Optimization Of Process Parameters For Peak Temperature During Friction Stir Welding Of Aluminum Alloy

Abstract Friction stir welding is a solid state joining method used to join materials which cannot be joined by fusion welding. In this method, heat produced due the friction between tool and workpiece weld material. Heat input depends upon amount of caused process parameters such as rotational speed, geometry, axial force etc. present study, effect shoulder pin diameter ratio, speed on peak temperature obtained during aluminum alloy were investigated using taguchi L9 orthogonal array. ANOVA result shows that ratio (D/d) most significant factor affecting FSW.
