摘要
The mathematical model of temperature dynamics in the process of friction stir welding (FSW) is developed. The model allows to take into account changes in the input power and the temperature distribution in the sample during the FSW conversion of the welded material to the superplastic state and at the melting point. Temperature measurements were made at various points in the sample, and the power consumption of the motor of the milling machine was measured. This model is also used to estimate the linear velocity of the FSW, which is in satisfactory agreement with the experimental data. The model allows to establish the connection of the power consumption with the linear velocity of the FSW. (C) 2019 Elsevier Ltd. All rights reserved.
