摘要：

Friction stir welding (FSW) is a solid-phase welding method. Weld forming and welding quality are related to the heat generated by plastic flow in FSW process. Therefore, it is of great significance to realize the measurement of the viscoplastic heat generated in FSW process. In this paper, based on the working principle of rotary viscometer, the calculation model for the viscoplastic heat in friction stir welding was proposed. The validity of the calculation model was verified by simulation experiment. The correctness of the calculation model was verified by friction stir welding experiment.
