Abstract—Resistance spot welding is the process of joining sheet metal this welding process is fusion welding process where both heat and pressure are applied on the joint. There is no filler metal or flux is added. The heat necessary for the melting of the joint is obtained by the heating effect of the electrical resistance. Resistance spot welding applications are automobile industries, rail coach manufacturing, aerospace and nuclear sectors, electric and electronic industries. In the present work the peel test is carried to know the strength of the spot weld experimentally and also using finite element analysis for different combination of dissimilar materials to evaluate the stresses. Thermal analysis is also carried out to know temperature distribution.
