A REVIEW OF FRICTION STIR WELDING OF ALUMINIUM ALLOYS-IJAERD
Keywords:
-Abstract
Friction stir welding is a solid state joining process. High strength aluminium alloys are widely used in
aircraft and marine industries. Generally, the mechanical properties of fusion welded aluminium joints are poor. As
friction stir welding occurs in solid state, no solidification structures are created thereby eliminating the brittle and
eutectic phases common in fusion welding of high strength aluminium alloys. In this review the process parameters & its
effects on mechanical properties & microstructure and macrostructure, specific to aluminium alloys have been
discussed.
