摘要
The weld penetration extent was described by 3D information on the surface depression of full-penetrated weldpool. According to a developed model for transient behaviors of tungsten-inert-gas arc weldpool, the dynamic evolution process of surface depression of full-penetrated weldpool in quasi-steady state after changing welding process parameters is numerically simulated, and the basic data obtained can be used in designing weld penetration control system. The welding experiment showed that the predicted surface depressions for both top and bottom sides of weldpool are in agreement with the measured ones.
