Optimization of Resistance Spot Welding Process Parameters for Tensile Strength of Dissimilar Welded Joint

Jeevan A. Karande, Dr. K. H. Inamdar

Abstract: In vehicle and aviation enterprises resistance welding process is most ordinarily utilized for joining sheet metal. Around 6000-8000 spot welds are required in any automobile, which demonstrates the extent significance of the protection spot welding. It is a muddled procedure, as it includes cooperation of the mechanical, heat, electrical and metallurgical discipline. This paper presents an experimental investigation for the Tensile Shear (T-S) strength 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 (304L) and Aluminium 6061-T6 material. Dissimilar joining of aluminium and steel, particularly utilizing resistance spot welding is a critical Process. Welding current, Electrode force, Squeeze Time and Weld time are process parameters with four levels of each. Taguchi quality design concept of L16 orthogonal array has been used to determine S/N Ratio, Analysis of Variance (ANOVA). The level of significance of welding parameters for T-S strength is located out by ANOVA in Minitab 17 software.
