Abstract :

Resistance spot welding is commonly used in the automotive industry. because it has the advantage which is high speed, high–production assembly lines and suitability for automation. The objective of this paper is to find out the influence of the various process parameters on the tensile shear strength of the resistance spot welded joints for low carbon steel. The problems associated with RSW are tendency of alloying with the electrode resulting in increased tool wear, and subsequent deterioration of weld quality. More current and time lead to expulsion and overheating of the electrode, affecting the weld quality and less value result in insufficient weld strength. The complicated behavior of this process must be analyzed to set the optimum parameters to get good quality weld. The experimental studies were conducted under varying welding current, welding time, electrode diameter and electrode force. By doing the analysis, an optimum parameter combination for the maximum tensile shear strength was obtained. The settings of the process parameters were determined by using Taguchi’s experimental design method. Orthogonal arrays of Taguchi, the signal–to–noise (S/N) ratio, the analysis of variance (ANOVA) employed to find the optimal process parameter levels and to analyze the effect of these parameters on tensile shear strength values.
