Abstract

Abstract

For the excessive radial deformation problem of the reactor pressure vessel during the welding process, based on SYSWELD, the numerical simulation analysis of the multi-pass welding of a main pipe is conducted, and the effects of three sub-sectional welding schemes on the welding residual stresses and welding deformation are investigated. The results show that, the numerical results are in good agreements in the experimental data, so the numerical approach involved is validated. The sub-sectional schemes can effectively reduce the radial displacements of the pressure vessel main pipe during the welding process. Among the three welding schemes, the sub-sectional up-to-down single-side scheme shows the best effect on the welding radial deformation suppression.
- Main pipe,
- Multi-layer and multi-pass welding,
