[0002] Welding, as a core manufacturing process and technology, plays an indispensable role in the industrial field. It combines metal or other thermoplastic materials (such as plastic) at the atomic level through heating, high temperature or high pressure, forming a solid and durable connection. This technology is not only widely used in construction, aerospace and other industries, but also is an indispensable part of the automotive manufacturing industry.
[0003] In the process of automobile manufacturing, especially for the connection of automobile pipeline, welding technology plays a key role. Therefore, before welding, a specially designed clamp must be used to accurately butt joint and position the pipeline to be welded, ensuring that the two sections of the pipeline can perfectly fit together and avoid any deviation that may affect the quality of the weld. Only when the pipeline is accurately fixed, the pipeline can be welded to ensure the quality of the welded joint.
[0004] During the pipeline welding process, in order to ensure the integrity and quality of the weld, it is usually necessary to fully weld the entire circumferential weld. This means that the welder must perform continuous welding operations around the pipeline until a complete welded joint is formed. However, in actual operation, due to the size and position limitations of the pipeline, the welder often cannot complete the welding of the entire weld in one operation, but needs to do it in sections. Such an operation process, while helping to ensure the quality of the weld, undoubtedly increases the additional time and workload of frequently loosening, adjusting and re-clamping the clamp, thereby significantly reducing the welding efficiency.
