摘要: 以大口径长输油气管道的全自动超声波检测（AUT）为例，介绍了AUT试块的设计思路及试块中各人工反射体的作用，说明了AUT试块的加工、检验及AUT试块检测验证的质量控制程序，为使用该试块的检测人员提供参考。Abstract: This article is to take the automatic ultrasonic testing of large diameter and long distance oil and gas transportation pipeline (AUT) as an example and to introduce the design method of the testing blocks. It also shows the related functions of the artificial reflectors in the blocks. The quality control measures in manufacturing and testing of AUT testing blocks are outlined. It can provide reference for testing personnel who use block.
