A Study of the Optimization and Characterization of Friction Stir Welded AA5083 and AA6082

The joining of dissimilar 6mm thickness plates AA6082 & AA5083 was carried out using the friction stir welding (FSW) technique. process parameters are optimized Taguchi L9 orthogonal design experiments. Where rotational speed (600, 900, 1200 rpm), travel (60, 90, 120 mm/min), and tilt angle (0, 1, 2◦ ) were taken into consideration. optimum determined with reference to tensile strength, yield stress, elongation joint. Friction aluminum alloys has gained popularity in manufacturing industries such as shipbuilding, aircraft production, railways, automotive. Effect on properties, microstructure, hardness distribution welded joints investigated.
