Three-dimensional transient thermo-elasto-plastic modeling of gas metal arc welding using the finite element method

As an initial step to three-dimensional thermo-elasto-plastic modeling of Gas Metal Arc Welding (GMAW), a three-dimensional finite element transient heat transfer model has been developed for the autogenous Gas Tungsten Arc Welding (GTAW) process which does not require the complicated metal transfer modeling. A mathematical model to calculate arc heat input when the welding torch is inclined at an angle with the vertical is presented and verified by comparing the numerically predicted size of fusion zone and heat-affected zone with experimental measurements. Effect of varying the shielding gas flow rate was also assessed and found to be negligible.
