Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of welding, and in particular relates to welding equipment and a processing production line. Background Art
[0002] Welding, also known as fusion welding, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Welding achieves the purpose of joining through the following three ways: The first is fusion welding, which heats the workpieces to be joined to partially melt them to form a molten pool. The molten pool is cooled and solidified before joining. If necessary, molten fillers can be added to assist. It is suitable for welding various metals and alloys without pressure. The second is pressure welding. Pressure must be applied to the weldment during the welding process. It belongs to the processing of various metal materials and partial metal materials. The third is brazing, which uses a metal material with a lower melting point than the parent material as a brazing material, uses liquid brazing material to wet the parent material, fill the joint gap, and diffuse with the parent material to achieve a connection between the welded parts. It is suitable for welding various materials, and also suitable for welding different metals or heterogeneous materials.
[0003] At present, when welding steel plates, most companies align and splice two plates manually, and then press the plates manually to prevent them from shifting during welding. After pressing the plates, the two plates are welded together by the welding machine head.
[0004] The existing welding method has the following shortcomings:
[0005] Manually pressing down the plate and then using the welding machine head for welding not only increases the workers' workload, but also creates greater risks during welding, which can easily lead to work-related injuries. Summary of the invention
[0006] In view of this, the present invention provides a welding device and a processing production line to solve the problem in the prior art that the plate is manually pressed and then welded using a welding head, which not only increases the work intensity of the workers, but also poses a greater risk during welding and is prone to causing work-related injuries.
[0007] The technical solution adopted by the present invention is as follows:
[0008] A welding device comprises a guide rail and a welding machine head located above the guide rail, wherein two placing tables are slidably connected to the guide rail, and the two placing tables are driven by a driving device to move on the guide rail; each of the placing tables is provided with an air storage box, one end of the air storage box is connected to an air pipe, and the end of the air pipe away from the air storage box is connected to an air nozzle, and the air outlet of the air nozzle faces the table surface of the placing table; each of the placing tables is also slidably connected to an abutment plate, and the abutment plate is transmission-connected to the air storage box through a transmission device, and when the abutment plate moves toward the direction close to the air storage box, the gas in the air storage box is compressed by the transmission device, so that the gas is ejected from the air nozzle.
[0009] In this technical solution, it should be noted that the welding machine head is a prior art and can be used to weld steel plates. There are two guide rails, which are arranged in parallel and at intervals. The gas storage box has an inflation port (not shown in the figure), and gas is injected into the gas storage box through the inflation port. A one-way valve (not shown in the figure) is arranged at the connection between the air pipe and the gas storage box. When the gas in the gas storage box goes out of the air pipe, the one-way valve is opened; the driving device can drive the two placement tables to move closer to each other or away from each other; the abutment plate is used to abut the plates to be welded; in this solution, when it is necessary to fix the two plates for welding, the two plates are placed on the top of the placement tables respectively, and one end of the plate is in contact with the abutment plate. At this time, the two plates are in a separated state, and then the two placement tables are driven by the driving device to gradually move closer, so that the two plates gradually move closer. When the ends of the two plates are in contact, the driving device continues to start, and the two placement tables continue to move closer. In this process, the two plates give each other thrust and thrust. The air in the air tank is compressed by the transmission device and ejected from the air nozzle to act on the plate, thereby blowing away the dust on the plate and ensuring the quality of welding. Finally, when the two plates are pressed against each other, that is, the two abutment plates clamp the two plates together, the driving device is closed, and the two plates can be welded at this time. In summary, in the present invention, the driving device is set up to drive the two placing tables to automatically move closer to each other, so that the two plates on the two placing tables can be gradually clamped and fixed by the two abutment plates, without manual fixation of the plates, reducing the work intensity of the staff and improving safety. Secondly, in the process of the two plates being clamped and fixed, the gas in the air tank is automatically ejected from the air nozzle through the transmission device and acts on the plate, so as to blow away the dust on the plate and ensure the quality of welding of the two plates.
[0010] Preferably, the transmission device includes a piston and a piston rod, the piston is slidably embedded in the air storage box, one end of the piston rod is connected to the piston, and the other end passes through the outside of the air storage box and is connected to the abutment plate, and the connection point between the air pipe and the air storage box is located on the side of the piston away from the abutment plate.
[0011] In this technical solution, it should be noted that the transmission device specifically includes a piston and a piston rod. The number of the piston rods is specifically two, and the two piston rods are symmetrically arranged. In this solution, when the abutment plate moves toward the air storage box, the abutment plate drives the piston in the air storage box to move through the piston rod, thereby compressing the air in the air storage box, so that the air in the air storage box passes through the air pipe and is ejected from the air nozzle to blow away the dust on the surface of the plate.
[0012] Preferably, a spring is sleeved on the piston rod, one end of the spring is connected to the outer shell of the air storage box, and the other end of the spring is connected to the abutment plate.
[0013] In this technical solution, it should be noted that if no spring is provided, then in order for the two plates to be clamped and fixed by the two abutment plates, the abutment plates must be in complete contact with the gas box, that is, the two plates can only be fixed after the abutment plates cannot be completely moved. Secondly, when the abutment plates are in contact with the gas box, the abutment plates are immediately blocked by the gas box. At this time, the clamping force exerted on the two plates will suddenly increase. If the driving device is not closed in a short time, the two plates may be damaged due to excessive force. Based on the above problems, the present application is provided with a spring, and the spring has supporting and buffering effects. The spring is provided so that the abutment plate can compress the spring during the movement. After the spring is compressed, it can give pressure to the abutment plate toward the plate. During the gradual compression of the spring, the clamping force of the abutment plate on the plate will gradually increase, rather than increase instantaneously, thereby reducing the probability of damage to the plate due to instantaneous excessive force.
[0014] Preferably, the air pipe includes a parallel pipe section parallel to the placement table, the parallel pipe section is a telescopic structure, and the air nozzle is located outside the placement table.
[0015] In this technical solution, it should be noted that the specific telescopic structure of the parallel pipe segments can be a two-section pipe body structure, that is, one pipe body is slidably inserted into another pipe body to realize the telescopic function; by setting up parallel pipe segments with a telescopic structure, the position of the air nozzle in the length direction of the guide rail can be adjusted, that is, the staff can adjust the air nozzle to the vicinity of the contact position of the two plates in advance, so that most of the gas ejected from the air nozzle can act on the contact position (welding position) between the two plates.
[0016] Preferably, a vacuum cleaner is provided on the air storage box, and the suction end of the vacuum cleaner faces the placement table.
[0017] In this technical solution, it should be noted that, by cooperating with the vacuum cleaner and the air nozzle, the air nozzle blows up the dust on the surface of the plate, and the vacuum cleaner sucks in the blown-up dust, so that the dust removal efficiency is higher.
[0018] Preferably, a support plate is fixedly provided in the middle of the guide rail, and the driving device includes a rotating plate and a cylinder. The rotating plate is arranged at an angle, and a fixed shaft is rotatably connected to the middle of the rotating plate, and the fixed shaft is connected to the support plate. Transmission rods are hinged at both ends of the rotating plate, and each transmission rod is hinged to the corresponding placement table at one end away from the rotating plate; the cylinder is fixed at the bottom of one of the placement tables, and the cylinder is arranged parallel to the guide rail, and the output end of the cylinder is fixedly connected to the support plate.
[0019] In this technical solution, it should be noted that when it is necessary to drive the two placement tables closer to each other to clamp the two plates, the cylinder is started, and the output end of the cylinder contracts, driving the placement table connected to the cylinder along the guide rail to move closer to the other placement table. During the movement of the placement table, the other placement table is synchronously moved closer through the transmission of the transmission rod and the rotating plate until the two plates on the two placement tables are clamped and fixed by the abutment plates.
[0020] Preferably, a mounting groove is provided at the end of each of the placement tables, a vertical axis is rotatably connected in the mounting groove, and the end of the transmission rod away from the rotating plate is hinged to the placement table through the vertical axis; an extension plate is also provided at the end of each of the placement tables, and the extension plate is a retractable structure, and the extension plate can slide along the height direction of the placement table, the top of the extension plate is flush with the top of the placement table, and a positioning plate is provided at the end of the extension plate away from the placement table, and the height of the positioning plate is higher than the height of the extension plate; a linkage device is provided at the bottom of the extension plate, and the linkage device connects the positioning plate with the vertical axis, and when the vertical axis rotates forward or reversely, the linkage device can drive the extension plate to descend or rise. The linkage device includes a linkage rod provided at the bottom of the extension plate, one end of the linkage rod extends into the mounting groove and is threadedly connected to the vertical axis, and when the vertical axis rotates forward or reversely, the linkage rod can be driven to descend or rise.
[0021] In this technical solution, it should be noted that since the staff manually places the plates on the placement table, the plates placed on the placement table may be placed crookedly, resulting in deviation from the positions where the two plates need to be welded after being clamped and fixed. Based on this, the present invention is provided with an extension plate and a positioning plate. The extension plate is a retractable structure, including a first plate body and a second plate body. The positioning plate is arranged on the second plate body, a retractable shaft is fixed on the second plate body, the retractable shaft is slidably inserted into the first plate body, and an elastic member is sleeved on the retractable shaft. Through the above arrangement, the extension plate can be retracted, the positioning plate is parallel to the abutment plate, the staff can insert the plate between the positioning plate and the abutment plate, and the abutment plate and the positioning plate cooperate to position and fix the plate. The plates placed on the placement table will not be skewed; further, since the ends of the two plates need to be in contact before welding can be carried out, and the positioning plate set will hinder the contact of the ends of the two plates, based on this, a linkage device is also provided in the present scheme. When the vertical shaft rotates forward (that is, the process of the two placement tables approaching each other), the linkage rod threadedly connected to the vertical shaft moves downward through the threaded structure, driving the extension plate and the positioning plate to move downward, so that before the ends of the two plates are in contact, the top of the positioning plate moves to a position flush with or below the top of the placement table, that is, at this time, the positioning plate will not hinder the contact of the two plates, and when the two plates are in contact, the two extension plates are adapted to the change in the distance between the two plates through the telescopic structure set. In summary, the present invention can achieve the placement specification of the plates through the positioning plate set, and the plates are placed skewed when placed. Secondly, the present invention can form a linkage with the main shaft through the linkage device set, and use the rotation of the main shaft as the driving force to drive the extension plate and the positioning plate to descend or rise, so as to prevent the positioning plate from hindering the contact of the two plates.
[0022] Preferably, a pressure sensor is provided at the end of the abutment plate, the pressure sensor is electrically connected to an external controller, the controller is electrically connected to the cylinder, and when the pressure sensed by the pressure sensor reaches a set threshold, the controller controls the cylinder to close.
[0023] In this technical solution, it should be noted that a pressure sensor is provided to sense the pressure applied to the plate during the clamping process. When the pressure applied to the plate reaches a set threshold, it indicates that the plate has been fixed. At this time, the controller controls the cylinder to close and welding can be carried out.
[0024] Preferably, the welding head can be displaced along the width direction of the guide rail through a lateral displacement device, the welding head can be raised or lowered through a lifting device, and the welding head can be moved along the length direction of the guide rail through a longitudinal displacement device, wherein the lateral displacement device includes a first frame, the first frame is located above the placement table, and a first screw is rotatably connected to the first frame, the first screw is driven by a first motor, a first slide rail is fixed to the first frame, a first slide seat is slidably connected to the first slide rail, the first slide seat is threadedly connected to the first screw, the lifting device is installed on the first slide seat, the welding head is installed on the lifting device, and the lifting device includes a vertically arranged The second lead screw is rotatably connected to the first slide, the second lead screw is driven by the second motor, a second slide rail is vertically provided on the first slide, the second slide rail is slidably connected to the second slide, the second slide is threadedly connected to the second lead screw, and the welding head is fixed on the second slide; the longitudinal displacement device includes a third frame, there are two third frames, which are located on both sides of the guide rail and are parallel to the guide rail, the third frame is rotatably connected to the third lead screw, the third lead screw is driven by the third motor, a third slide rail is provided on the third frame, the third slide rail is slidably connected to the third slide, the third slide is threadedly connected to the third lead screw, and the first frame is installed on the third slide.
[0025] In this technical solution, after the two plates are clamped and fixed, the third motor is started, and the third motor drives the third lead screw to rotate, so that the third slide moves along the length direction of the guide rail to move the welding head to the contact gap between the two plates, and then the second motor is started, and the second motor drives the second lead screw to rotate, and the rotation of the second lead screw drives the second slide to move downward, so that the welding port of the welding head drops and contacts the position where welding is required between the two plates, and finally the first motor and the welding head are started, and the first motor drives the first lead screw to rotate, drives the first slide and the welding head to move along the width direction of the track, and the welding head welds the two plates at the same time; in summary, in the present invention, through the provision of a lateral displacement device, a longitudinal displacement device and a lifting device, the welding head can be driven to move to any position, so as to realize the automatic welding operation of the welding head and improve the degree of automation of welding.
[0026] A welding production line includes a welding device.
[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0028] 1. In the present invention, the driving device can drive the two placement tables to automatically approach each other, so that the two plates on the two placement tables can be gradually clamped and fixed by the two clamping plates, without manual fixation of the plates, reducing the work intensity of the staff and improving safety.

[0029] 2. In the present invention, a spring is provided. The spring has supporting and buffering functions.

During the gradual compression of the spring, the clamping force of the abutment plate on the plate will gradually increase (the gradual increase process is convenient for controlling the closing of the driving device), rather than increasing instantly, thereby reducing the probability of damage to the plate due to excessive instantaneous force;
[0030] 3. In the present invention, the positioning plate can be arranged to achieve the placement specification of the plate, and the plate is placed crookedly. Secondly, the linkage device arranged in the present invention can form a linkage with the main shaft, and the rotation of the main shaft is used as the driving force to drive the extension plate and the positioning plate to descend or rise, so as to prevent the positioning plate from hindering the contact between the two plates;
[0031] 4. In the present invention, a pressure sensor is provided to sense the pressure on the plate during the clamping process.

[0053] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other. Embodiment 1
[0054] like Figure 1-Figure 13As shown, a welding device is disclosed in an embodiment of the present invention, including a guide rail 5 and a welding head 1 located above the guide rail 5, wherein two placement tables 6 are slidably connected to the guide rail 5, and the two placement tables 6 are driven by a driving device to move on the guide rail 5; each of the placement tables 6 is provided with an air storage box 9, one end of the air storage box 9 is connected to an air pipe 10, and the end of the air pipe 10 away from the air storage box 9 is connected to an air nozzle 102, and the air outlet of the air nozzle 102 faces the surface of the placement table 6; each of the placement tables 6 is also slidably connected to an abutment plate 8, and the abutment plate 8 is transmission-connected to the air storage box 9 through a transmission device. When the abutment plate 8 moves toward the direction close to the air storage box 9, the gas in the air storage box 9 is compressed by the transmission device, so that the gas is ejected from the air nozzle 102. It should be noted that the welding machine head 1 is a prior art and can be used to weld steel plates 7. There are two guide rails 5, which are arranged in parallel and at intervals. The gas storage box 9 has an air filling port (not shown in the figure), and gas is injected into the gas storage box 9 through the air filling port. A one-way valve (not shown in the figure) is arranged at the connection between the air pipe 10 and the gas storage box 9. When the gas in the gas storage box 9 goes out of the air pipe 10, the one-way valve is opened; the driving device can drive the two placement tables 6 to move closer to each other or away from each other; the abutment plate 8 is used to abut the plates 7 to be welded; in this solution, when it is necessary to fix the two plates 7 for welding, the two plates 7 are respectively placed on the top of the placement table 6, and one end of the plate 7 is in contact with the abutment plate 8. At this time, the two plates 7 are in a separated state, and then the two plates 7 are driven The driving device drives the two placement tables 6 to gradually move closer, and then the two plates 7 are gradually moved closer. When the ends of the two plates 7 are in contact, the driving device continues to start, and the two placement tables 6 continue to move closer. In this process, the two plates 7 give each other thrust and transmit the thrust to the abutment plate 8, so that the abutment plate 8 moves toward the direction close to the air storage box 9. In the process of the movement of the abutment plate 8, the gas in the air storage box 9 is compressed by the transmission device, so that the gas is ejected from the air nozzle 102. The ejected gas acts on the plate 7, and then the dust on the plate 7 can be blown away to ensure the quality of welding. Finally, when the two plates 7 are pressed against each other, that is, the two abutment plates 8 clamp the two plates 7 and fix them, the driving device is turned off, and the two plates 7 can be welded at this time. Embodiment 2
[0055] like Figure 3 , Figure 4 , Figure 5As shown, this embodiment is substantially the same as the above embodiment, except that the transmission device includes a piston 84 and a piston rod 82, the piston 84 is slidably embedded in the air storage box 9, one end of the piston rod 82 is connected to the piston 84, and the other end passes through the outside of the air storage box 9 and is connected to the abutment plate 8, and the connection between the air pipe 10 and the air storage box 9 is located on the side of the piston 84 away from the abutment plate 8. It should be noted that the transmission device specifically includes a piston 84 and a piston rod 82, and the number of the piston rods 82 is specifically two, and the two piston rods 82 are symmetrically arranged. In this solution, when the abutment plate 8 moves toward the direction of approaching the air storage box 9, the abutment plate 8 drives the piston 84 in the air storage box 9 to move through the piston rod 82, thereby compressing the air in the air storage box 9, so that the air in the air storage box 9 passes through the air pipe 10 and is ejected by the air nozzle to blow away the dust on the surface of the plate 7.
[0056] like Figure 5 As shown, in this embodiment, a spring 83 is sleeved on the piston rod 82 , one end of the spring 83 is connected to the outer shell of the air storage box 9 , and the other end is connected to the abutment plate 8 . It should be noted that if the spring 83 is not provided, then in order for the two plates 7 to be clamped and fixed by the two abutment plates 8, the abutment plates 8 must be in full contact with the air box 9, that is, the two plates 7 can only be fixed after the abutment plates 8 cannot be completely moved. Secondly, when the abutment plates 8 are in contact with the air box 9, the abutment plates 8 are immediately blocked by the air box 9. At this time, the clamping force on the two plates 7 will suddenly increase. If the driving device is not closed in a short time, the two plates 7 may be damaged due to excessive force. Based on the above problems, the present application is provided with a spring 83, which has a supporting and buffering effect. The spring 83 is provided so that the abutment plate 8 can compress the spring 83 during the movement. After compression, the spring 83 can give the abutment plate 8 pressure toward the plate 7. During the gradual compression of the spring 83, the clamping force of the abutment plate on the plate 7 will gradually increase, rather than increase instantaneously, thereby reducing the probability of damage to the plate 7 due to excessive instantaneous force.

It should be noted that the specific telescopic structure of the parallel pipe section 101 can be a two-section pipe body structure, that is, one pipe body is slidably inserted into the other pipe body to achieve the telescopic function; by setting the parallel pipe section 101 with a telescopic structure, the position of the air nozzle 102 in the length direction of the guide rail 5 can be adjusted, that is, the staff can adjust the air nozzle 102 to the vicinity of the contact position of the two plates 7 in advance, so that most of the gas ejected from the air nozzle 102 can act on the contact position (welding position) between the two plates 7.
[0058] like Figure 3 As shown, in this embodiment, a vacuum cleaner 103 is provided on the air storage box 9, and the suction end of the vacuum cleaner 103 faces the placement table 6. It should be noted that the vacuum cleaner 103 cooperates with the air nozzle 102, the air nozzle 102 blows up the dust on the surface of the plate 7, and the vacuum cleaner 103 sucks in the blown dust, so that the dust removal efficiency is higher.

The linkage device includes a linkage rod 18 disposed at the bottom of the extension plate 11. One end of the linkage rod 18 extends into the installation groove 16 and is threadedly connected to the vertical shaft 17. When the vertical shaft 17 rotates forward or reversely, it can drive the linkage rod 18 to descend or ascend. It should be noted that, since the staff manually places the plate 7 on the placement table 6, the plate 7 placed on the placement table 6 may be placed crookedly, resulting in deviation from the position where the two plates 7 need to be welded after being clamped and fixed. Based on this, the present invention is provided with an extension plate 11 and a positioning plate 113. The extension plate 11 is a retractable structure, including a first plate body 111 and a second plate body 112. The positioning plate 113 is arranged on the second plate body 112. A telescopic shaft 114 is fixed on the second plate body 112. The telescopic shaft 114 is slidably inserted into the first plate body 111.

Through the above arrangement, the extension plate 11 can be retracted, and the positioning plate 113 is parallel to the abutment plate 8. The staff can insert the plate 7 between the positioning plate 113 and the abutment plate 8. The abutment plate 8 and the positioning plate 113 The plates 7 are positioned and fixed in cooperation with each other so that the plates 7 placed on the placement table 6 will not be skewed; further, since the ends of the two plates 7 need to be in contact before welding, and the arranged positioning plate 113 will hinder the contact of the ends of the two plates 7, based on this, a linkage device is also provided in the present scheme. When the vertical shaft 17 rotates forward (that is, the process of the two placement tables 6 approaching each other), the linkage rod 18 threadedly connected to the vertical shaft 17 moves downward through the threaded structure, driving the extension plate 11 and the positioning plate 113 to move downward, so that before the ends of the two plates 7 come into contact, the top of the positioning plate 113 moves to a position flush with or below the top of the placement table 6, that is, at this time, the positioning plate 113 will not hinder the contact of the two plates 7, and when the two plates 7 are in contact, the two extension plates 11 are adapted to the change in the distance between the two plates 7 through the arranged telescopic structure.To sum up, the positioning plate 113 provided in the present invention can realize the placement specification of the plate 7, and the plate 7 will not be skewed when placed. Secondly, the linkage device provided in the present invention can form a linkage with the main shaft, and use the rotation of the main shaft as the driving force to drive the extension plate 11 and the positioning plate 113 to descend or rise, so as to prevent the positioning plate 113 from hindering the contact between the two plates 7.

Embodiment 8
[0063] This embodiment is substantially the same as the above embodiment, except that this embodiment provides a welding production line including a welding device.
[0064] The working principle of the present invention is:
[0065] S1. When the two plates 7 need to be fixed for welding, the two plates 7 are respectively inserted between the positioning plate 113 and the abutment plate 8 (the state at this time is as follows). Figure 2 As shown in the figure, the cylinder 161 is started, and the output end of the cylinder 161 contracts, driving the placement table 6 connected to the cylinder 161 to move closer to the other placement table 6 along the guide rail 5. During the movement of the placement table 6, the transmission rod 15 and the rotating plate 14 drive the other placement table 6 to move closer synchronously. During the process of the two placement tables 6 moving closer together, the following actions will occur synchronously:
[0066] First, the transmission rod 15 drives the vertical shaft 17 to rotate forwardly during the rotation process. When the vertical shaft 17 rotates forwardly, the linkage rod 18 threadedly connected to the vertical shaft 17 moves downwardly through the thread structure, driving the extension plate 11 and the positioning plate 113 to move downwardly, so that before the ends of the two plates 7 come into contact, the top of the positioning plate 113 moves to a position flush with or below the top of the placement table 6, that is, at this time, the positioning plate 113 does not hinder the contact between the two plates 7;
[0067] Secondly, the abutment plate 8 moves toward the air storage box 9. During the movement, the abutment plate 8 drives the piston 84 in the air storage box 9 to move through the piston rod 82, thereby compressing the air in the air storage box 9, so that the air in the air storage box 9 passes through the air pipe 10 and is ejected from the air nozzle 102 to blow away the dust on the surface of the plate 7, and at the same time, the dust blown up by the vacuum cleaner 103 is sucked in;
[0068] S2, after the two plates 7 come into contact (the state at this time is as follows Fig.12 As shown in the figure, the pressure sensor 81 on the abutting plate 8 senses the pressure on the plate 7 during the clamping process in real time. When the pressure reaches the set threshold, it indicates that the plate 7 has been fixed. At this time, the controller controls the cylinder 161 to close, and welding can be carried out;
[0069] S3. After the two plates 7 are clamped and fixed, start the third motor 401, and drive the third lead screw 402 to rotate through the third motor 401, so that the third slide 403 moves along the length direction of the guide rail 5 to move the welding head to the contact gap between the two plates 7, and then start the second motor 301, and the second motor 301 drives the second lead screw 302 to rotate, and the rotation of the second lead screw 302 drives the second slide 304 to move downward, so that the welding port of the welding head drops and contacts the position between the two plates 7 that need to be welded, and finally start the first motor 201 and the welding head 1, and the first motor 201 drives the first lead screw 203 to rotate, and drives the first slide 205 and the welding head to move along the width direction of the track, and the welding head welds the two plates 7 at the same time.
