Abstract: This paper presents an experimental investigation for the Tensile Shear (T-S) strength and Nugget diameter of resistance spot weld by using Taguchi method. An experimental study is conducted under various levels of process parameters. Spot welds are carried out on Stainless Steel (304) material. Welding current; Electrode force and Weld time are process parameters with three levels of each. Taguchi quality design concept of L27 orthogonal array has been used to determine S/N Ratio; Analysis of Variance (ANOVA). The level of importance of welding parameters for T-S strength and Nugget Diameter are determined by ANOVA in Minitab 16 software.
