[0001] The present invention relates to the technical field of welding equipment, and specifically relates to a welding tooling for the manufacture and construction of steel box girders. Background Technique

[0002] Steel box girders are generally used in bridges with large spans and are called steel box girders because their appearance resembles a box. A steel box girder is generally formed by connecting a top plate, a bottom plate, a web plate, a diaphragm plate, a longitudinal diaphragm plate, stiffening ribs, etc. through a full-welding method. The top plate is an orthotropic bridge deck composed of a cover plate and longitudinal stiffening ribs.

[0003] During the construction welding process of steel box girders, welding tooling is required. Welding tooling is a set of flexible welding fixtures for fixing, pressing, and positioning, mainly used for welding various weldable materials. Using welding tooling can accelerate the welding rate. Currently, the welding tooling cannot be adjusted and can only weld at one angle, with a relatively limited scope of application.
