A detailed analysis and refinement of a method of numerically modeling deep-penetration welding processes using geometric constraints based on boundary information obtained experimentally is presented. The general features of the numerical method have been described previously. This paper considers issues concerning accurate numerical calculation of temperature and velocity fields in regions of the melt pool where the flow of fluid is characterized by quasi-stationary Stokes flow. It is this region of the melt pool that is closest to the heat-affected zone and that represents a significant fraction of the fusion zone.
