摘要
TOFD自动超声检测技术在国内得到越来越多的应用,它以缺陷检出率高和精确定量的优点而被人们所接受,在很多领域都能代替射线检测,特别是一些大型的超限设备,TOFD应用很广泛。简单介绍了TOFD自动超声检测的原理,用具体的实例阐述TOFD在实际检测中的应用。
TOFD based automatic ultrasonic inspection has got more and more applications in China. It has the advantage of high fault relevance ratio and accurate quantitative, and can substitute radiographic inspection in many fields, especially in some super large equipment. In this paper, the theorem of TOFD based automatic ultrasonic inspection method was introduced. As a case of study, an instance from a real metal inspection application was expatiated.
