Abstract
A friction stir welding method with automatic adjustment of feed rate involves using a friction stir welding tool assembly to perform a friction stir welding process on two workpieces and the friction stir welding process includes using the friction stir welding tool assembly to perform friction stirring on the two workpieces along a welding path. The friction stir welding method is characterized in that during the friction stir welding process, the real-time feed rate of the friction stir welding tool assembly is determined by the following equation: FR p = FR o × ( 1 + ( D L × α ) ) .
