The evaluation of welding deformation on the vacuum vessel sector model of the Interaction Thermonuclear Experimental Reactor (ITER) has been performed using a finite element method analysis. The welding data of a simple plate test is translated to thermal shrinkage and applied to the model as an equivalent welding deformation force. The calculation results are compared with the results of full-scale mock-up test simulating on-site welding. As a result, the error of this analysis was obtained to be 10-25% in shrinkage and factor 5 in cross sectional deformation.
