Friction Stir Welding (FSW) is a solid state welding process widely used for joining of similar and dissimilar metals for various engineering applications. AA2024 AND AA6061 plates of 6mm thickness were joined by using non-consumable tapered (semi-conical) twin pin tool. The wedding parameters considered for this study are tool rotational speed, welding speed and tool tilt angle at three levels, experiments were conducted as per Taguchi's L27 orthogonal array. By varying welding parameters defect free welding joints were produced later ANOVA analysis was carried out to investigate the percentage of contribution of parameters to improve the mechanical properties.
