Experimental Investigation and Optimization on Friction Stir Welding of Nylon 6A Using Taguchi and ANOVA with Microstructural Analysis

Friction stir welding is an environmentally friendly process of joining due to the nonusage flux, or any shield gas, and it does not produce harmful gases when compared fusion. Therefore, this article proposes experimental investigation optimization technique for studying FSW on nylon 6A polycaprolactam polymer composite plates. Specifically, influence input operating parameters such as tool rotational speed (TRS), feed rate, pitch values output response like ultimate tensile strength (UTS) hardness welded joints examined. In addition, L27 orthogonal array Taguchi approach employed design experiments parameters. The setup carried out with various parameter combinations 500 rpm, 1000 1500 rpm TRS, 30 mm, 40 50 mm rate by varying 1 2 3 mm. Further, analysis variance (ANOVA) also finding significant using regression equations. Finally, microstructural used assess mixing dispersing uniformity composites effectively.
