Research on electric rivet welding process and its application to sheet welding

In this paper,the application of electric riveting welding technique to the manufacturing of thin plate welding structure was studied.Through series of welding procedure tests and welding procedure qualification tests of electric rivet welding,the welding parameters of electric rivet welding were optimized,the rationality of electric rivet welding procedure was verified,and the most reasonable parameters of processing hole and welding parameters suitable for sheet covering structure were proposed. The deformation that happened in electric rivet welding process is obviously smaller than that of the plug welding procedure,which can significantly reduce the welding deformation and the flattening work and ensure the appearance quality of the structural parts to improve the commercialization degree of the wagon.
