Effect of Different Tool Geometries in Friction Stir Welding of AA 2024-T3 using Design of Experiments

In this work, Aluminum alloy (AA2024-T3) was welded by friction stir (FSW) method using different pin profile design types; straight cylinder, threaded cylinder, tapered cylinder hexagonal, square, and threaded taper. For each type, a flat and concave shoulder was used, as well as, the welding proc...
