BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to welding technology, and more particularly, to a welding management system capable of performing welding work through integrated management and a method therefor.

MIG welding is a type of gas metal arc welding (GMAW) that uses inert gas (Ar, He) to shield arc or molten metal from air, Refers to welding that welds a wire with an arc heat while supplying the welding wire from the nozzle of the torch at a constant speed. During welding, the gas ionizes and collides with the surface of the base material from the electrode to remove the oxide film on the surface, which is suitable for light alloy welding such as Al and Mg. In addition, a smooth and beautiful bead appearance with a high current density can be obtained. It has the advantage of being able to easily weld in any position such as below view, vertical view and upper view. It is highly efficient compared with TIG welding and mainly used for welding thick plate of 3mm or more.

A laminated composite in which two or more metal surfaces are metallurgically bonded together is referred to as clad material, and the process of making such a clad material is called cladding.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention, and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that, in the drawings, the same components are denoted by the same reference symbols as possible. Further, the detailed description of known functions and configurations that may obscure the gist of the present invention will be omitted. For the same reason, some of the elements in the accompanying drawings are exaggerated, omitted, or schematically shown, and the size of each element does not entirely reflect the actual size.

First, a welding system according to an embodiment of the present invention will be described. 1 is a block diagram for explaining a welding management system according to an embodiment of the present invention. Referring to FIG. 1, a welding system according to an embodiment of the present invention includes a welding apparatus 100, a management device 200, and a management server 300.

The management server 300 is an apparatus for communicating with the welding apparatus 100 and the management apparatus 200 to manage overall matters related to the welding operation. The management server 300 is a computing device capable of performing computing operations and performing wired / wireless communication. For management purposes, the management server 300 may store all welding information associated with the welding operation. Such welding information includes information on the object to be welded and information on the material used in the welding. The welding information further includes a set value of a welding parameter for setting a welding condition, a measured value of a welding parameter that is measured in actual welding and indicates a welding condition, and welding error information when a welding defect occurs. Some examples of such welding information are shown in Table 1 below.

Welding Welding parameters Setting value Measures video Weld error record Welding 1 Welding parameters 1 Setting value a Measured value l Image 1 log1 Welding parameters 2 Setting value b Measured value m Video 2 log2 Welding parameters 3 Setting value c Measured value n Video 3 log3 ... ... ... ... ... ... ... ... ... ... ...

In particular, the management server 300 sets the welding conditions through the set values for all the parameters that can be controlled at the time of welding. When setting the welding conditions, the management server 300 receives the set values of the welding parameters from the management device 200, and stores the set values of the welding parameters in the database. In addition, the management server 300 provides the stored set values to the welding apparatus 100 so that the welding apparatus 100 performs the welding according to the set values.

In addition, the management server 300 receives the measured values from the welding apparatus 100 for the welding parameters during the welding operation, and then stores the received measured values. In particular, when a welding defect occurs at the time of welding, the welding apparatus 100 receives from the welding apparatus 100 an image including a position at which a welding defect has occurred, a measured value for the welding parameter, and a thermal image and a general image. In this way, the management server 300 can store all the welding-related information (welding information). If there is a request from the management apparatus 200, it can provide all the stored data according to the access authority. In addition, the stored welding information can be stored in the welding record according to a predetermined format. Accordingly, the welding record can be provided to the management apparatus 200 by the access authority at the request of the management apparatus 200. [ In addition, the weld record may be output through a device for outputting and displaying, e.g., a display, a printer, and the like.

The welding apparatus 100 is an apparatus for actually performing welding with respect to the welding object 1, and includes a welding machine for welding, a robot for moving the welding machine so that the welding machine performs welding for a specific position, A recording medium for storing information, and a camera / monitoring module for shooting a thermal image, a general image, and the like at the time of welding. When the welding apparatus 100 receives the welding parameter setting value from the management server 300, the welding apparatus 100 performs the welding according to the received setting value. In addition, the welding apparatus 100 may transmit the measured values of the measured welding parameters to the management server 300 during actual welding. In addition, the welding apparatus 100 can photograph an image including a thermal image, a general image, and the like when welding, and transmit the image to the management server 300.

The management device 200 is a portable device capable of communicating with, for example, a smart phone, a tablet, a tablet, a notebook, and the like. The management apparatus 200 can communicate with the welding apparatus 100 and the management server 300 wirelessly or by wire. The management device 200 transmits the setting value to the management server 300 so that the set value of the welding parameter is set according to the input of the user of the management device 200. [ Also, the management apparatus 200 can access all the information managed by the management server 300 by accessing the management server 300 according to the access right in real time.

The management device 200 may communicate with the welding device 100 to verify overall information about the ongoing welding operation in real time. That is, the management apparatus 200 can confirm the welding state, together with basic information on the welding material used for welding, and information on the welding material. Such a welding state can be confirmed in real time through the measurement value and the thermal image and the general image with respect to the set value of the welding parameter. In particular, when a welding error or defect occurs and the welding apparatus 100 detects this, the welding apparatus 100 provides the management server 300 and the management apparatus 200 with a record related to the occurrence of the welding defect and the welding defect can do. Then, the user of the management apparatus 200 outputs information related to such welding defect, so that the user of the management apparatus 200 can recognize the welding defect in real time. The functions of the above-described management apparatus 200 may be implemented as an application, and the management apparatus 200 may be operated in an app form.

In the embodiment of the present invention, the user can be divided into a first user and a second user. Welding parameters can be divided into several levels according to their importance. Access rights to input, modify, delete, etc. values for the parameters are given differently according to the users. In the embodiment of the present invention, it is assumed that the first user has a higher access authority than the second user. For example, the first user may be the manager of the welding operation and the second user may be the welding engineer. In order to distinguish these access rights, all input, browsing, and modification performed in the present invention may be performed after a login is performed through an identifier (e.g., ID) and a password (e.g., password) for each user.

In the embodiment of the present invention, the welding parameters are various parameters to be applied in welding, and these include basic parameters and additional parameters. The set values of the welding parameters can be set differently depending on the position in the welding object 1. [ The set value of the welding parameter may be a unit time, a maximum value, a minimum value and an average value according to the unit time.

The management apparatus 200 receives the set values of the basic parameters among the welding parameters from the first user, and transmits the set values to the management server 300. Then, the management server 300 will store the setting value. The basic parameters can be current, voltage, speed, etc. during welding. Further, when the management apparatus 200 receives the setting value of the additional parameter among the welding parameters from the second user, the management apparatus 200 transmits the setting value of the input additional parameter to the management server 300. Then, the management server 300 stores the set values. Additional parameters may be the type of protective gas, the flow rate, the maximum and minimum preheat temperatures, and the like.

The welding apparatus 100 receives the set values of the welding parameters from the management server 300, and performs the welding according to the set values. That is, the welding apparatus 100 does not exceed the maximum value and the minimum value of the set values of the welding parameters for the unit time set at the set position, and performs the welding so that the average value is maintained. For example, it is assumed that the specific position is the edge portion of the welding target 1 of the welding apparatus 100, and the unit time is 5 seconds. Further, it is assumed that the welding parameter is the current, and the set value is 220 A, the minimum value is 180 A, and the average value is 200 A. Then, the welding apparatus 100 performs the welding such that the maximum value of the current is 220 A, the minimum value is 180 A, and the average value is 200 A for 5 seconds during the unit time of welding at the edge of the welding target 1 .

Further, the welding apparatus 100 measures and records the measured values for the welding parameters at the time of welding. That is, when the welding apparatus 100 performs welding, a difference may occur as intended by the welding apparatus 100, for various reasons, including environmental influences. Thus, the welding apparatus 100 measures the welding parameters when the actual welding is performed, and records the measured values. The measured value to be recorded can be recorded in the waveform of the welding parameter. For example, when the welding parameter is current, the measured value may be recorded in numerical values and waveforms. In addition to the welding parameters, the welding apparatus 100 can photograph and record thermal images, general images, and the like during welding.

At this time, the welding apparatus 100 can derive the welding defect by comparing the measured value with the predetermined set value and the measured value. For example, it is also assumed that the welding parameter has a maximum value of 220 A, a minimum value of 180 A, and an average value of 200 A for the current. Then, when the current used for welding is more than 200 A, the current used for welding is less than 180 A, and the average value of the current used for welding is 200 A or more If there is a difference, it is judged to be a welding defect. Further, the welding apparatus 100 can detect a welding defect through a thermal image or a general image. If a welding defect is detected, the welding apparatus 100 records the coordinates of the position where the welding defect occurred.

When the welding is completed, the welding apparatus 100 transmits the measured values and the position coordinates of the position where the welding defect occurs to the management server 300. Then, the management server 300 may store the measurement values and the position coordinates of the position where the welding defect occurs, and output the stored data when requested.

Hereinafter, the management server 300 according to the embodiment of the present invention will be described in more detail. 2 is a block diagram illustrating a configuration of a management server according to an embodiment of the present invention. 2, a management server 300 according to an exemplary embodiment of the present invention includes a communication unit 310, an input unit 320, a display unit 330, a storage unit 340, and a control unit 350.

The communication unit 310 performs transmission / reception of corresponding data for wireless communication of the management server 300. The management server 300 can communicate with the management apparatus 200 and the welding apparatus 100 through a communication unit 310 by wire or wirelessly. When communicating wirelessly, the communication unit 310 may include an RF transmitter for up-converting and amplifying the frequency of a transmitted signal, an RF receiver for low-noise amplifying the received signal, and down-converting the frequency of the received signal. Also, the communication unit 310 may receive data from the welding apparatus 100 and transmit the data to the control unit 350. Such data includes welding records and the like. In addition, data transmitted from the control unit 350 can be transmitted. For example, the communication unit 310 receives the setting value of the welding parameter from the control unit 350 and can transmit the setting value to the management apparatus 200 or the welding apparatus 100.

The input unit 320 receives a user's key operation for controlling the management server 300, generates an input signal, and transmits the input signal to the control unit 350. The input unit 320 may include any one of a power key, a number key, and a direction key for power on / off, and may be formed of a predetermined function key on one side of the management server 300. The input unit 320 may represent a keyboard. In the case where the display unit 330 is a touch screen, the function of the input unit 320 may be performed by the display unit 330. In a case where the function of the input unit 320 can be performed only by the touch screen, May be omitted.

The display unit 330 visually provides menus of the management server 300, input data, function setting information, and various other information to the user. The display unit 330 functions to output a screen such as a boot screen, a standby screen, a menu screen, and the like of the management server 300. The display unit 330 may be formed of a liquid crystal display (LCD), an organic light emitting diode (OLED), an active matrix organic light emitting diode (AMOLED), or the like. Meanwhile, the display unit 330 may be implemented as a touch screen. In this case, the display unit 130 includes a touch sensor. The touch sensor senses the user's touch input. The touch sensor may be constituted by a touch sensing sensor such as a capacitive overlay, a pressure type, a resistive overlay, or an infrared beam, or may be constituted by a pressure sensor . In addition to the above sensors, all kinds of sensor devices capable of sensing contact or pressure of an object can be used as the touch sensor of the present invention. The touch sensor senses the touch input of the user, generates a sensing signal, and transmits the sensed signal to the control unit 350. Particularly, when the display unit 330 is a touch screen, some or all of the functions of the input unit 320 may be performed through the display unit 330.

The storage unit 340 stores programs and data necessary for the operation of the management server 300, and can be divided into a program area and a data area. The program area may store a program for controlling overall operation of the management server 300, an operating system (OS) for booting the management server 300, an application program, and the like. The data area is an area where user data generated according to use of the management server 300 is stored. In addition, the storage unit 340 may store various kinds of data generated according to the use of the management server 300 of the user. The data stored in the storage unit 340 may include specifications, set values of welding parameters, welding records, and the like. Each kind of data stored in the storage unit 340 can be deleted, changed, or added according to a user's operation.

The control unit 350 may control the overall operation of the management server 300 and the signal flow between the internal blocks of the management server 300 and may perform a data processing function for processing the data. The controller 350 may be a central processing unit (CPU), an application processor, or the like. The function of the control unit 350 will be described in more detail below.

Although not shown, the management server 300 according to the embodiment of the present invention includes a storage medium inserting unit for inserting an external storage medium such as a memory card to store data, a connection terminal for exchanging data with an external digital device, , And a charging terminal. In addition, the management server 300 may further include units having an additional function such as an audio module for inputting or outputting an audio signal through a microphone and a speaker, and an MP3 module for reproducing a digital sound source. Although the variations of the portable apparatuses vary greatly according to the convergence trend of the digital apparatuses, they can not be all enumerated. However, the units equivalent to the above-mentioned units are further included in the management server 300 according to the present invention It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.

The welding method of the above-described welding system will be described in detail below. 3 is a flowchart for explaining a welding management method of a welding management system according to an embodiment of the present invention.

In FIG. 3, it is assumed that the first user has a higher access right than the second user. For example, the first user may be the manager of the welding operation and the second user may be the welding engineer. In order to distinguish these access rights, all input, browsing, and modification performed in the present invention may be performed after a login is performed through an identifier (e.g., ID) and a password (e.g., password) for each user.

Referring to FIG. 3, the management server 300 stores the set values of the basic parameters in step S110. The management apparatus 200 receives the set values of the basic parameters for welding from the first user and transmits the set values of the input basic parameters to the management server 300. Then, the management server 300 stores the setting values of the basic parameters. The basic parameters can be current, voltage, speed, date, etc., depending on the position of the object to be welded. Further, the set value may be set differently in the welding target 1 depending on its position. The set value of the welding parameter may be a unit time, a maximum value, a minimum value and an average value according to the unit time.

Also, the management server 300 stores the setting value of the additional parameter in step S120. The management apparatus 200 receives the setting values of the additional parameters for welding from the second user and transmits the set values of the input additional parameters to the management server 300. Then, the management server 300 stores the setting value of the additional parameter. These additional parameters may be protective gas type, flow rate, maximum and minimum preheat temperature, and the like. Further, the set value may be set differently in the welding target 1 depending on its position. Here, the position is divided into the coordinates according to the embodiment of the present invention, and the coordinates will be described in more detail below. The set value of the welding parameter may be a unit time, a maximum value, a minimum value and an average value according to the unit time.

Next, the welding apparatus 100 receives the setting values of the welding parameters including the basic parameters and the additional parameters from the management server 300 in step S130. Then, the welding apparatus 100 performs welding in accordance with the set value of the welding parameters in step S140. That is, the welding apparatus 100 does not exceed the maximum value and the minimum value of the set values of the welding parameters for the unit time set at the set position, and performs the welding so that the average value is maintained. For example, it is assumed that the specific position is the edge portion of the welding target 1 of the welding apparatus 100, and the unit time is 5 seconds. Further, it is assumed that the welding parameter is the current, and the set value is 220 A, the minimum value is 180 A, and the average value is 200 A. Then, the welding apparatus 100 performs the welding such that the maximum value of the current is 220 A, the minimum value is 180 A, and the average value is 200 A for 5 seconds during the unit time of welding at the edge of the welding target 1 .

During the welding of the welding apparatus 100 in step S150, the welding apparatus 100 performs measurement on the welding parameters during welding, collects measurement values, and stores the measured values.

At this time, the measured value may be stored together with the numerical value for the parameter, such as the waveform, thermal image, general image, etc., as the welding record. For example, the welding apparatus 100 records the current, voltage, speed, flow rate depending on the kind of the protective gas, maximum and minimum preheating temperatures, and the like, which are used in welding, in numerical values and waveforms. In addition, the welding apparatus 100 stores a thermal image, a general image, and the like as a welding record by using a thermal imaging camera, a surveillance camera, or the like.

Welding defects may occur at certain portions of the welding as described above. Therefore, the welding apparatus 100 determines whether or not a welding defect has occurred in step S160. At this time, the welding apparatus 100 may derive a welding error by comparing the measured value with a predetermined set value and a measured value. For example, it is also assumed that the welding parameter has a maximum value of 220 A, a minimum value of 180 A, and an average value of 200 A for the current. Then, when the current used for welding is more than 200 A, the current used for welding is less than 180 A, and the average value of the current used for welding is 200 A or more If there is a difference, a welding error is judged. Further, the welding apparatus 100 can detect that a welding defect has occurred through a thermal image or a general image. If welding failure occurs, the welding apparatus 100 records the position coordinates of the position.

If it is determined in step S160 that the welding defect has occurred, the welding apparatus 100 stores the measurement value of the welding parameter for the position where the welding defect occurred in step S170 and the coordinates of the position where the welding defect occurred. For example, the object to be welded has positional coordinates in accordance with unit coordinates input in advance, whereby the coordinates of the position where the weld defect occurs are recorded. Then, the welding apparatus 100 proceeds to step S140 and repeats steps S140 through S160. On the other hand, if it is determined in step S160 that the weld defect does not occur, the welding apparatus 100 repeats steps S140 through S160 described above.

On the other hand, the above steps are repeated continuously until the welding is finished. Further, the welding record can be transmitted to the management server 300 during or after the welding is completed. Accordingly, the management server 300 can store and manage the corresponding welding record. If there is a request to browse through the management device 200 or the like, the management server 300 transmits the content to the management device 200. [

Next, a welding method according to another embodiment of the present invention will be described. 4 is a flowchart illustrating a welding method according to another embodiment of the present invention. 5 to 10 are views for explaining a welding method according to another embodiment of the present invention.

Before the start of the welding operation, the object to be welded is determined and the set values of the welding parameters for each part of the object to be welded can be determined. The set values of the welding parameters and the like can be obtained through specifications and the like. According to the embodiment of the present invention, the set values of the welding parameters required together with the drawing of the object to be welded can be inputted according to the specifications. As described above, the set values of the welding parameters can be input by the first user or the second user.

The control unit 350 of the management server 300 assigns the position coordinates to the welding object according to the shape of the welding object on the basis of the drawing of the welding object in step S210. For example, as shown in FIG. 5 (A), the control unit 350 may assign a circular coordinate system to the position coordinates when the welding object is circular. Alternatively, as shown in FIG. 5B, the control unit 350 may assign an orthogonal coordinate system to the position coordinates when the object to be welded is a plane.

Then, the control unit 350 divides the welding object into a plurality of welding areas according to the set values of the welding parameters in step S220. That is, the plurality of welding areas may have different welding parameter setting values. For example, as shown in FIG. 6, the welding target can be divided into the welding areas a to j.

If the welding area of the object to be welded is divided, the controller 350 determines the welding position at which the welding device 100 performs the welding operation for each welding area of each object in step S230. Then, the control unit 350 derives the control coordinates for each of the welding areas from the position coordinates of the welding area in accordance with the welding position and the standard of the welding apparatus 100 in step S240, and stores the control coordinates in the storage unit 330. [ Such a control coordinate may be a robot coordinate system. For example, referring to FIG. 7, the welding apparatus 100, that is, the welding robot, has different motions depending on the shape of its joints (translational, rotational, spherical joints). For example, when the welding apparatus 100 is a welding robot having a rotating joint, the robot hand of the welding apparatus 100 moves along a circle defined in the axis of the joint. Or when the welding apparatus 100 is a welding robot having a translational joint, the robot hand of the welding apparatus 100 has a movement along a straight line defined by the axis of the joint.

On the other hand, the control coordinates are defined differently depending on the position of the welding apparatus 100. 8, in the case where the welding apparatus 100 is a welding robot composed only of joints for translational motion, when assigning the control coordinates to the region d of the welding target 1, the position of the welding apparatus 100 And the control coordinates when the position of the welding apparatus 100 is at N are different from each other. Accordingly, the control unit 350 determines the welding position of the welding apparatus 100 for each welding area, and gives control coordinates according to the welding position.

On the other hand, although the welding area is classified according to the set values of the welding parameters, all the welding operations can not be performed in one position due to the limit of the operable area of the welding device 100 even in one welding area. For example, when the welding apparatus 100 is at the position M, it is assumed that the workable area is the same as the area indicated by the reference symbol sw. In this case, the control unit 350 divides the region d into a plurality of welding regions for dividing the region d in step S220. In step S230, the control unit 350 determines the welding positions for the respective welding regions. In accordance with the welding position determined in step S240, Coordinates can be assigned.

Next, the control unit 350 of the management server 300 sets the coordinates, the welding position, and the welding parameter setting values including the position coordinates and the control coordinates for the welding region or the welding region respectively in the welding apparatus 100 and To the management device (200). For convenience of explanation, the coordinates, the welding position, and the welding parameter set values including the position coordinates and the control coordinates with respect to each of the welding region or the welding portion region will be referred to as welding information.

The welding apparatus 100 that has received the welding information performs welding in accordance with the welding information in step S260, and performs welding recording. This step S260 is the same as that described in steps S140 through S170 of FIG. When the welding is completed, the welding apparatus 100 may transmit the welding record to the management device 200 and the management server 300 in step S270. Here, the welding record includes a measurement value corresponding to the set value of the welding parameter.

Then, the control unit 350 of the management server 300 may store the welding record in the storage unit 330. In particular, if there is a user's request at step S280, the control unit 350 of the management server 300 may display the welding record through the display unit 340. [ 9 or 10, when displaying the welding record, the control unit 350 first displays a figure divided by the welding area, and for example, If you select a specific weld zone, such as 10, you can display the weld record for that weld zone. Here, the welding record includes the set values for the welding parameters and the corresponding measured values. In addition, the welding record includes the coordinates and the measured value of the position where the welding defect occurred when the welding defect is detected at the time of welding. Here, the coordinates may be at least one of position coordinates and control coordinates.

The welding method according to an embodiment of the present invention can be implemented in a form of a program readable by various computer means and recorded on a computer-readable recording medium. Here, the recording medium may include program commands, data files, data structures, and the like, alone or in combination. Program instructions to be recorded on a recording medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software. For example, the recording medium may be a magnetic medium such as a hard disk, a floppy disk and a magnetic tape, an optical medium such as a CD-ROM or a DVD, a magneto-optical medium such as a floppy disk magneto-optical media) and ROMs, RAMs, flash memory, and the like. Examples of program instructions may include machine language code such as those generated by a compiler, as well as high-level language code that may be executed by a computer using an interpreter or the like. Such a hardware device may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

While the present invention has been described with reference to several preferred embodiments, these embodiments are illustrative and not restrictive. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention and the scope of the appended claims.
