It considers the deformation of molten pool surface at the condition of full-penetrated workpieces, takes the arc pressure as the driving force of weld pool surface depression, and determines the surface configuration of weld pool based on the dynamic balance of weld pool gravity, arc pressure and surface tension. The fluid flow and temperature fields in weld pools of stainless steel workpieces are analyzed by using SIMPLER algorithm. TIG welding experiments are made to verify the validity of the model. It shows that the predicted results by the model are in good agreement with experimental ones.
