| Abstract Scope |
This research work presents an experimental investigation into friction stir welding (FSW) of AA6061-T6 and Ti6Al4V alloys with a nickel interlayer, followed by the optimization of process parameters. FSW is a promising as well as environmentally friendly approach for joining dissimilar and difficult to join materials. Due to the dissimilar properties of aluminium and titanium alloys, challenges arise in welding them together. The incorporation of a nickel interlayer aims to enhance weld quality by mitigating intermetallic formation and improving mechanical properties. Variation of friction stir welding parameters, including rotational speed, traverse speed, and tool pin diameter, is systematically conducted. The microstructural evolution and mechanical performance of the joints are analyzed through microscopy and tensile testing. The insights derived from this study offer valuable contributions to friction stir welding for the dissimilar Al/Ti alloys and optimization, thereby facilitating their application in aerospace, automotive, and various other industries requiring lightweight, high-strength materials. |
