Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding equipment, in particular to a steel structure welding device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welding. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] During use, in order to meet actual production needs, it is necessary to weld the same or different steel structures to achieve the rationality of specifications or structures. When welding two smaller steel structures, the traditional process first requires the two parts to be welded to be manually aligned, and then clamped and fixed for welding, which increases the labor intensity. When welding larger steel structures, lifting equipment is required to lift the steel structures, which causes a waste of resources. In addition, when the steel structures are turned over, if manual turning is used, the labor intensity will be further increased. If lifting equipment is used, the welding efficiency of the steel structures will be reduced. For this reason, we propose a steel structure welding device. Utility Model Content
