摘要
介绍了基于全矩阵数据采集(FMC)的全聚焦(TFM)3D相控阵超声检测技术,并给出了用其检测大口径厚壁奥氏体不锈钢管道焊接接头的实例,可望为3D全聚焦相控阵超声检测的相关应用提供借鉴。
The total focusing method(TFM) 3 D phased array ultrasonic testing technology based on full matrix capture(FMC) is introduced, and some examples of its application for the detection of welded joints of large diameter thick-walled austenitic stainless steel pipes are given, which is expected to provide reference for the related application of 3 D full focus phased array ultrasonic testing.
