Chromel-alumel thermocouples were used to study the temperature state of 10 mm copper plates at simulation of the process of friction stir welding. Thermocouples were welded on in blind holes located along the line of welding tool displacement that allowed recording the copper temperature at the moment of weld formation under different welding conditions. In the studied range of variation of process parameters, the metal temperature is mainly influenced by the area of interaction of the welding tool working surface with the plate, while the speed of tool rotation has a minor effect. At the moment of weld formation the metal temperature varied from 528 up to 980 in different modes. 13 Ref., 3 Tabl., 3 Fig.
