A coupling model between arc plasma process and weld mechanics has been developed for the more accurate numerical analysis of weld distortion. Computational simulation of tungsten inert gas arc plasma based on mathematical modeling of the heat transfer from arc plasma to a welded plate is performed to obtain a more precise temperature distribution during welding. The temperature distribution obtained is used for a large-deformation thermal elastic-plastic stress analysis of weld distortion behavior. In addition, the effects of welding process conditions on weld distortion are examined considering molten pool configurations with the arc plasma process, and verified experimentally. Finally, the effectiveness of the weld distortion analysis by combining the arc plasma process with weld mechanics is evaluated.
