Characterisation of Aluminium and Copper Weld Joints during Friction Stir Welding

Abstract: The present study evaluates the mechanical properties of weld Joint of alloys of aluminium and copper joined by Friction Stir Welding (FSW)". In this study, different alloys of aluminium by varying amounts of copper by stir casting process were prepared. The prepare alloys were welded by Friction Stir Welding under fixed parameters. Mechanical properties of alloys of welded joints are determined. The mechanical properties and microstructures of different alloys of welded joints are analysed. The study revealed that the alloy which has four percent of copper exhibited good results in all respects. Keywords: Friction Stir arc welding.
