Abstract
Welding the steels using aluminum have greater applications, and this combination will help to decrease the overall weight of assembled units. Two metals with dissimilar thickness will be aligned in lapped position wherein a spot weld, it is performed using non-consumable pin profiled tool. Welding is performed based on the friction generated by the rotating tool on the dissimilar metals. This heat generated during the friction helps the dissimilar metals AA6062 with the structural steel ST1020 to join which are taken with thickness of 0.3, 0.5 and 0.7 mm with a rotating tool made of ‘H13’ material and pin profile is taper at the end. Three parameters with three levels have been used to perform joining operation. Minitab software is used for design of experimentation, and ANOVA is utilized for the validation of larger the better.
