[0002] Thin-walled workpieces refer to parts or products with relatively thin wall thicknesses. In industrial production, thin-walled workpieces are a common type. Because of their simple structure, light weight, and low manufacturing cost, they are widely used in many fields, such as the automotive industry, construction industry, electronics industry, aerospace industry, and other industrial fields.

[0003] Long cylindrical thin-walled workpieces are usually formed by welding. When two long cylindrical thin-walled workpieces are welded at the joint, generally, workers fix the outer sides of the long cylindrical thin-walled workpieces through tooling, and then directly weld at their joints. This not only has poor stability but also is inconvenient for docking. Therefore, there is an urgent need for a welding tooling for long cylindrical thin-walled parts to overcome the above defects.
