EN: The main components of friction stir welding process of an aluminum-based alloy (AMg6) are considered. As a result of passage working tool along of connecting edges, formation a temperature gradient on their thickness determines development processes of structural changes. Based on this, in different layers of the weld, in accordance with the heating temperature, a different degree of plasticization alloy is achieved. Separate structural zones of the welded joint and their influence on the value of hardness are considered. The observed asymmetry of the weld is determined by the direction of rotation working surfaces of the tool. Based on the analysis of results of studies for the AMg6 alloy, an explanation is proposed for the formation gradient structures in the weld zone during friction stir welding.
