某三代核电蒸汽发生器水室分隔板防焊接变形质量监督

Quality Supervision of Anti Welding Deformation of Water Chamber Partition Plate of Steam Generator in A Third-generation Nuclear Station

蒸汽发生器(steam generator,SG)水室分隔板的焊接变形控制一直是装焊工序的重点和难点。针对某三代核电项目的水室隔板的焊接,收集借鉴了CPR1000项目SG水室分隔板的焊接工艺和防变形措施,制定了该三代核电项目SG分隔板的防变形工艺方案和风险防范点,并进行了防变形措施的落实跟踪,最终装焊质量一次合格。

The welding deformation control of water chamber partition plate of steam generator has been the key and difficult point of the welding process. According to the welding of water chamber partition plate of a third-generation project, the welding process and anti deformation measures of SG water chamber partition plate of CPR1000 project were collected and used, and the anti deformation technology and risk prevention point of SG partition board of the third-generation project were worked out. The implementation and track of anti deformation measures were carried out. Finally, the welding quality was qualified at one time.
