| Abstract Scope |
In this study, COMSOL Multiphysics software was used to numerically simulate the temperature field during the friction stir welding (FSW) process of 2 mm thick 7075-T6 aluminum alloy. The simulated welding process was carried out at a constant welding speed of 100 mm/min, and the tool rotation speed was 500, 700, and 800 rpm. A finite element model including friction heating and plastic deformation was established to predict the transient temperature distribution. The simulation results were verified with the experimental data measured by thermocouples, and the results showed good agreement between the peak temperature and the thermal cycle. The results showed that higher rotation speed leads to increased friction heating, resulting in an increase in peak temperature. This study demonstrates the effectiveness of COMSOL in simulating the thermal behavior of FSW and provides a reference for studying the precipitation behavior during the FSW process of aluminum alloys. |
