Technical Field

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

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

[0003] In steel structure welding, when welding between steel frames and steel plates, the steel plates need to be fixed on the steel frames by welding.
