Abstract
Summary This paper describes a three-dimensional model for circumferential GTA welding of pipes with a single V groove. It consists of a heat conduction model and a molten pool balance model. In the heat conduction model, the transient temperature distribution on the pipe is numerically analysed to estimate the molten pool size by the finite difference method. In the molten pool balance model, the theoretical configuration of the molten pool is calculated using the molten pool size derived from the heat conduction model with regard for the balance of gravity, the surface tension and the arc pressure. These models are used to examine the effects of various welding parameters, such as welding positions and joint geometries, as well as the effect of the arc pressure on the welding process. The results suggest that the proposed numerical model is suitable for estimation of welding process parameters during groove welding of pipes.
