超声编码相控阵的应用

Applications of Ultrasonic Encoded Phased Arrays

介绍超声编码相控阵的技术特性和典型应用,包括腐蚀检测、小径管检测、大径管检测、管道自动检测和钢厂在线检测等,意在为国内承压设备焊缝无损检测,推广符合国际法规要求的半自动或全自动超声相控阵技术,提供有用借鉴。

This article described technical characteristics and applications of ultrasonic encoded phased array, including corrosion mapping, small diameter pipe inspection, large diameter pipes, pipeline AUT, in-line inspection systems （pipe mills）, etc. The intention is to provide useful references to promoting fur- ther the use of auto- or semi-auto PAUT technology at home, meeting the requirements Of the recent inter- national code and standards.
