Ahmet Atak, Aydin Sik, Veysel Ozdemir

In this paper, friction stir spot welding (FSSW) of magnesium sheets were analyzed using finite element method (FEM). Various tool shoulder types used in Friction stir welding (FSW) were chosen as different parameter. Thermic simulations were showed that thermic conditions vary with tool shoulder design types used in friction stir welding. Heat energy input (Q) of numerical model was solved analytically and calculated based on the various parameter values. Friction factor surface pressure and materials thermic properties which are changing with generated heat during friction welding were also considered in the FEM analysis. Thermic field model was solved numerically and results were presented.
