Abstract

In this study, Aluminium alloy 5052 sheets were joined using Friction Stir Welding machine and the process parameter were optimized using Taguchi L9 Orthogonal Array design of experiment. Two process parameter which are spindle speed (rpm) and welding speed (mm/s) were considered under this study. Signal-to-Noise ratio (S/N) and Analysis of Variance (ANOVA) were used to identify the significant welding parameters affecting the joint tensile strength. Two factors with three levels orthogonal array were developed by application of Minitab software. A total of nine numbers of trial run (L9) were used to optimize the process parameters to attain the optimum joint strength in the stir welded samples. The tensile strength was considered as the quality characteristic with the objective concept of “larger is better”. The predicted optimum value was confirmed by conducting the confirmation test using the optimum combined parameters. Analysis results from Signal-to-Noise ratio (S/N) and the Analysis of Variance (ANOVA) have indicate that the optimum joint tensile strength was at 8000 rpm spindle (level 1) and 5mm/s weld rate (level 1)or B1A1.
