Process Optimization of Cold Metal Transfer Plug Welding of Aluminum AA6061-T6-to-Galvanized DP590 Steel Based on Orthogonal Experiment Method
In this paper, cold metal transfer (CMT) plug welding of aluminum AA6061-T6-to-galvanized DP590 steel is studied using AlSi-5 welding wire as filler material.The influence of wire feeding speed on welding quality is one of the research emphases.Firstly, an orthogonal experiment is designed to investigate the impact of wire feeding speed, welding sp
