Two-Dimensional Computation of Heat Transfer in Fusion Welding

Abstract

A two-dimensional finite difference model was developed to calculate the temperature distribution during the fusion welding process. The model is based upon the enthalpy formulation for phase change processes. Changes in thermal properties during the process have been accounted for. Temperature variations with respect to time have been calculated for specific locations in the cross-section of the work piece away from the edges for specified boundary conditions. These computations allow the estimation of cooling rates and the extent of the fusion zone. The model could be used in real-time monitoring of the welding process.
