双金属格架电子束焊接的质量控制
|
摘要
双金属格架是压水堆核燃料的重要组成零件,属于核反应堆芯产品,其产品质量对核电安全具有重要的意义。电子束焊接是双金属格架制造的关键工艺,多年来通过生产摸索出很多的质量保证措施,但一直未形成系统化。根据国家标准《焊接质量保证一般原则(GB/T 12467-90)》及行业标准《压水堆核电站燃料组件设计和建造规则(RCC-C 2015)》中对焊接质量控制要素的规定,从原材料管理、技术管理、生产现场、焊接缺陷、产品检查与文件控制等方面对此进行探讨,形成标准化、系统化的焊接质量控制方法。以实现提高最终产品质量,提升用户满意度的目的。
The bimetal grid is a major component of nuclear fuel assembly,which belongs to nuclear reactor core product. So the welding quality of Bimetal Grid is of great significance for the nuclear power safety. The electron beam welding process of the bimetal grid is gradually applied to parts manufacturing of PWR nuclear fuel. Because there are many factors affecting the process,so there are many quality assurance measures. Over the years,these scattered quality control methods have not been systematized. According to the stipulation of quality control elements in GB/T 12467-90 and RCC-C 2015,combining with the experience and methods in the supervision of company's production and quality management summarized over the years,discussions are made on material control,technology management,production site management,welding defects control,product inspection,document control,etc. Finally,a standardized and systematic welding quality control method is developed. In this way,the final product quality and the user satisfaction can be improved.
