Through employing the developed model for transient behaviors of tungsten-inert-gas arc weldpool, the dynamic transformation process of surface depression of full-penetrated weldpool after a sudden variation of welding process parameters in quasi-steady state is numerically simulated, and basic data are obtained to guide designing weld penetration control system. The welding experiment results show that the predicted surface depression for both top and bottom sides of weldpool is in agreement with the measured one.
