摘要

An analytical model for estimation of fluid flow behaviour in various sizes of gas metal arc welding torch nozzle under different shielding gas and inlet Gas Flow Rate (GFR) has been worked out. The variation in fluid flow behaviour with a change in gas flow" rate and shielding gas has been satisfactorily analysed. To verify the model, surface appearance of weld deposit has been studied under different GFR at a given shielding gas during weld bead on plate deposition on plain low carbon steel. The theoretical model may provide wider opportunity to design the different GMAW torch nozzle for welding of various plate thicknesses and groove design.
