Optimum Welding Parameters for Friction Stir Welded AA6063 Pipe Butt Joint Using the Taguchi Method

Welding parameters for pipe joint friction stir welding (FSW) have been identified based on L-9 orthogonal arrays used in the Taguchi Method. Different parameters, such as rotation speed, travel speed and axial force, to produce several quality welded AA6063 butt joints. The reliability of products obtained FSW process can be improved through identification optimum combination parameters. Weld was evaluated its tensile strength residual stress profiles. S/N analysis Analysis Variance (ANOVA) determine significant that affect weld quality. Maximum with acceptable at 1300 rpm, 5 mm/s force between 6 kN. goal this study optimize high low stress.
