Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a welding device used for steel structures. Background Art

[0002] Steel structure is a structure made of steel material, which is one of the main types of building structures. Steel structure is easy to rust, generally steel structure needs to be rust-proofed, galvanized or painted, and regularly maintained. The characteristics of steel are high strength, light weight, good overall rigidity, and strong resistance to deformation, so it is particularly suitable for building large spans, super-high and super-heavy buildings.

[0003] Publication No. CN220943800U discloses a welding device for steel structure connection, which can adjust the height of the platform by installing a cylinder, and adjust the distance between the steel structure and the welding gun according to the different thickness of the steel structure, so as to improve the practicality of the welding equipment and make it flexible to use. However, in the process of use, because different needs require steels of different shapes to be fixed by welding, the equipment can only adjust the height but not the width, which has certain limitations in use during construction. To this end, we propose a welding device for steel structure. Utility Model Content
