Study on the Laser Welding Process of WCe20 Cerium Tungsten Alloy and Tantalum
According to the structural characteristics and welding technical difficulties of cerium tungsten alloy and tantalum parts,the welding process test is conducted by laser welding,the orthogonal test design scheme is selected,and the influence of welding power,welding speed and defocus quantity on the weld melting depth is determined through the differential analysis.The metallographic detection and helium mass spectrum detection are conducted.Through the experimental study,the optimal welding process parameters are obtained,and the welding forming of cerium tungsten alloy and tantalum parts is realized,and the high quality and reliable welding joints are obtained.
