Abstract

This study describes the creation of permanent joints in a high-strength aluminum alloy using friction stir welding. The strength of the welded joint was achieved at the level of the base metal strength by using an active liquid cooling system and subsequent aging of the alloy. The influence of liquid cooling intensity on the structure and mechanical properties of the joints was also revealed. Welding parameters were developed to form full strength weld.
