Abstract
Friction stir welding (FSW) was used to combine two different Al-Cu alloys, AA2618-T87 and Al-Mg alloy AA5086-H321 plates, and the characteristics of the procedure were adjusted using Taguchi L16 orthogonal experiments planned in advance. Consideration was given to a variety of factors including rotational and cross-sectional speeds, geometry, and the tool-to-pin-diameter ratio The tensile strength of the joint was used to identify the best procedure parameters. Runs with the ideal settings confirmed the projected optimal tensile strength value. A wide range of process parameters can be used to generate high-quality joints, according to this study. According to the results of an analysis of variance, the most important factor in determining the soundness of a joint is the fraction of tool contact area to pin diameter, although pin shape and welding speed also have a major impact. During this examination, it was observed that the nugget region is dominated by material on the forward-moving side. Heat-affected zones with tensile failures occurred on the alloy 5086 side of the weldment.
