| 摘 要： | 由于ASG管嘴焊缝结构的复杂性,为优化其无损检测方法,改进超声波检测工艺,按照RCC-M规范要求,设计了全尺寸0°和90°ASG管嘴焊缝对比试块。通过理论分析和采用多角度探头的试验验证,确定35°和45°探头的组合可以覆盖整个焊缝的厚度范围,能有效检测出试块上的人工缺陷,且满足RCC-M标准要求。在超声波检测试验基础上,制定出了具有针对性的检测工艺。

| Abstract: | As ASG nozzle welding structure is complex,in order to optimize it＇s nondestructive testing,the ultrasonic testing（UT） procedures.The paper desiged whole-size ASG contrastive block（0°and 90°profile） according to RCC-M.The paper also used theoretical analysis and diverse angle probes verification,and got the conclusion that probes with refraction angle of 35°and 45°could cover the whole range of the welding thickness,and find artificial defects on the contrastive block.The result meets RCC-M requirements.In the end,the paper establishes pertinent nondestructive testing procedures according to test result. |
