Abstract : A three dimensional transient Finite Element Model (FEM) of Flux assisted Gas Tungsten Arc Welding (F-GTAW) to predict the temperature cycle at the weld lineof Duplex Stainless Steel (DSS2205) is proposed in this study using gaussian moving source. Theproposed finite element model is validated using theexperimental results published in the literature. The temperature history plot obtained from the FEM is compared with the experimental data. The results shows that the peak temperature value at a surface node of the FEM is matching with the maximum temperature obtained at the surface of the weld. The proposedmodel has the capability to predict the temperature history of the entire welding cycle. The temperature distribution profile obtained from the FEM of F-GTAW is also compared with the conventional GTAW model. The proposed FEM model has been developed using Ansys software.
