Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, 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. When the steel structure is in use, it is necessary to splice the steel structures with each other and perform welding to ensure sufficient stability between the steel structure components.

[0003] In the process of splicing existing steel structures, the steel structures that need to be butted are usually butted together, and welding equipment is used to weld the joints to ensure the stability of the steel structure. However, in actual use, due to the certain weight of the steel structure itself, it is difficult to butt together during the splicing process, and it is easy to tilt and shake, resulting in ineffective welding. In addition, during the welding process, the steel structure is prone to shaking, which affects the quality of welding and thus affects the stability of the steel structure. Therefore, a steel structure welding device is proposed to solve the above problems. Utility Model Content
