Abstract

In order to study the temperature field (TF) distribution and material flow (MF) in the friction stir welding process, the finite element model of friction stir welding (FSW) was established to simulate the welding process. The temperature field results showed that the temperature on the advancing side (AS) was higher than the retreating side (RS). The temperature field has an important influence on the material flow, so the material flow in the plunging stage and welding stage is simulated numerically to study the material flow trajectory in different stages. The results show that the material distribution is more uniform due to the long time in the plunging stage, and the amount of material flow in the plunging stage is larger than that in the welding stage. In the welding stage, it is found that the shoulder can promote the material flow. After analyzing the displacement of tracking particles in the welding stage, it is found that the displacement of particles on the AS is significantly higher than that on the axis and the RS.
