Effect of Process Parameters during Friction Stir Welding of Al 6063 Alloy

Abstract:

In the Present paper, the effects of axial force, rotational speed of the FSW tool, welding speed and shoulder penetration on various mechanical properties of Aluminium alloy 6063 butt joint produced by Friction Stir Welding have been analyzed. The mechanical properties like tensile strength, Yield strength and % Elongation have been tested using 6 mm thickness plate. The tool used for conducting the experiment was Hot Die Steel (HDS). The welding quality can be improved by enhancing the mechanical properties and minimizing the defects. Hence, analysing & examining the mechanical or physical properties and other relevant significant factors would help to enhance the weld reliability. Tensile Strength (TS), Percentage of Elongation & Yield Strength (YS) of FSW Al 6063 alloy has been carried out under different processing condition using Taguchi’s experimental design. An optimum result has been obtained using main effects plot using S/N ratio values. The rotation speed of the FSW tool has been found dominant factor for TS followed by feed and shoulder penetration. Shoulder diameter shows the least effect on TS compared to parameters like Percentage of Elongation & Yield Strength (YS).
