Influence of temperature of friction stir welding process with mixing FSW on the strength of the weld

Abstract

The use of heating leads to reducing plastic deformations of thin sheets welded by the FSW method. Preheating increases the process temperature and allows higher feed rates to be used, thus reducing the time of the proc- ess. Tests made on connections with the same parameters showed much higher tensile strength in the case of using heating. Thermal imaging studies have shown the heat dissipation process and it has been noticed that the initial temperature is significantly lower, which undoubtedly results in the formation of a lower strength weld.
