抄録	The objective of this research is to develop a practically useful finite element method for predicting distortions of structures under welding assembly. In this method, distortions produced by various thermal processes, such as the cutting, the forming, the welding and the straightening can be considered. These distortions are simulated using the inherent strain. On the other hand, the detail of how the gaps and the misalignments are controlled during the fitting process also has significant influence on the distortion. The gaps and the misalignments between parts are modeled using the interface element. The potential capability of the proposed method is demonstrated through simple examples.
