The friction stir welding technique is predominantly considered to be one of the most promising welding techniques in the last decade. With regard to Al-alloys, unweldable by traditional welding processes, friction stir welding is currently more common with a significant degree of acceptability for industrial applications. Undoubtedly, the ideal control of the variables of friction stir welding processes leads to a significant improvement in the mechanical properties of the welded joints. Thus, it is of interest to achieve the optimal conditions of the friction stir welding process. The aim of this study is to optimize the process conditions of the optimum dissimilar aluminum alloys (AA6061 and AA7075) friction stir welding in terms of mechanical properties (UTS, ductility, hardness, and Impact strength) using Fuzzy AHP-TOPSIS-based Taguchi Approach. In order to find the optimal conditions, the Taguchi orthogonal array L9, designed by considering three levels of process parameters (rotational speed, traverse speed, and axial force) was utilized. The results of the application of the fuzzy AHP-TOPSIS method showed that the conditions of friction stir welded process (traverse speed 25 mm/min, rotational speed 1400 r/min, and Axial force 6 kN) exhibited the maximum mechanical properties: UTS of 91 Mpa, ductility of 7.5%, Brinell Hardness (HB) of 91.3, and impact strength of 8 J.
