Friction Stir Welding of Aluminum 6082 with Mild Steel and its Joint Analyses

A B S T R A C T Friction stir welding is carried out on 6mm thick plates of Al 6082 alloy and mild steel, where various welding parameters like, tool rotation speed (rpm), welding speed (mm/min) have been optimized and a suitable range for all parameters is achieved. After welding, good samples are selected and small specimens are cut from it perpendicular to the weld direction for microhardness and tensile tests. In this research study, the significance of placing the material on advancing and retreating sides especially during the welding of dissimilar materials has been checked, with the help of microstructural characterization technique like energy dispersive spectroscopy (EDS) analyses
