Optimizing Rotational and Travel Speeds in Friction Stir Welding of Aa7050-T7451 and Aa5083-H116: An Enhanced Analytical Model

Abstract

The mathematical modeling of friction stir welding is beneficial because of the deep insights that the model provides into the effect of process parameters on the trend of response outcomes. Therefore, this study aims to provide an analytical solution for the friction stir welding (FSW) of AA7075-T7151, AA5083-H116, and AA7075-T7151-AA5083-H116 dissimilar joints. The developed model is neces-sary to optimize tool rotational speed (TRS) and welding speeds (WS). The optimum welding parameters have been estimated based on a developed analytical model, which has been used to obtain a feasible window of optimum tool rotational speeds and welding speeds. Among these obtained parameters, the chosen tool rotational speeds are 279, 309, 334,351, and 376 rpm, and welding speeds are 90, 93, 97, 99, and 102 mm/min, respectively.
