A mathematical model of temperature distribution in the process of friction stir welding (FSC) of a homogeneous massive body has been developed. The model makes it possible to take into account the geometric dimensions of the tool, the thermophysical properties and the temperature distribution in the sample during the transition of the welded material into the superplastic state. The paper presents comparisons of the temperature distribution of homogeneous thin-sheet and bulky samples. Measurements temperature were carried out at various points of the hemispherical sample during the FSW process. This model is used to estimate the linear velocity of the FSW associated with the thermophysical properties of materials. The calculation results are in satisfactory agreement with the experimental data.
