Abstract

Friction stir welding (FSW) as a solid-state joining method has been applied to the Al-Cu dissimilar joint. However, most research has focused on the technical study of FSW and little attention has been paid to the investigation of the heat source. This paper aims to develop a numerical thermomechanical model for Al-Cu dissimilar FSW process. The model results show that the calculated temperature values are closely correlated with the experimental temperature value, ensuring the accuracy of the model. Furthermore, the model is used to analyze the characteristics of the dissimilar FSW temperature field. It is observed that the temperature field was asymmetrical, which was caused by the different properties of the materials and the different heat inputs in the welding process. Moreover, the variation in the temperature field decreases with the increase in the offset.
