Orthogonal Optimization of Technological Parameters for Resistance Spot Welding of 00Cr18Ni10N Stainless Steel

The spot welding process for 00Cr18Ni10N stainless was optimized by orthogonal experiment.The optimum process is,welding current 5800~6300 A,electrode pressure 5.1~6.0 KN,welding time 6~9 cyc.The results show that welding time has great effects on the single point shear resistance of spot welding joint,and then is ourrent,electrode pressure in turn.
