%X A three dimensional transient finite element model with Gaussian heat source was proposed to predict the heat transfer in Gas Tungsten Arc Welding (GTAW) of stainless steel 304 and experimental tests were conducted to study chromium carbide precipitation and to verify the developed model. The position of chromium carbide precipitation band and its relation to welding parameters were studied. The results showed, increasing the heat input of weld, increases the distance in which precipitation in austenite grain boundaries occurs. After measurement of carbide-band distance from weld centre and using obtained time-temperature curves of the developed model, the distance of carbide-band from the weld centre line was simulated. Finally, good agreement was observed between experimental and simulation results in terms of prediction of thermal history and carbide precipitation.
