OBJECTIVE Abstract - Friction stir welded Polypropylene & Al6061 plates with a thickness of 3 mm using welding settings (weld speed and rotational speed). The trials were planned using the Taguchi design of experiment approach. An increasingly common technique, friction welding (FW) is a set of solid state joining methods based on friction that may produce highquality welds of different components comprised of similar or different materials. The input parameter choosen rotational speed & welding speed And Output Parameter is Tensile strength. The Taguchi technique recommended allocating the factors selected for the experiment using an orthogonal array design. Using the Taguchi method's L9 orthogonal array, nine experiments have been constructed. The signal-to-noise (S/N) ratio and analysis of variance (ANOVA) have been used to examine and optimise the welding settings. Following examination, the most important control factor for tensile strength is identified.

1. INTRODUCTION The process of joining metals by means of heat and pressure is known as welding. Welding is a construction or artistic technique that, unlike brazing and soldering, which do not melt the base metal, creates fusion between materials, most commonly metals or thermoplastics. It is common practice to augment the base metal with a filler material before welding the two together. This creates a pool of molten material, called the weld pool, which, when cooled, forms a junction that is just as strong as the base metal itself. A weld can be formed using either heat or pressure alone or both. Several different types of energy can be used to conduct welding processes. These include gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. The outdoors, underwater, and even space are all viable locations for welding. The hazards of welding include the possibility of burns, electric shock, eye injury, exposure to harmful gases and fumes, and intense UV radiation. One kind of friction welding, FRICTION STIR WELDING, will be the primary topic of discussion as we go over the study's classification of welding processes and their uses.

3.2 Objective of Taguchi Method To improve process and product design, Taguchi is looking for easily controllable factors and their settings that reduce product response variability while maintaining a desired mean response. By adjusting those parameters to their sweet spots, we may make the product more resistant to variations in both operating and environmental circumstances. Removing the bed effect rather than the cause of the bed effect allows for more stable and high-quality goods to be obtained during the Taguchi parameter design stage. In addition, the method can save money and eliminate wasted goods by systematically applying it at the pre-production stage (off line), which means fewer tests are needed to determine cost-effective process conditions.
