结合工程实践,针对标准对检测仪器与探头性能要求的差异、锻件检测标准应用、支管角焊缝斜射波可检区域、各阶段对焊接接头附近母材检测要求的差异、超声波测厚等问题进行探讨,并提出建议措施,为核岛主设备超声检测标准的制定和设计提供参考。

In this paper, combined with engineering practice, the differences of standards on the performance requirements of examination apparatus and probes, the application of forging examination standards, the shear wave scanning area of fillet weld of branch pipe, the difference of base metal detection requirements near welded joints at different stages, and ultrasonic thickness measurement were analyzed and discussed,and the suggestions were put forward. The object of this paper is to provide reference for establishing standard and design of the ultrasonic testing for nuclear island primary components.
