Description

Large-scale steel structure welding device

Technical Field

The utility model relates to a large-scale steel constructs welding technology field, specifically is a large-scale steel constructs welding set.

Background

The steel member is a steel structure combined member which is formed by connecting steel plates, angle steels, channel steels, I-shaped steels, welded or hot-rolled H-shaped steels through connecting pieces in a cold bending or welding manner and can bear and transfer loads. Steel components are used reasonably and widely in the field of construction engineering in the global context, particularly in developed countries and regions. Practice shows that the larger the acting force is, the larger the deformation of the steel member is. However, when the force is too large, the steel member will be broken or severely and remarkably plastically deformed, which will affect the normal operation of the engineering structure. In order to ensure that engineering materials and structures work normally under load, each steel member is required to have sufficient load bearing capacity, also called bearing capacity. The magnitude of the load bearing capacity is primarily measured by the sufficient strength, stiffness and stability of the steel member. Strength refers to the ability of a steel member to resist failure (fracture or permanent deformation). Namely, the yield failure or the fracture failure does not occur under the action of load, thereby ensuring the capability of safe and reliable work. Strength is a fundamental requirement that all load bearing members must meet, and stiffness refers to the ability of the steel member to resist deformation. If the steel member is deformed too much after being stressed, the steel member cannot work normally even if the steel member is not damaged. Therefore, the steel member must have sufficient rigidity, that is, not be allowed to fail in rigidity. The angle adjustment of a welding gun of the existing device for welding the large steel member is limited, and the welding deviation condition can occur in the welding process.
