Abstract: Computational model is established for analysis of 3D welding temperature field caused by moving welding arc, in the model the concept of enthalpy and surface double ellipse distribution heat source are adopted. Relevant software is compiled for the model, which possesses higher precision. The model is employed to analyze TIG welding temperature field to obtain the shape and size of welding pool and temperature distribution in HAZ. It shows that the agreement is well between computational result and experiment result.

Key words: Numerical simulation, Temperature field, TIG welding
