Description

Technical Field

[0001] This invention relates to the field of ship welding technology, and in particular to a welding torch lifting and traversing mechanism and welding system. Background Technology

[0002] When welding T-beams in ships, the welding torch used on the production line is typically raised and lowered using a hydraulically driven rod. However, due to the characteristics of hydraulic piston drive, vibration occurs at the end of the welding stroke, i.e., each time welding stops. This causes circumferential displacement between the torch holder connector and the connecting rod, leading to deviations in the welding angle during subsequent welding processes, resulting in lower weld accuracy and quality. Furthermore, the space currently available for fixing the hydraulic drive components of the welding torch is too confined, hindering maintenance. Therefore, ensuring that the welding torch stops vibrating and its position remains unchanged upon welding termination, while also making efficient use of space for easy maintenance by operators, is a problem that needs to be solved by those in the field. Summary of the Invention

[0003] The purpose of this invention is to provide a welding torch lifting and traversing mechanism and welding system to ensure that the welding torch no longer vibrates when welding is terminated and its position no longer changes, while making reasonable use of space to facilitate maintenance by operators.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] The welding torch lifting and traversing mechanism includes:

[0006] Mounting base, drive equipment and transmission device fixed on the mounting base, the transmission device includes a transmission screw, lifting assembly, lateral movement assembly and fixing assembly arranged in a one-to-one correspondence, at least two of the transmission screws are arranged on the mounting base along a first direction, the lifting assembly is screwed to the outside of the transmission screw and connected to the lateral movement assembly, and the fixing assembly is arranged on the lateral movement assembly for fixing the welding torch.

[0007] When the drive device drives the transmission screw to rotate, the lifting component can drive the lateral component, the fixing component and the welding torch to move synchronously along the first direction, and the fixing component can move along the second direction under the drive of the lateral component. The first direction and the second direction are perpendicular to each other.

[0008] Optionally, the drive device includes a motor and a transmission system, the transmission system including a driving wheel and a driven wheel, the driving wheel being connected to the motor, the driven wheel meshing with the driving wheel and sleeved on the transmission screw, and the driven wheel and the transmission screw being arranged in a one-to-one correspondence.

[0009] Optionally, the lifting assembly includes a movable nut and a guide sleeve. The movable nut is screwed to the outside of the transmission screw and is fixedly connected to the lateral assembly. The guide sleeve is fixed in the mounting base and the movable nut is slidably disposed in the guide sleeve.

[0010] Optionally, the lifting assembly is further provided with an upper limit position and a lower limit position. The upper limit position is located on the outside of the guide sleeve, and the lower limit position is located opposite to the upper limit position along the first direction and is located on the transverse component.

[0011] Optionally, the lateral movement assembly includes a fixed base, a connecting base, a first moving component, and a second moving component. The fixed base is connected to the lifting assembly and the connecting base respectively. The side of the connecting base is connected to the first moving component, and the side of the connecting base away from the lifting assembly is connected to the second moving component. The second moving component is connected to the fixed assembly. The first moving component is capable of moving along the first direction, and the second moving component is capable of moving along the second direction. The transmission screw passes through the fixed base and the connecting base in sequence and is then connected to the second moving component.

[0012] Optionally, a transmission gear is provided at one end of the transmission screw away from the driving device, and a rack is provided on the second moving component. The transmission gear meshes with the rack, and when the transmission screw rotates, the rack moves along the second direction under the drive of the transmission gear. The fixing component is provided on the rack.

[0013] Optionally, the second moving component is provided with a second slide rail and a second slider, the second slider being slidably disposed in the second slide rail along the second direction, and the rack being connected to the second slider.

[0014] Optionally, the first moving component includes a first slider and a first slide rail, the first slider being slidably disposed on the first slide rail along the first direction, and the side of the connecting seat being connected to the first slider.

[0015] Alternatively, the fixing component includes a fixing frame with an adjustable angle and an insulating sleeve in which the welding torch is mounted.

[0016] A welding system, including a welding torch lifting and traversing mechanism, wherein at least two sets of welding torches are installed in the welding torch lifting and traversing mechanism and are arranged facing each other, the welding torch lifting and traversing mechanism can drive the two sets of welding torches to move synchronously along the first direction, and at the same time drive the two sets of welding torches to move in opposite directions or towards each other along the second direction.

[0017] The T-shaped steel is inserted into the lifting and traversing mechanism of the welding torch. The two sets of welding torches are located on both sides of the T-shaped steel and are used to weld the inner side of the T-shaped steel.

[0018] The beneficial effects of this invention are:

[0019] In this invention, the welding torch can move in both the first and second directions through the transmission screw, lifting assembly, and lateral movement assembly in the transmission device. The fixing assembly ensures stable installation of the welding torch, thus replacing hydraulic drive to guarantee stable movement and effectively avoiding torch vibration at the end of each weld. This ensures the welding angle remains accurate, resulting in higher weld accuracy and quality, and improved welding efficiency. Furthermore, the transmission screw and lifting assembly are connected via a screw-nut mechanism, enabling precise control and ensuring smooth transmission. Specifically, at least two transmission screws are provided, effectively utilizing the space on the mounting base to allow two sets of welding torches to operate simultaneously. This improves the overall compactness of the mechanism and facilitates easy handling of the welding torches by operators through lifting and lateral movement. Simultaneously, the transmission device is mounted on the mounting base, has a simple structure, is easy to maintain, and enables automated welding, further improving welding efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] When welding T-beams in ships, the welding torch used on the production line is typically raised and lowered using a hydraulically driven rod. However, due to the characteristics of hydraulic piston drive, vibration occurs at the end of the welding stroke, i.e., each time welding stops. This causes circumferential displacement between the torch holder connector and the connecting rod, leading to deviations in the welding angle during subsequent welding processes, resulting in lower weld accuracy and quality. Furthermore, the space currently available for fixing the hydraulic drive components of the welding torch is too confined, hindering maintenance. Therefore, ensuring that the welding torch stops vibrating and its position remains unchanged upon welding termination, while also making efficient use of space for easy maintenance by operators, is a problem that needs to be solved by those in the field.

[0033] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0034] like Figures 1-2As shown, this embodiment provides a welding torch lifting and traversing mechanism, including a mounting base 100, a driving device 200 fixed on the mounting base 100, and a transmission device. The transmission device includes a transmission screw 10, a lifting component 20, a traversing component, and a fixing component 40, which are arranged in a one-to-one correspondence. At least two transmission screws 10 are arranged on the mounting base 100 along a first direction. The lifting component 20 is screwed to the outside of the transmission screw 10 and connected to the traversing component. The fixing component 40 is arranged on the traversing component and is used to fix the welding torch 300. When the driving device 200 drives the transmission screw 10 to rotate, the lifting component 20 can drive the traversing component, the fixing component 40, and the welding torch 300 to move synchronously along the first direction. The fixing component 40 can move along a second direction under the drive of the traversing component. The first direction and the second direction are perpendicular to each other.

[0035] On the other hand, the welding system includes a welding torch lifting and traversing mechanism, in which at least two sets of welding torches 300 are installed and arranged facing each other. The welding torch lifting and traversing mechanism can drive the two sets of welding torches 300 to move synchronously along a first direction, and at the same time drive the two sets of welding torches 300 to move away from each other or towards each other along a second direction. A T-shaped steel 400 is inserted into the welding torch lifting and traversing mechanism, and the two sets of welding torches 300 are located on both sides of the T-shaped steel 400 respectively, for welding the inner side of the T-shaped steel 400.

[0036] Specifically, in this embodiment, the welding torch 300 can move in the first and second directions through the transmission screw 10, lifting assembly 20, and lateral movement assembly in the transmission device. The fixing assembly 40 ensures stable installation of the welding torch 300, thereby replacing hydraulic drive to guarantee stable movement of the welding torch 300. This effectively avoids the problem of the welding torch 300 shaking at the end of each welding operation, ensuring that the welding angle of the welding torch 300 no longer deviates, resulting in higher weld accuracy and quality, and improved welding efficiency. Furthermore, the transmission screw 10 and the lifting assembly 20 are connected by a screw nut, achieving precise control and ensuring smooth transmission. Specifically, at least two transmission screws 10 are provided, effectively utilizing the space on the mounting base 100 to enable simultaneous operation of two sets of welding torches 300, improving the overall compactness of the mechanism, and facilitating the operator's loading and unloading of the welding torches 300 under the drive of lifting and lateral movement. Simultaneously, the transmission devices are all mounted on the mounting base 100, with a simple structure, easy maintenance, and the ability to achieve automated welding, improving welding efficiency.

[0037] The specific structure of the welding torch lifting and traversing mechanism in this embodiment will be described below.

[0038] like Figure 1As shown, in this embodiment, the welding torch lifting and traversing mechanism includes a mounting base 100, a driving device 200, and a transmission device. Both the driving device 200 and the transmission device are mounted on the mounting base 100, and the welding torch 300 is fixed to the transmission device for welding the T-shaped steel 400. Specifically, in this embodiment, the transmission device includes a transmission screw 10, a lifting assembly 20, a traversing assembly, and a fixing assembly 40, each arranged in a corresponding manner. At least two transmission screws 10 are provided, and correspondingly, at least two lifting assemblies 20, traversing assemblies, and fixing assemblies 40 are also provided, thereby ensuring that multiple welding torches 300 can perform welding operations on the T-shaped steel 400, thus improving welding efficiency. Specifically, in this embodiment, two sets of transmission screws 10, lifting assemblies 20, traversing assemblies, and fixing assemblies 40 are provided.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the height direction of the mounting base 100 is set as the first direction, the length direction of the mounting base 100 is set as the second direction, and the thickness direction of the mounting base 100 is set as the third direction, with each of the three directions being perpendicular to the other. Further, in this embodiment, the transmission screw 10 is mounted on the mounting base 100 along the first direction, the lifting assembly 20 is screwed to the outside of the transmission screw 10 and connected to the transverse component, and the fixing assembly 40 is mounted on the transverse component. This ensures the integrated connection of the lifting assembly 20, the transverse component, and the fixing assembly 40, and synchronous movement is achieved using the screw nut connection between the lifting assembly 20 and the transmission screw 10. Optionally, the welding torch 300 is fixed to the fixing assembly 40. Further, when the driving device 200 drives the transmission screw 10 to rotate, the lifting assembly 20 can drive the transverse component, the fixing assembly 40, and the welding torch 300 to move synchronously along the first direction, allowing the welding torch 300 to move away from or towards the short plate of the T-shaped steel 400 in the first direction. Furthermore, while the lifting assembly 20, the traversing assembly, the fixing assembly 40, and the welding torch 300 move along the first direction, the fixing assembly 40 can move along the second direction under the drive of the traversing assembly, thereby allowing the welding torch 300 to move away from or closer to the long plate of the T-shaped steel 400 in the second direction. Thus, with the cooperation of the transmission screw 10 and the lifting assembly, and driven by the traversing assembly, the reliability of the welding torch 300 installation can be ensured, and the vibration of the welding torch 300 during the welding process can be effectively avoided, making the movement of the welding torch 300 smoother and improving welding efficiency and quality.

[0040] Optionally, the mounting base 100 is provided with a first mounting plate 110, a second mounting plate 120, and a third mounting plate 130 arranged parallel from top to bottom along a first direction, and a clearance groove 103 is provided in the middle position of the mounting base 100. Specifically, the drive device 200 is fixed on the first mounting plate 110 to ensure stability. Further, the transmission screw 10 is rotatably disposed in the second mounting plate 120, and the lifting assembly 20 is disposed at the third mounting plate 130 to ensure stable rotation and movement of the transmission screw 10 and the lifting assembly 20. Specifically, a first bearing 101 is provided at the second mounting plate 120, the first bearing 101 is sleeved on the outside of the transmission screw 10 and installed in the second mounting plate 120, thereby ensuring smooth rotation of the transmission screw 10 and avoiding interference between the second mounting plate 120 and the transmission screw 10. For example, in this embodiment, a clearance groove 103 is provided in the middle of the mounting base 100 to separate the two transmission screws 10, and to place the corresponding parts of the transmission device in the transmission device on both sides of the clearance groove 103. This allows the long plate of the T-shaped steel 400 to pass through the clearance groove 103, facilitating assembly line operations and allowing the welding torches 300 on both sides to perform welding operations on the inner side of the T-shaped steel 400. For example, the clearance groove 103 is provided through the third direction to facilitate the smooth movement of the T-shaped steel 400 on the assembly line.

[0041] like Figure 1 As shown, in this embodiment, the driving device 200 includes a motor and a transmission system 210, and the transmission system 210 is provided with a driving wheel 211 and a driven wheel 212. Optionally, in this embodiment, the driving wheel 211 is connected to the output shaft of the motor, the driven wheel 212 meshes with the driving wheel 211, and the driven wheel 212 is sleeved on the outside of the transmission screw 10. Thus, when the motor drives the driving wheel 211 to rotate, under the meshing action of the driving wheel 211 and the driven wheel 212, the transmission screw 10 and the driven wheel 212 rotate synchronously. Further, in this embodiment, the driven wheel 212 and the transmission screw 10 are arranged in a one-to-one correspondence, that is, there are also two driven wheels 212, and the two driven wheels 212 are respectively located on opposite sides of the driving wheel 211. For example, the driving wheel 211 is also located in the middle of the mounting base 100 and corresponds to the clearance groove 103, and is located above the clearance groove 103. Thus, the two driven wheels 212 are symmetrically arranged with respect to the clearance groove 103, thereby making the two transmission screws 10 and their corresponding transmission devices symmetrically arranged with respect to the clearance groove 103. The two sets of welding torches 300 can also be symmetrically arranged with respect to the long plate of the T-shaped steel 400, thereby realizing synchronous movement in the first direction and the second direction, and keeping the distance between the two sets of welding torches 300 and the T-shaped steel 400 the same, ensuring welding quality.

[0042] like Figure 1As shown, in this embodiment, the lifting assembly 20 includes a movable nut 21 and a guide sleeve 22. The movable nut 21 is screwed to the outside of the transmission screw 10, and when the transmission screw 10 rotates, the movable nut 21 can move linearly along its axis on the transmission screw 10, thus forming a transmission structure for the screw nut. Optionally, in this embodiment, both transmission screws 10 are arranged along the first direction, and the movable nut 21 is fixedly connected to the transverse component, thereby the movable nut 21 can drive the transverse component to move along the first direction on the transmission screw 10. Further, the guide sleeve 22 is fixed in the third mounting plate 130 of the mounting base 100, and the movable nut 21 is slidably disposed in the guide sleeve 22, thereby guiding the movable nut 21 through the guide sleeve 22 and avoiding motion interference between the movable nut 21 and the mounting base 100.

[0043] Combination Figure 1 and Figure 2 As shown, exemplarily, the lifting assembly 20 is further provided with an upper limit position 201 and a lower limit position 202. Optionally, the upper limit position 201 is located on the outside of the guide sleeve 22, and the lower limit position 202 is located opposite to the upper limit position 201 along a first direction. The lower limit position 202 is located on the transverse moving assembly, thus the position of the upper limit position 201 is fixed, and the lower limit position 202 can move in the first direction with the transverse moving assembly under the drive of the moving nut 21 to move closer to or away from the upper limit position 201, thereby limiting the movement range of the moving nut 21. Exemplarily, sensors are provided on the upper limit position 201 and the lower limit position 202 to record their relative position and distance. The specific method can be set as needed, and will not be described in detail here.

[0044] Combination Figure 1 and Figure 2 As shown, in this embodiment, the lateral movement assembly includes a fixed base 31, a connecting base 32, a first moving component 33, and a second moving component 34. Optionally, the fixed base 31 is connected to the moving nut 21 and the connecting base 32 in the lifting assembly 20, respectively. The side of the connecting base 32 is connected to the first moving component 33, and the side of the connecting base 32 away from the lifting assembly 20 is connected to the second moving component 34. The second moving component 34 is connected to the fixed assembly 40. Specifically, in this embodiment, the first moving component 33 can move along a first direction, and the second moving component 34 can move along a second direction, thereby ensuring the stability of the welding torch 300 moving along the first direction and enabling it to move along the second direction. Further, the transmission screw 10 passes through the fixed base 31 and the connecting base 32 in sequence and is connected to the second moving component 34. When the transmission screw 10 rotates, it can drive the second moving component 34 to move along the second direction, providing it with a power source.

[0045] Specifically, the fixed base 31 is provided with a connecting cylinder 311 and a fastening assembly 312, and a second bearing 102 is provided between the fixed base 31 and the transmission screw 10. Optionally, the connecting cylinder 311 is located at the top of the fixed base 31 and is connected to the movable nut 21 through the fastening assembly 312, thereby ensuring a stable connection between the fixed base 31 and the movable nut 21. Exemplarily, the fastening assembly 312 includes studs and nuts and is provided in four sets, thereby fixing the connecting cylinder 311 and the movable nut 21 together through the nuts and studs. Further, the transmission screw 10 passes through the connecting cylinder 311, and there is an annular gap between the two to avoid interference with the rotation of the transmission screw 10. Optionally, the connecting cylinder 311 is inserted into the seat of the fixed base 31, and the transmission screw 10 passes through the connecting cylinder 311 and then through the seat. The transmission screw 10 is fitted with a second bearing 102, which is installed in the seat, thereby ensuring the rotation of the transmission screw 10 in the fixed base 31.

[0046] Furthermore, the connecting seat 32 is configured with an L-shaped structure, and a clearance hole is provided on the connecting seat 32. The transmission screw 10 passes through the clearance hole and is connected to the second moving component 34. For example, the gap between the clearance hole and the transmission screw 10 is greater than the gap between the connecting cylinder 311 and the transmission screw 10 to ensure smooth rotation of the transmission screw 10. Optionally, the first moving component 33 includes a first slider 331 and a first slide rail 332. Specifically, the first slide rail 332 extends along a first direction and is disposed on the mounting base 100, located below the third mounting plate 130. Furthermore, the first slider 331 is slidably mounted on the first slide rail 332 along the first direction, and the side of the connecting seat 32 is connected to the first slider 331. Thus, when the movable nut 21 moves along the first direction, the first slider 331 moves synchronously along the first slide rail 332 along the first direction. This provides stable support for the connecting seat 32 while ensuring stable movement of the lateral component along the first direction. The L-shaped structure of the connecting seat 32 also increases the contact area between the connecting seat 32 and the first slider 331, resulting in higher mechanical strength. Accordingly, the structure and number of the first slider 331 and the first slide rail 332 can be configured as needed.

[0047] like Figure 2As shown, the second moving component 34 includes a second slide rail 341, a second slider 342, and a rack 343. Specifically, the second slide rail 341 has a closed side and an open side. The closed side is fixed to the bottom of the connecting seat 32, and the second slider 342 is slidably disposed on the open side. Specifically, the second slider 342 is slidably disposed in the second slide rail 341 along a second direction. The rack 343 is connected to the second slider 342, and the fixing component 40 is connected to the side of the rack 343 opposite to the second slider 342. Exemplarily, the second slide rail 341 is provided with an I-shaped groove, and the second slider 342 is configured as an I-shaped block, thereby enabling the second slider 342 to be confined within the second slide rail 341, thus ensuring that the second slider 342 will not fall off during sliding.

[0048] Furthermore, a transmission gear 11 is provided at the end of the transmission screw 10 opposite to the drive device 200. The transmission gear 11 meshes with a rack 343, so that when the transmission screw 10 rotates, the rack 343 moves along the second direction under the drive of the transmission gear 11, thereby realizing the movement of the welding torch 300 on the fixed assembly 40 in the second direction. Specifically, two racks 343 are provided, and the two racks 343 are located on both sides of the transmission gear 11 along the third direction. Figure 1 As shown, by way of example, two fixing components 40 are respectively connected to a rack 343 on the front side of the two transmission screws 10 and a rack 343 on the rear side of the two transmission screws 10. That is, one fixing component 40 is located on the front side of the two transmission screws 10 and the other is located on the rear side of the two transmission screws 10. Thus, when the two transmission screws 10 rotate, the two fixing components 40 can be driven to move relative to or away from each other in the second direction, thereby realizing that the two sets of welding torches 300 simultaneously approach or move away from the T-shaped steel 400.

[0049] like Figure 1 and Figure 2As shown, in this embodiment, the fixing component 40 includes a fixing shaft 41, a locking sleeve 42, a fixing frame 43, an insulating sleeve 44, and a connecting post 45. Optionally, one end of the fixing shaft 41 is connected to the rack 343, and the other end is connected to the fixing frame 43, with the welding torch 300 disposed in the fixing frame 43. Exemplarily, the connecting post 45 passes through the bottom end of the fixing shaft 41 and the locking sleeve 42 along a third direction, and the locking sleeve 42 is connected to the fixing frame 43, thereby ensuring a stable connection of the fixing frame 43. Optionally, the connecting post 45 is configured as a polygonal prism, and the locking sleeve 42 is provided with a polygonal through hole corresponding to the connecting post 45, allowing the connecting post 45 to pass through and be confined within the locking sleeve 42. Exemplarily, the connecting post 45 is a hexagonal prism, and the locking sleeve 42 is provided with hexagonal holes, with the hexagonal prism and the hexagonal holes corresponding one-to-one. Furthermore, the angle of the fixing frame 43 can be adjusted by changing the relative angle between the fixing frame 43 and the connecting column 45, or the relative angle between the connecting column 45 and the locking sleeve 42. Specifically, an insulating sleeve 44 is provided on the fixing frame 43, and the welding torch 300 passes through and is installed in the insulating sleeve 44 to ensure the stability of the welding torch 300. The welding angle of the welding torch 300 can be adjusted by adjusting the angle of the fixing frame 43, thereby improving welding efficiency and quality.

[0050] like Figure 2 As shown, exemplarily, two locking sleeves 42 are provided, located on both sides of the fixed shaft 41 respectively. Both locking sleeves 42 are sleeved on the outside of the connecting post 45, thereby enabling the two welding torches 300 to be arranged side by side along a third direction. This allows the rotation of a single transmission screw 10 to drive the two welding torches 300 to move synchronously. By adjusting the distance between the two welding torches 300 along a third direction, two T-shaped steels 400 can be welded simultaneously, improving welding efficiency. Furthermore, by adjusting the size and number of locking sleeves 42 and connecting posts 45, multiple T-shaped steels 400 can be operated simultaneously, improving the efficiency of the production line.

[0051] The specific structure of the welding system in this embodiment will be described below.

[0052] Optionally, the welding system includes the aforementioned welding torch lifting and traversing mechanism, and at least two sets of welding torches 300 are installed in the welding torch lifting and traversing mechanism, with the two sets of welding torches 300 facing each other. Driven by the welding torch lifting and traversing mechanism, the two sets of welding torches 300 can move synchronously along a first direction simultaneously, and simultaneously move away from or towards each other along a second direction. Specifically, the T-shaped steel 400 is inserted into the welding torch lifting and traversing mechanism, and the two sets of welding torches 300 are located on opposite sides of the T-shaped steel 400. Driven by the welding torch lifting and traversing mechanism, the two sets of welding torches 300 can simultaneously approach or move away from the T-shaped steel 400 to weld the inner side of the T-shaped steel 400, and smoothly leave after welding, avoiding vibration and ensuring welding quality while improving welding efficiency.

[0053] Thus, the lifting assembly 20 can move up and down in the first direction and the lateral assembly can move synchronously in the second direction simply by rotating the transmission screw 10. By utilizing the high-precision transmission method of the screw and nut and the stable connection of the gear and rack, the problem of the welding torch 300 shaking when each welding is terminated can be effectively avoided, ensuring the smoothness of the transmission. This ensures that the welding angle of the welding torch 300 no longer deviates, resulting in higher accuracy and quality of the weld and improved welding efficiency.
