Abstract
⺠Heat transfer and fluid flow in plasma arc welding are simulated and validated. ⺠A combined effective heat source model is proposed. ⺠Both heating and key-holing effects of the plasma arc are described in the model. ⺠Fluid flow shows contribution to the formation of hump in the weld-fusion line. ⺠Optimal process parameters could be obtained by using our model.
