Abstract

In this paper, the finite element method is used to simulate the welding process of titanium/stainless steel dissimilar material with copper as the transition layer by ring oscillation laser welding, and the reliability of the finite element model is verified by experiment. The influence of laser power and welding position on the weld temperature field under different welding paths was studied. It is found that the optimum weld pool width can be obtained by using 2200W laser power and ring oscillation laser welding along the center of the Cu transition layer. When the stainless steel side is offset by 0.2mm for welding, the heat-affected zone area can be reduced to the greatest extent, the melting amount of the titanium matrix can be reduced, the formation of titanium-copper intermetallic compounds can be inhibited, and the mechanical properties of the welding joint can be improved.
