters, or other parameters. As another example, processors can stop a subsequent operation (for example, stop a subsequent operation until further notice), generate a warning during a subsequent operation, indicating circumstances (for example, generate and send a warning to the field system that performs the subsequent operation, provide a warning to the manager, field operator or other personnel, etc.) or perform other operations related to the operation trigger. Thus, for example, the above operation triggers and / or active control can help detect defects in the early stages of the process and prevent or reduce defects to ensure more efficient and productive operations and provide better products to current and future customers.

[001176] Protocols of operations and operations based thereon

[001177] In one embodiment, one or more protocols of operations for performing one or more operations may be generated based on checks of one or more objects. As an example, processors of a computer system (e.g., computer system 5138, remote computer system 13704, field computer system 13716, etc.) can receive data from a field system (e.g., field system 5000, field system 13702, etc.) checks related to checking the object (for example, checking before performing one or more operations that physically affect the object, checking during the execution of operations, checking after performing operations, etc.). Processors can generate an operation protocol (associated with at least one operational type of operation) based on verification data and one or more input parameters used to perform the operations. The operation protocol may, for example, include a welding protocol, a coating protocol, an alignment protocol, a change protocol, or another protocol. One or more parameters of the operation protocol may comprise one or more welding parameters, coating parameters, alignment parameters, change parameters, or other parameters.

[001178] In one embodiment, computer system processors may select an operation protocol to perform a subsequent operation similar to at least one of the operations (which physically affect an object). Processors may generate, based on at least one input parameter of the operation protocol, data associated with the subsequent operation. Processors can transfer operation-related data to the field system to direct the field system to perform a subsequent operation. As an example, a field system may perform a subsequent operation based on data associated with the operation.

[001179] In one embodiment, based on the verification data, the processors of the computer system can detect a defect associated with the object. In response to defect detection, processors can generate an operation protocol so that the operation protocol contains a set of input parameters having at least one input parameter different from the set of input parameters used to perform the operations. As an example, a predetermined operation protocol can be used to perform an operation on an object. In the event that a defect is detected on the object based on an inspection of the object, the predetermined operation protocol can be changed to avoid similar defects when the predetermined operation protocol is used for one or more subsequent operations, similar to the operation that probably led to object defect. The changed operation protocol can be saved as a new predefined operation protocol, which will replace the previous version of the predefined operation protocol, etc.

[001180] In one embodiment of the invention, a predetermined welding operation protocol may be used to perform a welding operation to weld two pipes together, wherein a predetermined welding operation protocol may include input parameters related to wire feed speed, wire consumption, width oscillations, oscillation amplitude, welding time, gas flow rate, welding arc power levels, welding current, welding voltage, welding resistance, speed displacements of the welding torch, the tip position of the welding torch along the tube axis, the angular positioning of the tip of the welding torch relative to its plane of rotation, the distance from the welding torch tip welded to the inner surfaces of welded pipe or other parameters. In the case where, for example, it is determined that a layer of a welding passage of insufficient thickness is formed during the welding operation, the predetermined welding operation protocol may be changed to provide more welding time, more wire used (for example, increased wire feed speed) or other changes to the input parameters of a predefined welding operation protocol. Thus, when the modified operation protocol is subsequently used to perform a similar operation on two similar pipes, changing the input parameters can prevent the problem of insufficient thickness.

[001181] In one embodiment of the invention, based on the verification data, the computer system processors can determine whether or not the quality of one or more aspects of the object that results from operations (which physically affect the object) matches or exceeds the specified quality standard according to a predefined quality profile. As an example, processors can generate an operation protocol so that the working protocol contains one or more input parameters (used to perform operations) that correspond to the quality of the aspects of the object that meet or exceed the quality standard indicated by a predefined quality profile. A predefined quality profile can correspond to a certain quality level, for example, a “gold” quality standard (for example, a high level of quality), a minimum required level of quality, etc. In the case where the quality of the aspects of the object meets or exceeds the quality standard specified in the predefined quality profile, the input parameters (used to perform operations that lead to such results) can be used to generate an operation protocol (for example, so that the operation protocol contains some or all of the input parameters). Thus, for example, an operation protocol can be used to perform one or more subsequent operations similar to an operation that yields results such that subsequent operations provide similar quality.

[001182] As another example, if the quality of aspects of an object does not meet a quality standard (indicated by a predefined quality profile), processors can generate an operation protocol so that the operation protocol does not contain one or more input parameters (used to perform operations that led to the checked state of the object). In one use case, if a predetermined protocol of an operation (containing input parameters used to perform operations) was selected to perform at least one of the operations, and the quality of aspects of the obtained object did not satisfy the minimum required level of quality, then one or more input parameters a certain protocol of operations can be changed to avoid subsequent unsatisfactory results when a predefined protocol of operations will be spolzovat for the subsequent operations.

[001183] In one embodiment of the invention, computer system processors can obtain verification data associated with inspections of one or more objects, and compare the verification data with a predefined quality profile for objects to determine whether the quality of one or more aspects of the objects matches or exceeds quality standard specified in a predefined quality profile. As an example, based on a comparison, processors can determine whether an object has one or more defects, whether the object is ready for the next stage of operations, or generate other information. As another example, in response to quality aspects of the facility that exceed the quality standard specified by the predefined quality profile, processors can generate a new quality profile based on the verification data, while the new quality profile will indicate a new quality standard that is based on the verification data . A new quality profile, for example, may be stored in a database for use in analyzing one or more aspects arising from one or more subsequent operations.

[001184] In one embodiment of the invention, computer system processors may provide verification data associated with inspections of one or more objects, one or more analytical results of analysis of verification data, or other data for presentation to a user (eg, operator, inspector, manager, or other user) . In one embodiment of the invention, the processors may receive user input from a user indicating the quality level of one or more aspects of an object as a result of one or more operations (e.g., low quality level, high quality level, etc.). In response to user input, processors can generate a new quality profile associated with the specified quality level, with the new quality profile indicating a new quality standard based on verification data. A new quality profile may, for example, be stored in a database for use in analyzing one or more aspects arising from one or more subsequent operations.

[001185] In one embodiment, computer system processors can generate one or more operation protocols based on data associated with input parameters used to perform one or more operations, data related to monitoring operations, verification data related to object verification on which operations are performed (for example, before, during or after the operation), or other data. As an example, processors can analyze the verification data to determine if any object has defects. Processors can then compare one or more sets of observations of an operation performed on one or more objects where a defect is detected (after performing an operation) with one or more other sets of observations of the same operation performed on one or more other objects without a defect to identify circumstances that are likely to lead to a defect (as described in more detail elsewhere in this document). Based on the comparison, processors can generate operation protocols so that the operation protocols exclude or otherwise prevent circumstances (which probably led to a defect) when the operation protocols are used for one or more subsequent operations (for example, subsequent operations that are same or similar to the performed and observed operation).

[001186] As another example, if it is observed that the input parameters used to perform the operation on one or more objects are different from the input parameters used to perform the operation on one or more other objects, then the processors can compare these observations with each other another to determine if differences in input parameters can cause a defect. For example, observations can be compared to determine the general differences between the input parameters used to perform operations on an object with a defect received and the input parameters used to perform operations on objects without a defect. Based on common differences, processors can generate operation protocols so that operation protocols do not include input parameters that are likely to cause a defect. The generated operation protocols can be stored so that the operation protocols can be used in one or more subsequent operations (for example, subsequent operations that are the same or similar to the performed and observed operations). For example, in one use of the welding protocols, analysis of the test data for several welds and the observation data for these welds may reveal that the absence of deposition defects is much more likely when the welding voltage drops more than 0.5 V below the input parameter of the weld voltage, while the torch performs welding between the positions on the pipe at “2 hours” and “4 hours”. Conversely, the welding voltage may drop 1.2 V below the input parameter of the welding voltage at other locations on the pipe without causing a defect in the form of a deposition defect. Based on these observations, computer system processors can generate welding protocols containing new input welding parameters that indicate the need to increase the welding voltage by 0.7 V when the torch is between positions at “2 hours” and “4 hours”.

[001204] In one embodiment of the invention, a defect associated with the object can be detected based on data obtained from verification related to the analysis of the object (14002). As an example, the analysis can be performed after a process operation that was performed at the facility using a first set of input parameters (e.g., welding parameters, coating parameters, or other input parameters). The data obtained as a result of the verification can be provided by the field system, where the data obtained as a result of the verification may contain data obtained as a result of the laser verification, data obtained as a result of the camera inspection, data obtained as the result of the X-ray verification, data obtained as a result of verification by gamma radiation, data obtained as a result of verification by ultrasonic testing, data obtained as a result of verification by the magnetic particle method, data obtained as a result of testing RCTs eddy current data obtained as a result of temperature check methods or other data obtained from the inspection.

[001242] In one embodiment of the invention, the user can configure work locally or in the cloud. In a cloud example, a user can use and / or inherit information related to work from a cloud that must be retrieved or placed on a device and / or user machine (for example, a computer 14416 connected to a welding machine 14412).

[001251] uLog can also automatically report on machine status errors, automatically mark the job location in job records, and synchronously receive records of changes in work-related parameters from all users for a given project. In addition, uLog can also generate for customers a consolidated report related to the project from one point.

[001252] In FIG. 155 shows an example of GUI for the “Real-time Log” screen of an application for cloud universal data logging (uLog), showing voltages versus time at one welding station in accordance with an embodiment of the present invention. In one embodiment of the invention, uLog performs a centralized collection of data received from all machines that manipulate the pipes during welding, machines associated with the coating, as well as all types of data related to such machines and activities. A current summary of real-time welding, coating and control activities can be created. The table shows various parameters, including: event number, time stamp, zone identification, inclination of the welding device or welding system in degrees, speed of movement of the welding device, voltage applied or voltage supplied to the welding wire, current supplied (A) or current fed to the welding wire, wire feed speed or welding wire speed, etc. For example, various parameters, including the feed speed of the welding wire (i.e., the speed of the welding wire) and the speed of the welding device (speed of movement), as well as other parameters can be presented in the form of a table and / or graphs. In addition, the voltage applied to the welding wire can also be displayed in a table and / or in the form of a graph versus time.

[001253] Optionally, uLog may support electronic signatures to PQR / WPS documents. Optionally, uLog can control the version of system parameters and roll back. In one embodiment, uLog also has functionality for deploying daily job statistics from cloud and / or mobile devices. For a non-limiting example, uLog can perform data management and can provide user reports on the number of welds completed over a specific period of time (for example, per hour, one day, a week, etc.) and can report the amount of material consumed (e.g. welding material) used for a certain period of time (for example, per hour, for one day ...) or another period of time. ULog can also receive job and error reports.

[001254] In one embodiment of the invention, uLog may send an email and / or SMS (text message) or other notification to the appropriate authorities. uLog can also be used for financial functions, accounting auditing, time tracking and other management tasks. For example, uLog can bill customers on time. In one embodiment of the invention, an invoice can be created based on the number of welds or based on the consumables that were used and / or the amount of waste. uLog provides a quantification system and supports efficient billing and accounting for pipeline welding projects.

[001255] uLog can also be used to automatically replenish materials and / or equipment and / or other resources or inventory during a project. The numerous and varied uLog functions described in this document can reduce the number of violations during the execution of the task, downtime, losses and other negative manifestations during construction.

[001256] In FIG. Figure 156 shows an example of GUI for the Get Log screen of a cloud-based application for universal data logging (uLog), showing the parameters of the welding data, including the type of welding event, time, zone, seam movement speed (welding system moving speed) wire feed speed (welding speed wire) in accordance with an embodiment of the present invention. In FIG. 156 shows the various parameters that are reported in the table, including: weld identification or type number, event number, time stamp, zone identification, tilt of the welding device or welding system in degrees, movement speed of the welding device, voltage applied or voltage applied to the welding wire, supplied current (A) or current supplied to the welding wire and wire feed speed (welding wire speed). In one embodiment of the invention, uLog can automatically mark the job location in job records. In other examples, a time stamp can be entered in the data logs and time zones can be displayed, as shown in the table depicted in FIG. 156. Timestamps can be synchronized with GPS and / or based on data available and / or entered into uLog, so that the logs display the time zone in which they were recorded.

[001257] In FIG. Figure 157 shows an example of GUI for the summary report screen of an application for cloud universal data logging (uLog) that displays various welding parameters, including welding time, welding station identification number, arc voltage, etc. according to an embodiment of the present invention. In one embodiment of the invention, uLog can create and / or generate PQR and / or WPS and / or summary reports and / or daily reports, all executed on a mobile platform and on the cloud. PQR, WPS, summary and daily reports can be created manually or generated automatically. uLog can generate one, several or all of these types of reports on a schedule, for this case or at the same time. uLog provides the advantage of processing shared and consistent data. Identity data collected can be used to create reports at the same or different locations and / or output devices.

[001258] Reporting rules may be set on uLog, which may be customizable. In one embodiment of the invention, critical data for a given project can be synchronized in the cloud. uLog provides for the creation of a qualification editor of project links, which should be sent to the user and / or client of the user and / or other recipient at the end of the qualification process with electronic signatures for approval. uLog reduces time and costs when creating these reports and approved documents.

[001259] In FIG. 158 shows an example of a GUI for the Save Data in Log screen of a universal universal data logging (uLog) application displaying various icons according to an embodiment of the present invention. uLog provides unlimited storage services. The pipeline construction industry is widespread throughout the world, and its projects can be geographically dispersed. In addition, the construction of the pipeline can occur in adverse environmental conditions and in harsh climates. uLog allows you to store and protect data in any place where the user and / or equipment can be located. Data may also be synchronized or otherwise processed. For example, data received from a job, a logbook, a welding station, a welding parameter, reports, and job locations can be stored in the cloud. In one embodiment of the invention, location data may be stored in addition to technical data and / or control data.

[001260] In FIG. 159 shows an example GUI for the Analytics screen of an application for cloud universal data logging (uLog), showing two icons for selecting the type of analysis to be performed (eg, trend, moving average) in accordance with an embodiment of the present invention. In one embodiment of the invention, uLog analytics can process and provide data trends, moving averages, and / or any type of data processing that the user requires. In one embodiment of the invention, uLog may have cloud logging systems, reporting systems, and analytics. For example, analytics can be performed based on the data collected to provide feedback to the control system in order to improve the quality and prediction of defects in welds and / or construction equipment, activities and manufacturing operations. In one embodiment of the invention, data may be collected using the cloud and / or one or more mobile devices. In one embodiment of the invention, uLog supports the synchronized receipt of notes on the change of work-related parameters from all users on a given project. In another embodiment of the invention, uLog can monitor, analyze and report on current activities in real time and provide current summary data and a summary report (s) for welding, coating and surveillance operations. The uLog system can control the version of system parameters and roll back. The uLog system also provides a single point of data logs, machine setup information and software versions. In yet another embodiment of the invention, integral marking of the pipe connection can be obtained and synchronized with the data logs.

[001261] In FIG. Figure 160 shows an example of a GUI for the Welding Parameters screen of the application for cloud universal data logging (uLog), showing two different mechanisms for choosing the type of function to be performed (for example, obtaining welding parameters (PS), setting welding parameters (PS), and viewing welding parameters of PS ...) in accordance with an embodiment of the present invention. In one embodiment of the invention, the uLog cloud-based logging system can perform any of the following actions and / or processes: obtain welding parameters, set welding parameters, view and process notes of welding parameters, view and process the passage of welding parameters, and roll back welding parameters. In one embodiment of the invention, uLog may comprise any, several, or all of the following: Remuneration (reward) functionality for pipeline miles, pipeline miles functionality, uLog functionality, M2O functionality and O2M functionality.

[001262] The welder or welding technician may waste the welding wire unnecessarily if the welder replaces the coil too soon before most of the wire is used up. In addition, the welding process may be interrupted if the wire ends during the welding process on the coil, which will lead to downtime and the need to eliminate the defect. One way to solve these problems in the present embodiment is to follow the wire feed motor speed to determine the wire feed speed and, therefore, determine the length of the welding wire that is consumed over a certain period of time. However, this method may contain errors due to slippage of the wire on the wheel of the wire feed motor or incorrect starting weight. As a result, determining wire lengths based on motor speed may be inaccurate. In addition, an incorrect initial weight may cause the user to believe that there is enough wire in the coil for welding (if the initial or initial weight exceeds, for example, an estimated), while in fact the amount of wire remaining in the coil is not enough to complete welding. To eliminate this drawback, a device is used to measure the mass of the coil of wire in real time, while the engine pulls the welding wire. By measuring the weight of the coil, the user or welder, before starting welding, can determine if enough wire remains in the coil to complete the welding. As a result, the weight of the wire can be determined at any time, which significantly eliminates the uncertainty due to slippage or unknown initial coil mass. In addition, the weight can be compared with the wire feed speed to determine if the wire feeds at a given speed.

[001263] In FIG. 161A schematically shows an example of a coil 14480 that is configured to hold a welding wire in accordance with an embodiment of the present invention. In FIG. 161B is a schematic side view of a hub sensor 14482 that is configured to measure the mass of a coil 14480 according to an embodiment of the present invention. In FIG. 161C is another side view of a hub sensor showing an arrangement of sensor elements or strain gauges / gauges 14484 for measuring strain under load when coil 14480 is mounted on hub 14482 in accordance with an embodiment of the present invention. As shown in FIG. 161B, when the coil is mounted on the hub 14482, the weight of the coil will exert a force on the axis 14482A of the hub 14482, which in turn will cause deformation of the side of the hub 14482B. Deformation sensors 14484 are provided on the side of the hub 14482B to detect deformation resulting from the weight of the coil. Examples of strain gauges that can be used to measure strain are piezoelectric elements. Deformation sensors 14484 convert the deformation force into a measured voltage. Therefore, by measuring the voltage, it is possible to determine the weight of the coil 14482. In one embodiment of the invention, a temperature sensor (not shown) may be provided in the hub so as to obtain hub temperature data to apply corrections to the strain gauge measurements for a wide temperature range.

[001264] In FIG. 162 is a schematic diagram in which welding wire 14486 in a coil 14480 mounted on hub 14482 is pulled by a propulsion system 14490 to feed wire 14482 to a welding device (not shown) in accordance with an embodiment of the present invention. Welding wire 14486 is pulled by a propulsion system 14490. In one embodiment of the invention, the speed of rotation of the propulsion system (used to determine the wire feed speed) can be measured by a sensor 14492. In one embodiment of the invention, the propulsion system uses an engine with an appropriate speed of rotation (speed in minute or RPM, measured by sensor 14492) to achieve the desired wire feed speed to the welding device. In another embodiment of the invention, the rotation of the propulsion system can be changed in accordance with the required wire delivery speed (wire feed speed) measured by the sensor 14492. The engine installation 14490 is configured to feed or supply the welding wire 14486 to the welding device 14500 for welding the workpiece 144101 ( e.g. pipes, etc.). The speed of the welding device 14500 is measured by a speed sensor 14502. The speed sensor 14502 is also configured to measure various welding parameters or welding data.

[001265] In FIG. 164A and 164B show enlarged cross-sections of a propulsion system 14490 according to an embodiment of the present invention. As shown, the propulsion system includes an engine 14491 and a feed wheel 14493. The engine 14491 is engaged with the feed wheel 14493 so as to rotate the feed wheel 14493. The propulsion system 14490 further includes a pinch roller 14495 that comes into contact with the feed wheel 14493. A tension spring 14497 is provided to bias the pinch roller 14495 to the feed wheel 14493. Welding wire 14486 is located between the feed wheel 14493 and the pinch roller 14495. Consequently, the pinch roller 14495 presses the wire at 14486 to 14486 lead wire in contact with the feed wheel 14493. As a result, rotation of the feed wheel and the pressure roller 14493 14495 as shown by arrows in FIG. 164B will be translated, in theory, into linear movement of wire 14486, as shown by the arrow. In one embodiment of the invention, teeth are provided on the feed wheel 14493 so as to grip the wire 14486 by friction and cause the wire 14486 to move. However, situations may arise where wire 14486 is not completely trapped by feed wheel 14493. In this case, wire 14486 can slip because even though feed wheel 14493 rotates, this rotation of feed wheel 14493 does not translate into exact linear movement of wire 14486. For example, this this can happen if the teeth on the feed wheel 14493 are worn out (thus, there is not enough friction to grab the wire 14486), or when the pinch roller 14495 is worn out (it does not exert enough pressure or force on wire 14486 to press wire 14486 against feed wheel 14493), or when tension spring 14497 loses its initial tension (thus causing pinch roller 14495 to not exert enough pressure or force on wire 14486) or when nut 14499 holding feed wheel 14493, loosens (which leads to the fact that the feed wheel does not grab the wire 14486), or any combination of the above. As shown in FIG. 164A, the propulsion system 14490 includes a speed sensor 14492, which is configured and configured to be located for measuring the speed of the engine 14491. An output device 14498 is provided for inputting and outputting data to the propulsion system 14490 and from the propulsion system 14490, data include an engine speed of 14491. Data received from an output device 14498 is sent to a computer 14416 connected to a welding station 14410.

[001266] FIG. 165 is a configuration diagram of a welding system depicting interconnections of various components of a system in accordance with an embodiment of the present invention. As shown in FIG. 165, the rotational speed of the propulsion system 14490 is measured by a rotation speed sensor (RPM sensor) 14492. In addition, the weight of the welding wire coil 14480 is measured by a weight sensor (s) 14484 in the hub sensor 14482. The speed of the welding device 14500 is measured by a speed sensor 14502. All parameters or data measured by the speed sensor 14492, weight sensor 14483, and speed sensor 14502 are input to computer 14416 at welding station 14410. In one embodiment, computer 14416 can be controlled by intermediate computer 14450. The intermediate computer 14450 can be a wireless device, such like tablet, mobile device, smartphone, laptop, etc. Therefore, the intermediate computer 14450 can access the data on the computer 14416, including data from the RPM sensor 14492, the weight sensor 14484, and the speed sensor 14502. The intermediate computer 14450 further exchanges data (for example, using wireless technology) with a cloud server 14432, where data from the computer 14416 can be stored and / or further processed. In one embodiment of the present invention, an intermediate computer is not used. In this case, the computer 14416 directly connects (for example, using wireless technology) to the cloud server 14432.

[001267] As indicated in the above paragraphs, due to potential slippage, measuring a propulsion system speed (eg, feed wheel speed 14493) in some embodiments may not be sufficient to provide the exact amount of welding wire that is used or consumed by the welding machine or system. Indeed, even if the rotation of the feed wheel 14493 is accurately measured, the rotation of the wheel will be translated, theoretically, into movement and, therefore, into a certain length. However, due to slippage, the wire does not move, and therefore, the length determined based on the rotation or the rotation speed of the wheel does not correspond to the actual length of the wire. As a result, the weight of the welding wire coil can also be measured. In one embodiment of the invention, the weight of the new and unused wire spool is about 15 kg (15,000 g). In one embodiment, the weight of the coil of wire is measured with an accuracy of about 100 g per 15,000 g, that is, with an accuracy of about 0.7%. Therefore, weight provides a relatively good measurement method for determining the amount of welding wire remaining in the coil. In one embodiment of the invention, the weight of the coil is obtained or measured periodically and recorded with a time stamp and reported to uLog each time the rotation of the coil is stopped. An indicator, such as a buzzer or a flashing light or the like, may indicate to the welder that it is time to reload another coil. In addition, in one embodiment of the invention, the welding machine cannot start a welding operation in such a situation. The indicator may indicate a weight threshold at which a full weld cannot be completed.

[001268] In one embodiment of the invention, RF modules are additionally provided for reading the serial number of the coil, the mass of the coil from the manufacturer, the type of coil, project name and any parts that are placed on the RF tag mounted on the coil. This data can be transmitted in the cloud via uLog with any additional details. If the old coil is reused, the system compares the serial number with a database of the coils already used and extracts the last available weight from the cloud, comparing it with the new weight reading before starting work. A buzzer or indicator is possible in the system, indicating to the operator that the details of the RF tag have been read and transmitted via CAN. Using the RF system will eliminate any manual accounting work necessary to track the number of coils used, their serial numbers and further identification of the workstations on which they are used. In the case of sending a welding wire with the wrong composition / diameter, the system can identify this by the RF tag properties, warning the operator about this deviation. This may go unnoticed if the system was completely manual.

[001269] In one embodiment, the difference DW between the mass W1 measured at time T1 and the mass W2 measured at a later time T2 can be calculated. The difference in DW weight (where DW = W1-W2) corresponds to the weight of the wire that was used up during the welding process. This difference in DW weight can be compared with the theoretical mass TW. Theoretical weight TW can be obtained using motor rotation speed R or linear wire speed S (linear speed S depends on rotation speed R). The theoretical weight TW can be calculated using the following equation (1).

TW = (T2-T1) x S x (Wire diameter) 2 x (Density of the wire material) x π / 4 (1)

[001270] If, suppose there is no slippage, the theoretical weight TW should be equal to the measured mass DW. On the other hand, if slippage occurred during the process between time T1 and time T2, the theoretical mass TW will be greater than the measured mass DW. In this case, the ratio R between the theoretical mass TW and the measured mass DW is greater than 1 (R = TW / DW> 1) and / or the difference Δ between the theoretical mass TW and the measured mass DW is greater than zero (Δ = TW - DW> 0) . As a result, if after a certain period of time or the number of measurements it is noted that the difference between the measured mass and the theoretical / calculated mass is maintained, the speed of the propulsion system 14490 can be adjusted or compensated to have a calculated / theoretical mass substantially equal to the measured mass. Therefore, the measured mass is compared with the theoretical mass (determined by the wire feed speed) to determine if the wire is fed at the estimated wire feed speed. In one embodiment of the invention, this determination can be made locally on the welder side or using the uLog system on the 14432 cloud server.

[001271] FIG. 163 is a flowchart depicting a process of comparing a measured mass and a theoretical mass determined based on a wire feed speed according to an embodiment of the present invention. As can be understood from the above paragraphs, the process starts by measuring the first wire coil mass W1 for the first time (T1) in step S10. This method further includes measuring a second coil mass W2 a second time T2 after some time elapsed from time T1 in step S12 (T2> T1). This process also includes calculating the difference between the first measured mass W1 and the second measured mass at time T2 in step S14. The process includes calculating the theoretical mass based on the wire feed speed in step S16. In step S18, the theoretical mass based on the wire feed speed is compared with the calculated mass difference, and if the theoretical mass is larger or smaller than the calculated mass difference, in step S18, the speed of the propulsion system pulling the wire is adjusted in step S20. The process is repeated after another time step, after the speed of the propulsion system is adjusted. If the theoretical mass coincides with the calculated difference in mass, then the process also repeats after another time step without adjusting the speed of the propulsion system. This process is repeated with many time steps to monitor and / or correct any possible slippage of the 14490 propulsion system.

[001272] This process can be locally implemented by the uLog system on a computer 14416 connected to the welding station 14410 or implemented by the uLog system on a cloud server 14432 or implemented by the uLog system on an intermediate computer 14450 described in the previous paragraphs.

[001273] In one embodiment of the invention, it may be desirable to control the use of wire at different welding stations 14410 to evaluate the overall efficiency of the welding system. For example, this will allow a prognostic indication of the coil volume required for large projects based on previous knowledge. For example, coil utilization data can be uploaded to the uLog system, stored and processed by the cloud server 14432. For example, each of the welding stations 14410 can upload coil utilization data to the uLog system on a cloud server using the network configurations previously described and based on historical usage data. the number of coils for wire and the use of machine learning algorithm (AMO), the uLog system can predict the average future use of coils for wire (or the number of welding wires s). For example, based on usage patterns for some welding parameters, the uLog system can determine the threshold at which a full weld cannot be completed. As a result, the uLog system can warn the welder with an indicator (for example, a buzzer, flashlight, etc.) that the wire in the coil has been exhausted and that the full weld cannot be completed based on the theoretical threshold determined using the machine learning algorithm. For example, a cloud server 14432 running uLog may be configured to provide feedback to one or more of the plurality of welding station computers 14416 to warn the welder that a full weld cannot be completed based on a theoretical threshold determined using learning algorithm machines.

[001274] In another embodiment, when there is a discrepancy between the theoretical mass determined based on the wire feed speed (measured by sensor 14492) and the measured mass (W2-W1), where W2 and W1 are measured by weight sensors 14484, instead of adjusting the speed of the propulsion system 14490 the speed of the welding device 14500 (or the speed of movement) can be adjusted in accordance with the speed V obtained from the measured mass W2-W1.

[001280] In FIG. 166 shows an overview of a system that can be used with a wide range of testing and surveillance equipment, tools, processes, and methods. In the general example of FIG. 166, a pipeline 16610 may be constructed as directed by the owner 16670 by joining multiple pipe segments together using ring welds. This design may be performed by the owner company, a third party, or another party. As part of the quality management parameters, non-destructive testing and supervision can be carried out during the construction process to ensure that the pipeline does not fail when performing its specific service. To ensure this, for example, one or more welds, such as ring welds, can be checked and tested by one or more testing means, processes or methods, such as ultrasonic inspection or radiographic inspection.

[001281] For example, field worker 16650 may place a test device, such as image processing device 16620 in a pipeline, in the immediate vicinity of each of the ring welds. A test device, which may be an image processing device, can collect data related to the internal structure of the annular weld for analysis. This data may be any type of data necessary for analysis by an inspector or other person, or necessary for any computer processing. For example, if an ultrasonic inspection method or an X-ray inspection method is used, or both, one or more signals can be transmitted to the pipe and / or weld, for example, an annular weld, and data and information in response to such signals can be collected, processed and analyzed by one or more computers and / or one or more people.

[001282] In one embodiment of the invention, responses to signals can be received, processed, digitized, compressed, transmitted and communicated (16625) to a separate device or receiver (or which can be separated from a test device that generates a signal (s) and / or receives response (s), which can be located at a remote location or at a remote site 16630. In this document, a device, object or computer that receives data from the test unit and which is separate or can be separated The flax from the test unit will be called the “remote object.” The remote object broadly covers any device, object or person, or anything else that can receive, use, perceive, process or transform any data received from the test unit. This term can range from a storage device, such as a memory card, to a distributed control system, cloud processor, mobile phone, smartphone, computer, digital processor, receiver, function noy possible, the control system at the plant level or remote facility, or a remote central processing unit or other human or location. In one embodiment of the invention, the remote site may be a remote facility, which may be a center for computing, processing, and monitoring. A remote object, such as a remote installation, can be connected to a network, a wireless network, based on cloud technologies, based on hybrid cloud technologies, or located on a physical object or associated with a person, company, functionality, use, entity or other. In one embodiment of the invention, the remote site may be owned and / or controlled by any person, customer, company, organization, inspector, third party, operator, employee or other.

[001283] In one embodiment, a remote site, such as a remote installation, can use a computer to process test and / or control data, such as compressed data, to determine the size, shape, location, and orientation of any defects present in the weld and / or pipe. Test data and / or control data or analytical results may be reported (16635) to the control specialist 16640, who may verify the data or verify the analytical results, or otherwise use all or part of the data provided to the control specialist 16640. In this document, “test data” and “non-destructive testing data” are used synonymously. As an example, the result or results verified by the inspection specialist can be reported (16645) to field worker 16650. This provides support for repairing defects or controlling repair processes for defects in welds and pipelines. Optionally, verified results can be communicated to the inspector of 16660 Quality Assurance and the owner of 16670.

[001284] The technologies, processes, tools and methods used herein can be distributed and used for testing and inspection of pipes. The equipment, processes, and devices described herein have applications that extend far beyond welds.

[001285] In FIG. 167 shows an embodiment of a system that can be used with any of a variety of different testing techniques and with many types of equipment. As shown in FIG. 167, in an embodiment of the invention, one or more annular welds can be checked. The 167110 ring welds that connect the 167100 pipelines together can be inspected before the pipeline is put into operation. One representative of operating personnel 167500 or many representatives of operating personnel 167500 can move along a pipeline having one or more annular welds 167110. They can stop at each ring weld and use the equipment 167200 for image processing to obtain images of the internal structure, respectively, one or more of the ring welds 167110. The number of ring welds 167500 to be checked can vary from 1 to very large values, for example, up to 5 million.

[001286] The data and images obtained as a result of the verification can be generated, processed, recorded, detected, digitized, compressed and transmitted on site or to a remote object, such as a remote central object 167300. At a remote central object 167300, computer 167310 can process the data and images obtained as a result of verification (which may be digital images or another data image or data set) to determine the size, shape, orientation and location of any defects, existing in a tested weld. By executing executable computer code using computer executable logic, the computer can also determine which defects are significant enough and / or large enough to have a significant effect on the integrity of the pipeline. If the defect is identified by computer processing, one or more defects can be referred to a 167400 control specialist who can verify the presence and significance of the computer-detected defects.

[001287] Alternatively, the inspector can directly view the data obtained from the audit and conclude about the inspector’s training and experience. Optionally, inspector findings can be verified by computer processing.

[001288] The verified results, both computer-generated and human-generated, can then be transmitted to 167500 field workers by computer or telephone so that welds can be repaired. The results of the inspection can also be sent to the inspector of the quality assurance service 167600, the company-owner of the pipeline 167700, or other interested or prospective party.

[001289] In one embodiment, a pipeline 167100 can be constructed as directed by the owner 167700 by connecting multiple pipe segments 167120A, 167120B using ring welds 167110. To ensure that the pipeline does not fail during operation, it is desirable that the builder or other specialists tested annular welds with non-destructive means. These tools may include magnetic particle testing, penetrating dye control, ultrasonic testing, and x-ray radiography. Both methods - ultrasonic testing and x-ray radiography - are methods of image processing with heavy use of data.

[001290] Analytical work to evaluate test data and / or control requires one or more highly qualified specialists 167400, 167520 and specialized image processing equipment 167200. The image processing equipment that can be used may have an emitter 167210, a receiver 167220 and similar 167230 digital (A / D) converter. One or more 167520 field workers can transport 167200 image processing equipment to the weld along the pipeline using a 167530 truck support, or another vehicle.

[001291] The image processing equipment may be of any suitable type, such as ultrasound or radiography.

[001292] In a segmented connection, field workers can place image processing equipment on or near the pipeline near the ring weld 167110. A field worker can activate image processing equipment. The radiating part may send a signal (167215) to pipe segments and / or an annular weld. The signal may be pulses of an ultrasonic wave in the case of ultrasonic testing, or may be x-ray in the case of x-ray radiography.

[001293] In the case of ultrasonic testing, ultrasonic pulses can reflect the boundaries where the density of the ring weld 167110 changes. The boundaries between metal and air give the strongest reflections. The reflected pulses can be detected by the receiver. The receiver can measure the intensity of the reflected pulse (167222) and can generate an electronic signal proportional to the intensity of the reflected pulse. In one embodiment of the invention, the emitter and receiver may have several elements. Optionally, the emitter elements can be selectively activated to set an ultrasonic pulse at a specific location.

[001294] In the case of x-ray radiography, the x-ray intensity is attenuated by the material in the pipe segments and the annular weld. The receiver can measure the intensity of the radiation that passes through the material (167224).

[001295] In one embodiment of the invention, image processing equipment can be mounted on a motor-driven carriage that can move along the circumferential seam at a constant speed. An analog-to-digital converter can digitize the signal (167226) from the receiver and can compress the digitized data. The compressed image processing data and the location of the carriage (167235) can be transmitted to the 167310 computer at a remote location, such as the 167300 remote installation. Data can be exchanged via cable, moving physical storage media, wirelessly, networked, cloud, radio or other means .

[001296] In a non-limiting example of FIG. 167, on a remote installation of 167300, computer 167310 can analyze the data (167235). The analysis can be performed in one or more stages. For example, compute module 167320 can identify signals (167222, 167224), which may indicate the presence of anomalies in the annular weld 167110. Anomalous signals (167325) can be transmitted to the module 167330 AI. The AI module may be a computer on which executable computer code, relational logic, and / or artificial intelligent programming are executed. The AI module can determine the size, shape, orientation, and location of defects (167335) that caused abnormal signals (167325). The AI module can execute executable computer program code using logic based on a system of rules to determine which defects are important for pipeline integrity and which need to be repaired and which are not. Computer 167310 can send data (167335) describing zero or more defects to the technician 167400, the inspector of the quality assurance service 167600, the company owner 167700, as well as the representative of the operating personnel 167500 or other persons.

[001297] In one embodiment of the invention, the control specialist may select data (167335) for verification (167215) before it is transmitted to the quality assurance service inspector, the owner company, a representative of the operating personnel, or other persons. A control technician can also change the identification of a defect from significant to non-essential or from non-significant or significant, or otherwise change or annotate any results obtained by a computer or otherwise. Defect data (167335) that are associated with a significant defect can be transferred to a 167500 operating personnel representative. Data can be transferred to one or more field workers 167520. One or more field workers can mark the locations and sizes of significant defects on the weld (s) and / or on a pipeline (167525) for repair by the welder 167510 or by others. Alternatively, the data may be transferred directly to the repair welder 167510 or other persons.

[001298] In FIG. 168 shows an embodiment of ultrasonic testing. As shown in FIG. 168, in an embodiment of the invention, one or more annular welds can be checked by ultrasonic testing. Ring welds 168110, which connect the pipelines 168100 together, can be checked before the pipeline is put into operation. One representative of operating personnel 168500 or many representatives of operating personnel 168500 can move along a pipeline having one or more annular welds 168110. They can stop at each annular weld and use the ultrasonic testing equipment 168200 to obtain images of the internal structure of the weld. These images can be digitized, compressed, and transmitted to a remote installation, such as a remotely located central facility 168300. At a remote central facility, computer 168310 can process monitoring data such as ultrasound data, image data or images to determine size, shape, orientation and the location of any defects present in the tested weld. The number of checked ring welds 168110 can vary from 168 to a very large number, for example, up to 5 million.

[001299] By executing executable computer code using computer executable logic, the computer can also determine which defects are significant enough and / or large enough to have a significant effect on the integrity of the pipeline. If the defect is identified by computer processing, one or more defects can be referred to a 168400 inspection specialist, who can be an ultrasound specialist who can check for the presence and significance of the computer-detected defect.

[001300] Alternatively, the inspector can directly view the data obtained from the audit and conclude about the inspector’s training and experience. Optionally, inspector findings can be verified by computer processing.

[001301] The verified results, both computer-generated and human-generated, can then be transmitted to a representative of the operating personnel 168500 using computer tools or over the phone so that welds can be repaired. The results of the inspection can also be sent to the inspector of the quality assurance service 168600, the company-owner of the pipeline 168700, or other interested or prospective party.

[001302] In one embodiment of the invention shown in FIG. 168, pipeline 168100 is constructed as directed by the owner of 168700 by connecting multiple segments of 168120A, 168120B of pipes together using ring welds 168110. To ensure that the pipeline does not fail during operation, it is desirable that the ring welds be checked by non-destructive testing. These tools may include magnetic particle testing, penetrating dye control, ultrasonic testing, and x-ray radiography. Ultrasonic testing is an image processing technique with heavy use of data. This requires one or more highly qualified specialists 168400, 168520 and specialized equipment 168200 for image processing.

[001303] The image processing equipment may have an emitter 168210, a receiver 168220 and an analog-to-digital converter 168230. One or more field workers 168520 can transport image processing equipment 168200 along the pipeline using a support truck 168530, or another vehicle. Field workers can place imaging equipment in a pipeline near the 168110 ring weld, on the ring weld that needs to be inspected. A field worker can activate imaging equipment. The radiating part can send ultrasonic pulses (168215) to pipe segments and an annular weld. Pulses can be sent in the range from 1 Hz to 20,000 Hz. The frequency of the ultrasonic wave can vary from 0.5 MHz to 23 MHz. Ultrasonic pulses can reflect boundaries where the density changes in the 168110 ring weld or in the pipe. The boundaries between metal and air give the strongest reflections. Reflected pulses can be detected by the receiver. The receiver measures the intensity of the reflected pulse (168222) and creates an electronic signal proportional to the intensity. The emitter and receiver may have several elements. The emitter elements can be selectively activated to set the ultrasonic pulse at a specific location.

[001304] The image processing equipment is mounted on a motorized carriage, which can move along the circumferential seam at a constant speed. An analog-to-digital converter can digitize the signal (168226) from the receiver and can compress the digitized data. The compressed image processing data and the location of the carriage (168235) can be transferred to a remote object, for example, a computer 168310, which may optionally be located on a remote object 168300. Data can be exchanged via cable, moving physical storage media, wirelessly, networked, cloudy technology, radio or other means.

[001305] In one embodiment of the invention shown in FIG. 168, on a remote installation of 168300, computer 168310 can analyze the data (168235). The analysis can be performed in stages. Computing module 168320 can identify signals (168222), which may indicate the presence of anomalies in the annular weld 168110. Anomalous signals (168325) are reported to the module 168330 AI. The AI module can determine the size, shape, orientation, and location of defects (168335) that caused abnormal signals (168325). The AI module can determine which defects are significant to the integrity of the pipeline and should be repaired. Computer 168310 sends data (168335) describing zero or more defects to the technician 168400, the inspector of the quality assurance service 168600, the company owner 168700, the representative of the operating personnel 168500 or other persons.

[001306] Optionally, the control technician can directly receive data and conduct analysis separately from the AI. Optionally, in this case, the control specialist can use AI to verify or confirm the results of the technical inspection.

[001307] Optionally, the control specialist may select data (168335) for verification (168335) before transmitting it to the inspector of the quality assurance service, the owner company, a representative of the operating staff, or other persons. A control technician can also change the identification of a defect from significant to non-essential or from non-essential or significant.

[001308] Defect data (168335) that are associated with a significant defect can be transferred to a representative of operating personnel 168500. Data can be transferred to one or more field workers 168520. One or more field workers can mark the places and sizes of significant defects in the pipeline (168525 ) for subsequent repairs by the welder 168510. Alternatively, the data may be transferred directly to the repair welder 168510.

[001309] In FIG. 169 shows an embodiment of an x-ray control. As shown in FIG. 169, in an embodiment of the invention, one or more annular welds may be checked by radiographic inspection. Ring welds 169110, which connect the pipelines 169100 together, can be checked before the pipeline is put into operation. One 169500 operating representative or many 169500 operating personnel may move along a pipeline having one or more ring welds 169110. They may stop at each ring weld 169110 and use x-ray equipment 169200 to collect data and / or obtain an image of the internal structure of each annular weld 169110.

[001310] Inspection data and / or images can be digitized, compressed, and transmitted to a remote object, such as a remotely located central object 169300. At a remote central object, computer 169310 can process monitoring data such as ultrasound data, image data or images so that Determine the size, shape, orientation and location of any defects present in the tested weld. The number of checked ring welds 169110 can vary from 1 to a very large number, for example, up to 5 million.

[001311] By executing executable computer code using computer executable logic, the computer can also determine which defects are significant enough and / or large enough to have a significant effect on the integrity of the pipeline. If the defect is identified by computer processing, one or more defects can be referred to a 169400 control specialist, who can be a radiographic control specialist who can check for the presence and significance of the defect detected by the computer.

[001312] Alternatively, the inspector can directly view the data obtained from the audit and conclude the experience of the inspector. Optionally, inspector findings can be verified by computer processing.

To ensure that the pipeline does not fail during operation, it is desirable that the ring welds be checked by non-destructive testing . These tools may include magnetic particle testing, penetrating dye control, ultrasonic testing, and x-ray radiography. Both methods - ultrasonic testing and x-ray radiography - are methods of image processing with heavy use of data. They require one or more highly qualified specialists 169400, 169520 and specialized equipment 169200 for image processing. The image processing equipment may include an emitter 169210, a receiver 169220 and an analog-to-digital converter 169230.

The AI module can determine the size, shape, orientation, and location of defects (169335) that caused abnormal signals (169325). The AI module can determine which defects are significant to the integrity of the pipeline and should be repaired.
