In the present study a comprehensive numerical study has been conducted to simulate the resistance spot welding process. The phase- field method is employed to model the phase change during the melting and solidification of the material. By this way, the martensitic properties are assigned at the nugget and heat affected zone. As a result of this modelling the residual stress at the heat affected zone is attained and shows maximum value on the heat affected zone.
