对于表面裂纹深度的测定,通常采用超声波探伤法和直流电位法。本文主要对目前常用的几种主要超探方法进行研究探讨和比较,确定一种较适宜的方法、以满足在役压力容器安全评定无损检测的需要。
For the determination of the depth of surface cracks, usually ultrasonic testing and DC potential method. In this paper, several commonly used major methods of ultra-exploration are discussed and compared to determine a more appropriate method to meet the needs of non-destructive testing of in-service pressure vessel safety assessment.
