摘要：

On basis of the finite element software DEFORM,the 2D coupled thermo-mechanical model of continuous drive friction welding of ring parts is established.The temperature and the flashes during the welding process are investigated.The results of numerical simulation show that the temperature of friction surface is higher than that of other region and the peak temperature increases with the increase of welding time.During the process of friction stage,no flash appears because of the low temperature and the small axial friction pressure.At the forging stage,the flashes appear,whose dimensions and bending degree increase with the increase of welding temperature.Moreover,with the increase of rotational velocity and axial forging pressure,the dimensions and the bending degree of flashes of continuous drive friction welding increase.
