摘要
本文应用超声波探伤原理,对表面开口人工窄缝缺陷和实际疲劳裂纹缺陷的深度,进行了超声检测、对比和分析,给出了基准灵敏度确定原则和实用超声检测方法。
Based on the theory of ultrasonic flaw deletion, this article contrasts and amalyses the results of inspection and measusement of the flaws, such as cracks on metal surface,artificial cracks.in metal and the cracks caused by fatigue.This article puts farward the principles used to determine the sensitivity of inspection and measurement and the practical methods of inpection and measurement.
