Examination of Friction Stir-Welded AA 6262/5456 Joints through the Optimization Technique

Friction stir welding (FSW) is the solid state technique which mostly utilized to join similar and dissimilar Al, Cu, Mg, their alloys. This research investigated that tensile strength of FSW Al6262 Al5456 4 mm thickness carried out using an H-13 tool pin along with different process variables such as rotational speed (TRS), (WS), tilt angle (TTA). The selected parameters are set TRS 900, 1100, 1400 rpm, WS 20, 30, 40 mm/min TTA 2, 2.5, 3° find significant on (TS). Taguchi L27 method taken create a number experiments recognize optimal level each parameter accomplish highest TS value. From experimental results witnessed, extreme (202.44 MPa) acquired at sample 22 when maintaining TRS-1400 WS-30 mm/min, TTA-2 degree, whereas minimum (165.88 attained 15 TRS-1100 TTA-3 degree. ANOVA outcome revealed most factor (23.24%) improves property joints, followed by weld 21.7% combination (16.17%). increment in does not play vital role improving value, MINITAB -17 software helped relation between regression equation.
