Abstract

In this paper experimental weld pools has been created in  axisymetric specimens of low carbon steel by autogeneous gas tungsten are (GTA). Different conditions of are current nozzle size and are tune have been investigated. The weld pool profile has been measured and plotted in each case. A numerical heat transfer model that takes into account fluid flow in the weld pool was employed to simulates the development of GTA welding process. The model has been tested against the experimental results to deduce the optimum values of are efficiency and heat distribution parameter. The model provides far better fit to the experimental results for the whole investigated range of parameters as compared to previous models. The degree of accuracy of the model is nor affected by the arc time within the investigated range The results have been discussed and interpreted.
