Optimization of Process Parameter on AA8052 Friction Stir Welding Using Taguchi’s Method

The Taguchi method of experimental design was employed in this study to scrutinize the impact welding processing factors, including rotating speed, travelling and pin profile on ultimate tensile strength, microhardness, strength Friction Stir Welded AA 8052 joint. S/N values for each process specification were calculated using an orthogonal array L9 design. 1150 rpm 28.5 mm/min greatest evaluation parameters, respectively, a used cylinder pin. A combination 32.5 mm/s conical cylindrical provided best toughness results. According analysis variance, spinning travel feed, shape had 37.34% further 34.33% microhardness. second set tests verified findings, with 349.96 MPa, hardness 115.31 H, 7.95 kJ.
