The Optimization Conditions of Friction Stir Welding (FSW) for Different Rotational and Weld speeds
مجلة النهرين للعلوم الهندسية, 2012 The effect of welding parameters on mechanical properties of aluminum alloy 3003 H14 Friction stir-welded (FSW) joints were investigated in the present study. Different welded specimens were produced by employing variable rotating speeds (1000, 1250, 1500, 2000 r.p.m.), and welding speeds (20, 40, 60, 80 mm/min).
