Abstract
The invention relates to the technical field of welding, in particular to a welding method for end wall components of a railway wagon. The welding method for the end wall component of the railway wagon comprises the steps that the end wall component is divided into a first part and a second part which are symmetrical; a first welding robot is adopted for welding a welding seam in the first part of the end wall component, and a second welding robot is adopted for welding a welding seam in the second part of the end wall component at the same time; and cleaning the welding gun and the welding surface to finish welding. According to the welding method for the end wall component of the railway wagon, due to the fact that the welding robot is adopted for automatically welding the welding seams in the end wall component, compared with the related technology, the welding efficiency is greatly improved, the labor condition of an electric welding operator is improved, welding arc light, splashing, smoke dust and high-temperature damage are reduced, and work safety is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of welding, in particular to a welding method for end wall components of railway freight cars. Background technique [0002] The end wall components are an important part of the entire railway freight car body. Most of their structures are welded together by plates and profiles. The welds are mostly long straight welds, including lap welds, butt welds, and crimping welds. etc., the welding workload is large, and in the related art, the end wall components are welded by hand, resulting in low welding efficiency and a harsh working environment for the operator. SUMMARY OF THE INVENTION [0003] The present application provides a welding method for end wall components of a railway freight car, which solves the technical problems of manual welding of end wall components in the related art, resulting in low welding efficiency and harsh working environment for operators. [0004] The present application provide...
