Abstract

The aim of this research is to improve the Resistance Spot Welding (RSW) process characteristics of AISI SS316L joints on tensile shear load (TSL). The RSW process parameters like electrode diameter of 6mm to 8mm, welding current of 7 kA to 9 kA, heating cycle periods of 7 to 9 are selected. The 2 mm sheet thickness has been selected for the welding trials and tensile shear test has been involved for all the trials for the purpose of identifying the TSL. Taguchi optimization technique is used for design the experiment with the help of Minitab software. It is observed that maximum TSL of 16 kN is observed by setting the parameters at 6mm electrode diameter, 9 kA welding current and heating cycles of 9. The ANOVA table confirms that welding current majorly affects the quality of weld and all the trials are observed with interfacial failure
