Abstract

A two-dimensional mathematical model was developed to calculate the temperature distribution during welding of thin tantalum sheets. The solution of the unsteady heat flow equation was obtained employing a computer program based on the finite difference method. The model does not require any assumptions regarding the shape of the welding pool. Arc parameters, radiative and convective heat losses and the dependence of the relevant physical properties on temperature are taken into account. The shape of the welding pool and isotherms are calculated and compared to experimental results.
