Description

Technical Field

[0001] The present invention belongs to the technical field of welding equipment. Specifically, it particularly relates to a welding equipment and a welding method for capping beam processing. Background Art

[0002] A capping beam refers to a cross beam provided at the top of a row of pile piers to support, distribute, and transfer the loads of the upper structure; the framework of the capping beam is usually welded by steel bars;

[0003] In actual production, usually after the capping beam steel bars are fixed, welding is directly carried out. However, there are usually rust and impurities on the surface of the capping beam steel bars. The rust and impurities on the surface of the capping beam steel bars will affect the welding quality, resulting in welding defects such as insecure welds and pores. The traditional manual grinding method is time-consuming and laborious, with low efficiency and cannot meet the requirements of large-scale production; the traditional fixing method can often only adapt to a single welding requirement, and for different forms of welding (such as parallel welding and cross welding), different fixed connections need to be replaced, increasing the processing steps and costs. Summary of the Invention
