Description

Technical Field

[0001] The present invention relates to a relatively wide range, and in particular to a welding processing device and method for a bridge steel structure. Background Art

[0002] In the processing of bridge steel structures, such as bridge U ribs, U ribs are widely used in various types of steel structure bridges. They are important reinforcement components of bridge plate units. They can achieve uniform stress on the bridge deck steel plate units and significantly enhance the stress performance of the bridge deck. According to the requirements of the drawings, the plate is cut and the processed U ribs and base plates are welded together. The groove is processed by a semi-automatic flame cutting machine. The groove surface and the areas to be welded on both sides of the groove must be polished clean and kept dry. After assembly, welding is performed. U ribs have the characteristics of a large number of welds, long welds, and a large amount of welding.

[0003] In the existing bridge steel structure welding processing device, when welding U rib plates, since multiple U ribs need to be welded and connected, multiple welding machines in the welding processing device are not conducive to synchronous adjustment, which means that each U rib may need to be positioned and welded separately, which will greatly increase the welding time and reduce the overall work efficiency. It may cause the U rib plate to be displaced or deformed during the welding process, thereby affecting the accuracy and quality of the weld. In addition, the asynchronous welding machines and unstable fixing methods may increase safety hazards during the operation, such as welding spatter. To this end, a bridge steel structure welding processing device and method are proposed. Summary of the invention
