Description
Technical field:
The invention belongs to technical field of welding equipment, and in particular to a kind of spot welding contra-aperture device and right for pipe aligning welding
Mouth method.
Background technique:
It is embedded in the pipeline on underground and ground for oil transportation or water delivery and the phenomenon that perforating because of corrosion often occurs, pipeline of perforating
Processing mode is mainly to change this section of perforation pipeline of seriously corroded, i.e., cuts down the perforated pipe section, then will be isometric
The new pipeline substitution perforated pipe of one section of degree is connected to whole pipeline by welding.The new pipeline of equal length needs twice weld bond real
The docking of existing pipeline usually first welds one end of certain section of new pipeline and one end of disconnected pipe, then by the other end of new pipeline and
The other end welding of disconnected pipe.But due to the external force such as buried stress, be embedded in for a long time underground pipeline be cut off one section after, by
External carbuncle is generated in reasons such as soil matrix depositions, so that two pipelines being disconnected are no longer concentric；It is disconnected after i.e. buried pipeline disconnects
Mouthful misplace, horizontal buried pipeline disconnect after dislocation as shown in Figure 1, dislocation such as Fig. 2 institute after vertical buried pipeline disconnection
Show.It is not only buried horizontal and vertical pipeline and fracture dislocation, the horizontal pipeline on ground and vertical pipeline occurs upon opening
There is fracture inconsistent phenomenon in welding stress or other external force when can be because of connecting pipeline, such as the ground between petroleum metering or between station
Pipeline, one end are the long-distance transport pipes for being embedded in underground, and the equipment such as rear pump between the other end and station connect, the pipeline connected in this way
Inconsistent phenomenon can all occur after fracture.
Currently, the pipe string of corrosion failure is cut, the new pipe of about equal length is reused in processing pipeline perforation
Wire bonding replacement perforation pipeline, the length of new pipeline need the actual measurement that needs according to site welding, length substantially with cut
The length of underground pipelines is identical.When to pipe welding, first new pipeline and one of fracture are welded, before first of weld bond of welding
New pipeline tool there are two free end, the one end that need to only hold new pipeline makes the pipeline of two butt welding about i.e. solderable with one heart
It connects, usually first on the circumference of pipeline opposite joint at least at spot welding two, new pipeline is fixed with this, then carry out the welding of opposite joint.Weldering
Second weld bond is welded again after having connect first of weld bond, due to above-mentioned fracture inconsistent phenomenon, when welding last one of weld bond,
It needs to correct the pipeline both ends of dislocation using external force, be allowed to as far as possible with one heart, or guarantee as far as possible to being sewn on a cylindrical surface
On, to guarantee welding quality；When to positive weld bond, usually multiple operators agitate one of dislocation pipeline using crowbar
Or agitate two dislocation pipelines simultaneously so that the fractures of two dislocation are being as far as possible to just, at this moment welder immediately to docking weld bond into
Row spot welding selects the quantity of spot welding point according to the size of stress, after docking pipeline spot welding is fixed, withdraws from crowbar and carries out opposite joint again

Mouthful when not can guarantee opposite joint can be farthest to just, in addition, pipe aligning fully relies on manpower to realize, artificial origin couple
The quality of counterpart influences, and welder can not judge whether opposite joint correction is optimum state, weldering
Work can only carry out spot welding in the case where no counterpart as far as possible and fix, and carry out opposite joint according to the pipeline aligned position of the spot welding
Welding, the pipeline magnitude of misalignment of butt welding is larger at this time, influences welding quality, and welding quality is low, the biggish counterpart weldering of magnitude of misalignment
It connects, is easily corroded at welding junction, and significantly misplace due to being generated at the counterpart of pipeline inner hole, cause at the counterpart
It is easy deposition sundries, especially as petroleum pipeline in use, being easy to gather the dirty matter such as oily wax, influences the flow and pressure of pipeline；
(4), safety is poor, and when using crowbar counterpart, crowbar is easily slided, and causes operator that can fall down or collide with suddenly,
There are serious security risks；(5), application range is limited, if carrying out welding counterpart to buried pipeline, needs to dig out biggish behaviour
It cheats, so that counterpart operation smoothly completes, increases construction cost, it, can not if carrying out welding counterpart to ground vertical tube line
Welding counterpart is realized using crowbar, and surface line do not operate hole, the just not no supporting point of crowbar yet, at this moment can only pass through dragging
The mode of traction rope carries out welding counterpart, this extremely difficult operation of mode, and the welding quality of opposite joint is extremely low.In addition, in weight after disconnected pipe
Newly weld new pipeline and be not only used for pipeline corrosive perforation, be also applied to it is other needs again welded pipeline the case where, such as
Face, underground utilities transformation or metering room transformation etc. need pipeline to meet and discuss the case where docking, for another example because of pipe network water delivery or oil transportation
It needs to remove the valve of surface line into situations such as not having to, needing to be connected to the pipe network of split valve using pipeline.
