ASME、RCC-M和JB/T4730关于焊缝射线检测规定的对比分析

Comparison and Analysis of RT for Welding Subject to ASME,RCC-M and JB/T4730

ASME、RCC-M和JB/T4730是目前国内广泛采用的标准,各标准既互相借鉴又互有差异,本文从胶片、IQI、检测技术、射线源和几何不清晰度等几个要素入手,对比分析了ASME、RCC-M和JB/T4730关于焊缝射线检测的差异,为相关从业人员正确运用各标准提供借鉴。

ASME, RCC-M and JB/T4730 are widely used in China. They are similar specifications with differen ces one aother. This paper compares and analyzes the differences, mainly focusing on film, IQI, techniques, radioactive source and geometrical unsharpness, etc., in order to share with others for correct use of the specifications.
