Description

Technical Field

[0002] At present, welding equipment refers to the equipment required to realize the welding process. Welding equipment includes welding machines, welding process equipment and welding auxiliary tools. The existing welding equipment is not equipped with a special fixing device for the welded parts. In the process of welding cold metal, it is easy to cause the cold metal to move if it is not fixed by the fixing device, thereby causing welding failure. In addition, the existing welding equipment can only fix cold metal of a certain specification. When the cold metal is too long, the welding equipment will not be able to fix the cold metal, which has certain limitations.

However, when the metal structural part is tightened by the spring, not only is the stability poor, but when the position of the metal part to be welded is not aligned, it needs to be disassembled and replaced. The position adjustment process of the metal structural part is cumbersome and time-consuming, resulting in reduced work efficiency. In addition, the metal structural part cannot be adjusted at an angle. When the metal structural part needs to be welded at an angle, it has great limitations and is not convenient to use.
