Description
Summary:The results of friction-stirring welding with stirring are presented on the example of the aluminum alloy AMg-5. The technological process on the experimental installation is briefly described. Defects arising in the process of friction stirring welding are assessed. Main stages of friction welding technological process are singled out. In the course of researches it is established that during the process the tool rotation speed and feed speed are combined in such a way that an asymmetric metal flow is obtained. Welding parameters and the size of the tool in the FSW process have a decisive influence on the total torque, which determines the need for clamping equipment and tool lifecycle. It is shown that the total torque and torque components from different parts of the tool at different welding parameters and size of the tool change slightly depending on the welding speed, but the total torque remains constant.
