In this paper,the finite element method(FEM)is used to analyze the post-weld dehydrogenation induction heating process for the surfacing of tube sheet on its primary side of a nuclear power evaporator. The inductor structure suitable for induction heating of tubesheet was designed. The electromagnetic-thermal coupling model of tube-sheet induction heating was established based on the ADSL program in ANSYS. The influences of the structure and parameters of induction coil on the temperature distribution during induction heating were studied. The results showed that under the suitable parameters,the installation of induction coils on both sides and bottom could greatly improve the overall heating effect and heating efficiency. Experiments of the optimal parameters were carried out and the simulated temperature distribution was agreed with the experimental results.
