Influence of water layer thickness on sensitivity of water immersionultrasonic testing for pipeline welds
摘 要
在水浸超声检测中,水层厚度直接影响检测的灵敏度和缺陷检出率。实际应用中,扫查装置的安装误差会导致水层厚度产生偏差。通过测量不同水层厚度下的探头检测灵敏度,得出水层厚度偏差对检测灵敏度的影响规律,可为同行提供参考。
Abstract
In water immersion ultrasonic testing, the thickness of the water layer directly affects the sensitivity and defect detection rate. In practical applications, the installation error of the scanning device will cause deviations in the thickness of the water layer. By measuring the detection sensitivity of probes under different water layer thicknesses, the law of the influence of water layer thickness deviation on detection sensitivity is obtained, which can provide a reference for the peers.
