摘要
围绕 K值展开讨论 ,提出一种符合现行标准、规程要求的标准椭圆封头拼接焊缝的射线探伤工艺。使用这种方法 ,一般只需两到四次透照就能完成封头焊缝的探伤。
By a discussion on K value, the radiographic technology for the butt welds in standard elliptic sealing heads consistent with current standards and regulations is presented. It takes only two to four irradiations to inspect a sealing head weld by using the technology.
