Abstract

Resistance spot welding is an extensively used welding process for joining thin metal sheets in automobile, rail and aircraft industries. The resistance spot weld must have shear strength which is equal to the base metal shear strength and must exceed the strength of a rivet or a fusion plug weld of same cross sectional area. Shear strength is generally recognized as the criteria for resistance spot weld stipulations, while other methods may also be used. In this research work spot welding of two dissimilar metals namely AISI 316 and AISI 202 is carried and its tensile strength and hardness is studied to accomplish optimum tensile strength of the weld joint and hardness of the weld joint. Internal flaws due to increase in the current value have also been analyzed.
