Abstract:- The effects of the sign of the surface tension coefficient on turbulent weld pool convection are studied for a typical Gas Tungsten Arc Welding (GTAW) process. Three-dimensional turbulent weld-pool convection in a pool is simulated using a suitably modified high Reynolds number ε−k model in order to account for the morphology of solid-liquid interface and the phase change aspect of the problem. Key effects regarding the sign of surface tension coefficient in the turbulent transport in a GTAW process are highlighted by comparing the turbulent simulation results with the corresponding ones from a laminar model, keeping all process parameters unaltered.
