Influence of Welding parameters on Mechanical property during Friction Stir Welded joint on Aluminium Alloys: A Review

The friction stir welding (FSW) is widely used in the fabrication of Aluminium alloy and other non-ferrous alloy. It has good potential to be major industries such as automobiles, aerospace, shipbuilding can joining high strength alloys. FSW process low distortion heat affected zone (HAZ) with fine recrystallized microstructure which leads better mechanical properties at weld produces great stability. In this study, different parameters speed, tool rotation tilt angle, feed per min been discussed. types pin profile shoulder have also discussed their impacts on microstructural welded joints. Among various rotational speed most influencing parameter FSW. Increasing exhibits increase tensile supposed improve properties. would considered tapered threaded cylindrical makes adequate mixing material flow ability provide grains nugget zone. Comparing arc processes, it shows a wide range environmental benefits are noticeable saving consumable materials, decrease consumption filler reduction grinding wastes. Harmful emissions created from causes health hazard welder. For achieving joint-strength for aerospace aluminium alloys temperature sustainable metallic alloys, will preferred.
