Effect of Welding Parameters on Mechanical Properties of Friction Stir Welding of Dissimilar Metals- A Review

Abstract

This review article summarizes the extensive research works carried out on welding parameters (tool rotational speed, traverse speed, pin profile, axial force and tilt angle) effect on mechanical properties of FSW of dissimilar alloys. Extensive studies were being carried out by joining different materials using friction stir welding for different automobile and aerospace applications. FSW process takes place in the solid stage below the melting point of the metals to be joined and numerous materials including, aluminum, bronze, copper, titanium, steel, magnesium, and plastic can be welded. FS welded joints gives more strength and toughness when compared to fusion welded joints. FS welding technique is being used in many research institutes and production companies in the world.
