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