Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, specifically to an automatic welding system and welding method for reinforcing rings. Background Technology

[0002] As core equipment for storing cryogenic media, corrosive media, and high-pressure fluids, LNG tanks for automobiles and chemical tanks directly determine operational safety and service life through their structural strength and sealing performance. To improve the tank's resistance to external pressure instability and reduce the risk of radial deformation, the industry commonly adopts a technical solution of welding reinforcing rings to the outer wall of the tank. Through the rigid connection between the annular reinforcing ring and the tank body, a composite load-bearing structure of the tank body and the reinforcing ring is formed, which can significantly improve the structural stability of the tank under transportation, storage, and operating pressure fluctuations.

[0003] In the existing reinforcing ring welding process, C-shaped steel or steel bars are first made into circular reinforcing rings, which are then fitted onto the tank body at a preset position. After being transported to the welding position, they are pressed and bonded by a clamp. After the reinforcing rings are clamped, since their butt joints are all in the same position, a welding robot sequentially welds the butt joints of the reinforcing rings to initially fix them to the outside of the tank. The welding robot then welds the reinforcing rings to the tank body one by one. The butt joint welding is completed in the first stroke. The tank body does not need to rotate during the butt joint welding to ensure the accuracy of the butt joint position. The welding between the reinforcing rings and the tank body is completed in the second stroke. In this method, the position of the butt joint is accurate and it is easy to program the welding robot. However, the operation is completed in two independent welding strokes. Between the two strokes, robot program switching, welding gun posture adjustment and position calibration are required. In mass production scenarios, the cumulative cycle will significantly reduce the production capacity. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic welding system and method for reinforcing rings to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic welding system for reinforcing rings, comprising:

[0006] The support assembly has an extended first state and a closed second state. In the second state, the support assembly positions and clamps the reinforcing ring so that its butt joint is closed and fits against the outer wall of the tank.

[0007] The drive assembly and the support assembly are connected by a transmission. When the tank is placed on the drive assembly, the transmission assembly drives the support assembly to switch to the second state.

[0008] Preferably, the support assembly includes a frame, a pair of drive shafts, a first bracket, a second bracket, and a floating clamping part. The pair of drive shafts are rotatably connected to the frame. The first bracket is fixedly mounted on the drive shaft, and the second bracket is slidably connected to the drive shaft. The first bracket and the second bracket are connected by the floating clamping part.

[0009] Preferably, the floating clamping part includes a slider, a first elastic element, a rotating shaft, and a floating roller. The slider is slidably connected to the first bracket and the second bracket respectively. The two ends of the rotating shaft are rotatably connected to the two sliders respectively. The first elastic element applies a thrust toward the reinforcing ring to the slider.

[0010] Preferably, it further includes an adaptive removal unit, which includes a first gear, a second gear, a first rotating shaft, a first prism, a third elastic element, a second rotating shaft, a second prism, a fourth elastic element, and a steel brush. A pair of second rotating shafts are respectively rotatably connected to a first bracket and a second bracket. The first gear is fixedly installed at both ends of the rotating shaft. The second gear is fixedly installed on the first rotating shaft. One end of the first prism is fixedly installed on the first rotating shaft. The other end of the first prism is slidably inserted into the second rotating shaft. One end of the second prism is slidably connected into the second rotating shaft. The other end of the second prism is fixedly connected to the steel brush. The third elastic element is sleeved on the first prism, and the fourth elastic element is sleeved on the second prism.

[0011] Preferably, one end of the steel brush extends to the weld seam between the tank body and the reinforcing ring.

[0012] Preferably, the axially extended portion includes a second elastic element, an inclined column, and a guide column. The second elastic element is slidably sleeved on the drive shaft. The second elastic element applies a thrust to the second bracket to move it away from the first bracket. The inclined column and the drive shaft are coaxially fixedly installed. The end of the guide column is rolledly connected to the inclined column.

[0013] Preferably, the drive assembly includes a base, a displacement frame, a fifth elastic element, a bonding roller, an active rack, and a passive gear. The fifth elastic element is disposed between the base and the displacement frame. The bonding roller is rotatably connected to the displacement frame. The active rack is fixedly mounted on the displacement frame. The passive gear meshes with the active rack and is fixedly mounted on the support assembly.

[0014] Preferably, it also includes a servo motor, which drives the bonding roller to rotate, so as to ensure that the tank rotates during welding.

[0015] Preferably, it includes a welding robot, which is mounted on a track that is set along the axial direction of the tank.

[0016] An automatic welding method for reinforcing rings includes the following steps:

[0017] S1, the tank is placed on the drive assembly. After the drive assembly detects that the tank is in place, the drive support assembly switches from the first state to the second state. During this process, the floating clamping part positions and clamps the reinforcing ring, so that the butt joint of the reinforcing ring is closed, and the first elastic element makes it fit tightly against the outer wall of the tank.

[0018] S2, synchronously, when the first and second supports are deployed, the second elastic element pushes the second support away from the first support, so that the reinforcing ring is deployed axially. At the same time, the cooperation of the inclined column and the guide column ensures the stability of the deployment process, so as to ensure that the reinforcing ring can fall smoothly between the first and second supports when the tank is placed.

[0019] S3: The servo motor drives the bonding roller to rotate, causing the tank to rotate on its own axis. At the same time, the welding robot moves along the track to the welding position. During the welding process, the tank continues to rotate to ensure the uniformity of the welding.

[0020] S4, during the rotation of the tank, the steel brush of the adaptive removal section rotates under the drive of the first gear and the second gear to clean the weld seam of the tank and the reinforcing ring. The third elastic element and the fourth elastic element provide buffering and adaptive capabilities respectively, so that the steel brush can adapt to the unevenness of the tank surface and remove oxide layer and impurities.

[0021] S5. After welding is completed, the tank is removed, and the drive assembly drives the support assembly to switch from the second state back to the first state, releasing the clamp on the reinforcing ring.

[0022] S6, Quality Inspection Steps: This step involves using non-destructive testing technology to inspect the weld seam, as well as recording and tracing welding parameters. The parameters and results of each weld are recorded to facilitate quality traceability and process optimization.

[0023] In the above technical solution, the present invention provides an automatic welding system and welding method for reinforcing rings. Through the linkage between the support component and the drive component, the support component can be automatically triggered when the tank is placed, so that it switches from the unfolded state to the clamping state, without the need for manual intervention in the positioning process. The welding method integrates the continuous operation of welding the reinforcing ring to the butt joint and welding the tank circumferential joint, eliminating the program switching and welding gun calibration steps of two independent welding strokes in the prior art, shortening the single welding cycle and improving welding efficiency.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Please see Figure 1-8 An automatic welding system for reinforcing rings provided in this embodiment of the invention includes:

[0036] The supporting component 4 has an extended first state and a closed second state. In the second state, the supporting component 4 positions and clamps the reinforcing ring so that its butt joint is closed and fits against the outer wall of the tank body 2.

[0037] The drive assembly 3 and the support assembly 4 are connected by a transmission. When the tank 2 is placed on the drive assembly 3, the transmission assembly 3 drives the support assembly 4 to switch to the second state.

[0038] Specifically, using the overhead crane in the workshop, when the tank 2 is lifted and placed on the bonding roller 34 of the drive assembly 3, the tank 2's own weight presses the displacement frame 32 downwards. The displacement frame 32 drives the driven gear 36 to rotate through the active rack 35, which in turn drives the transmission shaft 42 of the support assembly 4 to rotate. During the flipping process of the support assembly 4, the support assembly 4 switches from the first unfolded state to the second closed state. During this process, the reinforcing ring placed on the tank 2 is located between the support assemblies 4. After the tank 2 is placed and supported by the bonding roller 34, the support assembly 4 clamps the reinforcing ring, so that the joint of the reinforcing ring is joined together and bonded to the tank 2, achieving the positioning and clamping of the reinforcing ring. The welding robot can achieve welding of the joint of the reinforcing ring and the tank body in one displacement stroke, reducing the calibration between the reinforcing ring and the welding gun and improving welding efficiency.

[0039] In another embodiment of the present invention, please refer to Figure 2 and Figure 3The supporting assembly 4 includes a frame 41, a pair of drive shafts 42, a first bracket 43, a second bracket 44, and a floating clamping part 45. The pair of drive shafts 42 are rotatably connected to the frame 41. The first bracket 43 is fixedly installed on the drive shaft 42. The second bracket 44 is slidably connected to the drive shaft 42. The first bracket 43 and the second bracket 44 are connected by the floating clamping part 45.

[0040] When the tank 2 is placed on the bonding roller 34 of the drive assembly 3, the weight of the tank 2 presses the displacement frame 32 downward. The displacement frame 32 drives the driven gear 36 to rotate via the active rack 35, thereby driving the transmission shaft 42 to rotate. Since the first bracket 43 is fixedly connected to the transmission shaft 42, the first bracket 43 will rotate synchronously with the transmission shaft 42. Although the second bracket 44 is slidably connected to the transmission shaft 42, it rotates synchronously with the first bracket 43 due to the restriction of the floating clamping part 45. Finally, the supporting assembly 4 switches from the unfolded first state to the closed second state. Simultaneously, the floating clamping part 45 not only serves to connect the first support 43 and the second support 44, but also, through the floating roller 454 of the floating clamping part 45, first contacts the outer circle of the reinforcing ring and achieves flexible clamping of the reinforcing ring. In this way, when the tank body 2 rotates, the reinforcing ring will rotate with the tank body 2 under the action of friction, so as to ensure that the position of the reinforcing ring butt joint relative to the tank body 2 is always in the initial position during the rotation of the tank body 2. In this way, during the welding process of the reinforcing ring in sequence, the position of the reinforcing ring butt joint is determined, ensuring that the welding robot 1 can be positioned and welded smoothly.

[0041] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The floating clamping part 45 includes a slider 451, a first elastic element 452, a rotating shaft 453, and a floating roller 454. The slider 451 is slidably connected to the first bracket 43 and the second bracket 44 respectively. The two ends of the rotating shaft 453 are rotatably connected to the two sliders 451 respectively. The first elastic element 452 applies a thrust toward the reinforcing ring to the slider 451.

[0042] During the placement of the tank 2, the supporting component 4 gradually closes. The floating roller 454 first contacts the outer circle of the reinforcing ring. As the closure proceeds, the floating roller 454 is compressed. At this time, the slider 451 slides along the slide of the first bracket 43 and the second bracket 44. Since the two ends of the rotating shaft 453 are rotatably connected to the slider 451, the floating roller 454 can adaptively adjust its extension amount as the slider 451 slides. At the same time, the thrust of the first elastic element 452 is transmitted to the floating roller 454 through the slider 451 and the rotating shaft 453, forming a continuous clamping force towards the reinforcing ring so that the reinforcing ring can be attached to the tank 2. After attachment, as the closure continues, the first elastic element 452 will be compressed. In this way, even if the reinforcing ring has a roundness deviation or the outer wall of the tank 2 has a slight unevenness, the sliding of the slider 451 and the rotation of the rotating shaft 453 can compensate for the error together. With the flexible thrust of the first elastic element 452, it is ensured that the reinforcing ring joint is closed and tightly attached to the outer wall of the tank 2.

[0043] Furthermore, the two ends of the rotating shaft 453 are rotatably connected to the two sliders 451. The floating roller 454 is rotated and supported by the rotating shaft 453. The first elastic element 452 continuously applies a thrust to the slider 451 toward the reinforcing ring. When the reinforcing ring is welded to the butt joint, the protruding weld formed at the butt joint rotates with the tank body 2 to the position of the floating roller 454. The weld will generate a radial thrust on the floating roller 454. At this time, the slider 451 slides away from the reinforcing ring along the slide of the first bracket 43 and the second bracket 44. The first elastic element 452 is compressed, which drives the rotating shaft 453 and the floating roller 454 to retract synchronously, thereby avoiding the weld. Other floating rollers 454 that do not contact the weld, because they are not subjected to additional thrust, still maintain close contact with the outer circle of the reinforcing ring under the thrust of the first elastic element 452. It can achieve the synergistic effect of local avoidance and overall support, avoid rigid collision between the weld and the floating roller 454, and ensure that the tank 2 is always in a stable support state during rotation, reduce vibration caused by uneven local force, and ultimately improve the stability of the welding process and the quality of weld formation.

[0044] In the embodiments of the present invention, please refer to Figure 5 and Figure 8It also includes an adaptive removal unit 5, which includes a first gear 51, a second gear 52, a first rotating shaft 53, a first prism 54, a third elastic element 55, a second rotating shaft 56, a second prism 57, a fourth elastic element 58, and a steel brush 59. A pair of second rotating shafts 56 are rotatably connected to a first bracket 43 and a second bracket 44, respectively. The first gear 51 is fixedly installed at both ends of the rotating shaft 453, and the second gear 52 is fixedly installed on the first rotating shaft 53. One end of the first prism 54 is fixedly installed on the first rotating shaft 53, and the other end of the first prism 54 is slidably inserted into the second rotating shaft 56. One end of the second prism 57 is slidably connected into the second rotating shaft 56, and the other end of the second prism 57 is fixedly connected to the steel brush 59. The third elastic element 55 is sleeved on the first prism 54, and the fourth elastic element 58 is sleeved on the second prism 57. One end of the steel brush 59 extends to the weld seam between the tank body 2 and the reinforcing ring.

[0045] When the floating clamping part 45 is working (the rotating shaft 453 rotates with the floating roller 454), the first gear 51 rotates synchronously, driving the first rotating shaft 53 to rotate through meshing with the second gear 52. During power transmission, one end of the first prism 54 is fixedly mounted on the first rotating shaft 53, and the other end is slidably inserted into the second rotating shaft 56. This structure ensures torque transmission through the prism transmission characteristics and allows axial relative movement between the first rotating shaft 53 and the second rotating shaft 56. Furthermore, the third elastic element 55 is sleeved on the first prism 54, which can compensate for the axial displacement error between the first gear 51 and the second gear 52 when the floating roller 454 moves, ensuring the gear... The gear meshing remains stable. The rotation of the second rotating shaft 56 is transmitted to the steel brush 59 through the second prism 57, giving it rotational cleaning power. The fourth elastic element 58 is sleeved on the second prism 57, applying a continuous radial thrust to the steel brush 59. Since one end of the steel brush 59 extends to the weld seam between the tank body 2 and the reinforcing ring, when there is unevenness on the surface of the tank body 2 or the reinforcing ring, the second prism 57 can slide along the second rotating shaft 56. Combined with the elasticity of the fourth elastic element 58, the steel brush 59 always fits the weld seam surface, achieving adaptive cleaning. At the same time, the third elastic element 55 can buffer the axial displacement of the first rotating shaft 53 and the second rotating shaft 56, preventing transmission jamming.

[0046] This structure allows the steel brush 59 to achieve a stable rotational speed through gear transmission during the rotational cleaning process, and also to adapt to workpiece tolerances through the cooperation of the third elastic element 55 and the fourth elastic element 58, effectively removing oxide layers and impurities at the weld.

[0047] In the embodiments of the present invention, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7It also includes an axially extended portion comprising a second elastic element 46, an inclined column 47, and a guide column 48. The second elastic element 46 is slidably sleeved on the transmission shaft 42. The second elastic element 46 applies a thrust to the second bracket 44 to move it away from the first bracket 43. The inclined column 47 and the transmission shaft 42 are coaxially fixedly installed. The end of the guide column 48 is rolledly connected to the inclined column 47.

[0048] In the first state, the elastic force of the second elastic element 46 causes the second support 44 to tend to move away from the first support 43. At this time, as shown in Appendix 3, one end of the guide post 48 is in contact with the inclined surface of the inclined post 47. When the supporting assembly 4 switches from the first state to the second state, the drive shaft 42 rotates around the frame 41, and the inclined post 47, which is coaxially fixed with the drive shaft 42, rotates synchronously. Its inclined surface rolls into contact with the end of the guide post 48. As the rotation angle increases, the inclined post 47 drives the second support 44 to generate axial displacement under the compression of the guide post 48. In this way, the second elastic element 46 is compressed, so that the second support 44 slides smoothly along the drive shaft 42. Finally, the axial distance between the first support 43 and the second support 44 is matched with the width of the reinforcing ring, ensuring that the reinforcing ring always remains centered during axial expansion.

[0049] Furthermore, when the supporting component 4 is in the first state, the second elastic element 46 of the axially extended portion applies a continuous thrust to the second bracket 44, causing the second bracket 44 to slide along the transmission shaft 42 and move away from the first bracket 43, forming a larger gap. In this way, when placing the can, the reinforcing ring can fall naturally between the first bracket 43 and the second bracket 44 without precise calibration.

[0050] The inclined column 47 is fixed coaxially with the drive shaft 42, and its inclined surface is in rolling connection with the guide column 48. In the first state, the excessive displacement of the second bracket 44 is limited by the inclined surface guide, ensuring the stability of the gap size. This not only meets the material feeding space requirements, but also prevents the bracket from detaching from the drive shaft 42. It saves the manual steps of adjusting the relative alignment between the reinforcing ring and the tank 2, thus improving the feeding efficiency.

[0051] In another embodiment of the present invention, the driving assembly 3 includes a base 31, a displacement frame 32, a fifth elastic element 33, a bonding roller 34, an active rack 35, and a passive gear 36. The fifth elastic element 33 is disposed between the base 31 and the displacement frame 32. The bonding roller 34 is rotatably connected to the displacement frame 32. The active rack 35 is fixedly mounted on the displacement frame 32. The passive gear 36 meshes with the active rack 35. The passive gear 36 is fixedly mounted on the support assembly 4.

[0052] It also includes a servo motor, which drives the bonding roller 34 to rotate, so that the tank can rotate during welding.

[0053] Specifically, when the tank 2 is placed on the bonding roller 34, the gravity of the tank 2 causes the displacement frame 32 to move towards the base 31. The fifth elastic element 33 is compressed and generates a reverse elastic force. When the displacement frame 32 moves, the active rack 35 moves synchronously. Through meshing with the passive gear 36, it drives the transmission shaft 42 of the support assembly 4 to rotate, ultimately realizing the switching of the support assembly 4 from the first state to the second state.

[0054] When welding begins, the servo motor drives the bonding roller 34 to rotate (the servo motor is not shown in the attached figure). The bonding roller 34 drives the tank body 2 to rotate synchronously through the friction with the tank body 2, providing a stable rotation reference for the welding of the annular weld. After welding is completed, the tank body 2 is removed, the fifth elastic element 33 pushes the displacement frame 32 to reset, and the active rack 35 drives the passive gear 36 in the opposite direction, so that the support assembly 4 returns to the first state.

[0055] Furthermore, compared to existing technologies, when the reinforcing ring is pressed and bonded, if a unilateral or asymmetrical pressure method is used, the gap between the reinforcing ring and the tank body will fluctuate. This not only increases the risk of defects such as incomplete welding and porosity, but also causes secondary deformation of the reinforcing ring under stress due to excessive local gaps. In contrast, the present invention combines bidirectional radial pressing and bonding with axial clamping positioning, which significantly improves efficiency.

[0056] In another embodiment of the present invention, please refer to Figure 1 It includes a welding robot 1, which is mounted on a track that is set along the axial direction of the tank body 2.

[0057] The welding robot 1 is positioned on a track extending along the axial direction of the tank body 2. The track is parallel to the axis of the tank body 2. When the servo motor drives the bonding roller 34 to rotate and causes the tank body 2 to rotate, the welding robot 1 can move independently along the track. Through the rotation of the tank body 2 and the axial movement of the welding robot 1, continuous welding of the annular weld at the bonding point between the reinforcing ring and the tank body 2 is achieved.

[0058] The welding robot 1 can precisely adjust its starting point along the track according to the axial distribution of the reinforcing rings on the tank 2, without the need to recalibrate the overall equipment position. At the same time, the axial movement of the welding robot 1 can cooperate with the bonding roller 34 of the drive component 3 to ensure the straightness and circumferential consistency of the welding path, avoiding weld deviation caused by axial offset of the tank 2.

[0059] An automatic welding method for reinforcing rings includes the following steps:

[0060] S1, the tank 2 is placed on the drive assembly 3. After the drive assembly 3 detects that the tank 2 is in place, the drive support assembly 4 switches from the first state to the second state. During this process, the floating clamping part 45 positions and clamps the reinforcing ring, so that the butt joint of the reinforcing ring is closed, and the first elastic element 452 makes it fit tightly against the outer wall of the tank 2.

[0061] S2, synchronously, when the first support 43 and the second support 44 are deployed, the second elastic element 46 pushes the second support 44 away from the first support 43, so that the reinforcing ring is deployed in the axial direction. At the same time, the cooperation of the inclined column 47 and the guide column 48 ensures the stability of the deployment process, so as to ensure that the reinforcing ring placed in the tank 2 can fall smoothly between the first support 43 and the second support 44.

[0062] S3, the servo motor drives the bonding roller 34 to rotate, causing the tank 2 to rotate, while the welding robot 1 moves along the track to the welding position; during the welding process, the tank 2 continues to rotate to ensure the uniformity of the welding.

[0063] S4, during the rotation of the tank, the steel brush 59 of the adaptive removal section 5 rotates under the drive of the first gear 51 and the second gear 52 to clean the weld seam of the tank 2 and the reinforcing ring. The third elastic element 55 and the fourth elastic element 58 provide buffering and adaptive capabilities respectively, so that the steel brush 59 can adapt to the unevenness of the surface of the tank 2 and remove the oxide layer and impurities.

[0064] S5, after welding is completed, the tank body 2 is removed, and the drive component 3 drives the support component 4 to switch from the second state back to the first state, releasing the clamp on the reinforcing ring.

[0065] S6, Quality Inspection Steps: This step involves using non-destructive testing technology to inspect the weld seam, as well as recording and tracing welding parameters. The parameters and results of each weld are recorded to facilitate quality traceability and process optimization.

[0066] The automatic welding process for reinforcing rings offers significant advantages: It achieves continuous operation of clamping, cleaning, and welding through mechanical linkage, eliminating the need for robot program adjustments and calibrations between welding operations. Furthermore, the continuous thrust of the first elastic element 452 in the floating clamping part 45, and the cooperation between the inclined column 47 and the guide column 48 in the axially expanding part, along with other structural elements, ensures stable positioning of the reinforcing ring, reducing welding defects caused by deviations. The simultaneous cleaning by the steel brush 59 in the S4 stage, combined with the rotational welding of the tank body 2, efficiently removes impurities and ensures uniform weld formation. The first elastic element 452 enables flexible clamping, adapting to different tank body 2 and reinforcing ring specifications, and the entire process is mechanically linked without the need for manual adjustments.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

7. An automatic welding method for reinforcing rings, implemented based on the automatic welding system for reinforcing rings as described in claim 6, characterized in that, Includes the following steps: S1, the tank (2) is placed on the drive assembly (3). After the drive assembly (3) detects that the tank (2) is in place, the drive support assembly (4) switches from the first state to the second state. During this process, the floating clamping part (45) positions and clamps the reinforcing ring, so that the butt joint of the reinforcing ring is closed, and the first elastic element (452) makes it fit tightly against the outer wall of the tank (2). S2, synchronously, when the first support (43) and the second support (44) are deployed, the second elastic element (46) pushes the second support (44) away from the first support (43), causing the reinforcing ring to be displaced in the axial direction. At the same time, the cooperation of the inclined column (47) and the guide column (48) ensures the stability of the deployment process, so as to ensure that the reinforcing ring placed in the tank (2) can fall smoothly between the first support (43) and the second support (44). S3, the servo motor drives the bonding roller (34) to rotate, causing the tank (2) to rotate, while the welding robot (1) moves along the track to the welding position; during the welding process, the tank (2) continues to rotate to ensure the uniformity of the welding; S4, during the rotation of the tank, the steel brush (59) of the adaptive removal part (5) rotates under the drive of the first gear (51) and the second gear (52) to clean the weld seam of the tank (2) and the reinforcing ring. The third elastic element (55) and the fourth elastic element (58) provide buffering and adaptive capabilities respectively, so that the steel brush (59) can adapt to the unevenness of the surface of the tank (2) and remove the oxide layer and impurities. S5, after welding is completed, the tank (2) is removed, the drive assembly (3) drives the support assembly (4) to switch from the second state back to the first state, and releases the clamp on the reinforcing ring; S6, Quality Inspection Steps: This step involves using non-destructive testing technology to inspect the weld seam, as well as recording and tracing welding parameters. The parameters and results of each weld are recorded to facilitate quality traceability and process optimization.
