小径管对接焊缝超声波探伤规程、导则的应用及缺陷波的识别

摘要

Combining with the practical experience, this article gave the comparative analysis of the small diameter tube related ultrasonic testing guides and the rules, and discussed the wave identification features of ultrasonic testing of the small diameter tubes. Through the analysis and comparison, this article gave the suggestion on application of different thicknesses of small diameter tubes ultrasonic testing guides and rules.%结合多年实践，对小径管对接焊缝超声波探伤相关规程、导则主要异同及其对缺陷判伤影响进行了分析，并对缺陷波的识别进行了论述，对不同壁厚的小径管超声波探伤如何执行规程和导则给出了建议。
