Experimental and Numerical Investigations of Temperature Measurement of St12 Friction Stir Welded Butt Joints

The effect of processing parameters on mechanical properties of st friction stir welded (FSW) joints were investigated in present study. Different welded specimens were produced by employing variable rotating speeds, welding speeds, axial forces and tool pin profiles. The accurate D finite element simulation of FSW process was conducted on st plates with a concave tool. The numerical simulations are based on an Arbitrary Lagrangian Eulerian (ALE) formulation that has been implemented in ABAQUS software. The experimental and simulation results indicated that every increasing in plunge depth, contributed to rising in temperature and axial force.
