小直径棒材和板材的水浸探伤研究

Study of water immersion test for bar with smaller diameter and plate

主要介绍了利用超声波水浸探伤法对板材和小直径棒料进行探伤的原理及应用,并着重的讨论了超声波水浸法探伤的特点及水浸法探伤与接触法探伤的区别,论述了应用水浸法对板材和小直径棒料进行探伤时,可弥补使用接触法探伤时对近表面缺陷的检出能力方面的某些不足。

The paper introduces the principle and application of ultrasonic water immersion test for bar with Smaller diameter and plate, particularly discusses the characteristics of uhrasonic water immersion test and difference in comparison with contact test. Herein it is proved that the water immersion test can cover the Shortage Caused by contact test.
