The welding process of KTX vacuum vessel support was designed and then the distributions of welding temperature field and residual stress field were calculated through FE method. The strength of welding joints was assessed by a method combining the theoretical analysis and FE analysis. The analysis results verified the reliability of the welding structure and provided theoretical basis for the welding process of vacuum vessel support structures. 相似文献

Thermal diffusivity of reduced activation ferritic/martensitic (RAFM) steel CLF-1 has been determined by the modified photoacoustic piezoelectric (PAPE) technique. Firstly, the modified PAPE theoretical model is introduced and the experimental condition with high measurement precision are identified; Secondly, the experimental system is set up and calibrated by investigating the thermal diffusivity of nickel; Finally, the thermal diffusivity of RAFM steel CLF-1 is measured by the modified PAPE method. The results show that the RAFM steel CLF-1 has good thermal diffusion properties and is a fusion reactor structural material with excellent heat conductivity. The modified PAPE technique can determine the thermal diffusivity of RAFM steel CLF-1effectively, and provides an effective way to investigate the thermal-physical property of fusion reactor structural material. 相似文献
