Welding distortion not only negatively affects the dimensional accuracy but also significantly degrades the quality and performance. Although many researchers and engineers have made great efforts to control and reduce welding deformation, it is still a difficult engineering problem. In the current study, welding distortion in a large thin-plate panel structure was predicted by means of elastic FEM based on inherent strain theory and interface element formulation. The welding distortions in the thin-plate model computed by large deformation theory and by small deformation theory were compared. In addition, the influences of welding procedure and assembly sequence on the final distortion were examined numerically.
