[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. Angle steel can be used to form various load-bearing components according to different needs, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, and warehouse shelves.

[0003] When processing angle steel, it is often necessary to butt-weld the edges of two angle steels into a rectangular steel pipe. The two angle steels need to be clamped and fixed during welding. However, in the existing technology, it is not convenient to initially fix the angle steel, and the clamping efficiency is low. Therefore, we have introduced an angle steel welding fixture.
