A smart, bi-directional model has been developed to determine three-dimensional temperature profiles, weld geometry and the transformed phase fraction during gas tungsten arc (GTA) butt welding. The model is capable of estimating input parameters such as the net input power, welding speed, effective thermal conductivity, and, activation energy… (More)
