Description

A welding tool for steel structure welding

Technical Field

The invention relates to the technical field of steel structure welding, in particular to a welding tool for steel structure welding.

Background Art

Steel structure welding refers to the process of connecting steel materials, usually by welding to connect different components or different parts of components to build a structure with load-bearing capacity;

When welding cylindrical structures, the traditional welding method is to align two groups of columns by hand, then weld at a single angle, and then rotate part of the welded material synchronously to weld at a different angle. The above welding process has the following problems:

1. Unstable alignment. Manual alignment is prone to unstable alignment of material end faces, resulting in poor welding results. In addition, manual alignment is easily affected by the external environment.

2. Poor welding stability. When welding, welding can only be performed on a single side of the material within a certain angle range. Some angles can only be exposed by rotating the material. When rotating the unwelded material, the end face is prone to break again;

3. It is inconvenient to adjust the welding angle. When welding some materials, the welding head needs to be at a certain angle to the material to complete the welding. However, manual support is used, which makes it inconvenient to adjust the angle and affects the welding quality.
