Friction Stir Welding (FSW) is a modern technology employed in welding aluminum alloys in various industrial fields such as airplane industries. Therefore, AA 2024-T3 alloy can be one of the active materials used in this field. From here, numerous studies have been conducted on the natural flow of air and water to cool the welded joints of this alloy. Nonetheless, the forced air and water were not utilized with this alloy. Hence, the purpose of this study is to apply these forced convection mechanisms to specify the optimal outputs of tensile functions using multi-objective optimization by the General Full Factorial (GFF) technique. In addition, the rotational speeds were 800, 1000, 1200 rpm in this experimental medium. Therefore, the optimal parameters resulting from this work were 1200 rpm and forced water to achieve the best performance. Furthermore, the morphology of the fracture region is induced by these parameters leading to appearing big dimples. Finally, these dimples contribute to enhancing the plastic fracture without brittleness.
