Description

Technical Field

[0001] The invention relates to the technical field of steel structure welding, and in particular to a building steel structure welding device and a welding method. Background Art

[0002] During the welding process of building steel frames, the quality of the weld seams plays a relatively important role in the connection and support performance of the steel structure. In the actual welding process, since some steel structures have not been completely fixed, the welding area is not easy to align, and the handheld welding gun is easy to shake during welding, resulting in large errors and poor effects of the weld seams at the connection position of the steel structure, affecting the connection performance between the steel structures. Therefore, when performing connection welding of steel structures, in order to align and stabilize the welding areas between the steel structures, corresponding welding devices are often used for auxiliary welding.

[0003] The invention patent with announcement number CN115091108A discloses a welding fixture and welding method for building steel structures. When performing connection welding of steel structures, the welding position between the auxiliary steel rod and the main steel frame is aligned and stabilized, and the welding gun and the welding seam are also ensured to be smoothly aligned, completing the welding process more evenly and linearly, thereby improving the quality of the welding seams between steel structures.
