Notes:
Heat generation is a dynamic process under solid state joining conditions during frictionstir welding (FSW). In this article, a new heat source model in which heat generation, depending onyield stress and tool rotation speed, was established and was applied to simulate thermal field ofFSW welded 2024-T3 panels. Results showed that for 2mm/s welding speed and 400rpm rotationspeed, the simulated temperature-time curves on different positions corresponded well withmeasured results. With the increasing of rotation speed, temperature increased steadily but tended toa saturation state at high rotation speeds, which is consistent with the fundamentals of solid statejoining
