摘要
本文分析了相控阵超声检测对缺陷定量的特点,介绍了相控阵超声采用工程临界分析法(ECA)对缺陷定量的特殊性.通过多种检测方法对焊缝中预制缺陷进行检测和分析,发现采用工程临界分析法定量不仅能合理地分析评定缺陷,还能保证检测结果一致.得出相控阵超声检测采用工程临界分析法对缺陷定量既科学合理,又准确可靠.
Abstract
This paper analyzes the characteristics of phased array ultrasonic testing for defect quantification,and introduces the particularity of phased array ultrasonic testing using engineering critical assessment(ECA)for defect quantification.Through a variety of detection methods to detect and analyze the embedded defects in the weld,it is found that the engineering critical assessment method can not only rationally analyze and evaluate the defects,but also ensure the consistency of the test results.It is concluded that the method of engineering critical assessment in phased array ultrasonic testing is scientific,reasonable,accurate and reliable.
