An analytical model for estimation of heat flow behaviour in gas metal arc welding torch nozzle and contact tip have been worked out. The variation in heat flow behaviour under different locations has been satisfactorily analysed. The theoretical model may provide wider opportunity to design different GMAW torch nozzle for welding of various plate thicknesses and groove design.
