Optimization of Friction Stir Welding Parameters of AA5052-H32 Aluminium Alloy using Taguchi and Taguchi-Pareto Methods

It is difficult to improve the quality of friction stir welded joints AA5052-H32 material because scarce metrics on its concurrent optimization and prioritization. However, objective this article obtain optimal parametric values identify important parameters using Taguchi-Pareto method during welding process material. Then ranks, delta are determined. The critical identified for tool pin, rotational speed, speed angle. When comparing results these Taguchi method, retained first position in both methods; tilt angle gained second from third when only was considered. became against that it had method. pin profile last methods. Consequently, best parameter while worst parameter. For setting TPP2/TPP4RS1WS4TTA3. This interpreted as cylindrical tapered or square profile, 40 rpm 75 mm/min 1.5° novelty study scope analysis extends beyond where prioritization achieved.
