符合ASME要求的承压设备焊缝超声相控阵检测（一）

摘要

结合国际权威法规ASME最新要求，研讨承压设备焊缝超声检测使用相控阵（PA）技术的重要条件和方法要领，突出该技术的工程应用实际和装置选项须知。旨在为国内承压设备推广应用PA技术、制定相应行业标准和刷新、升级UT人员的操作技能，提供有用借鉴。%Based on the latest requirements from the international authority ASME Code, the important conditions and technique essentials of ultrasonic inspection of pressure equipment welds using phased arrays (PA) are discussed, emphasizing the practical application in projects and the option items of apparatus and devices. The intention is to provide a useful reference for promoting the PA technology in NDE of pressure equipment at home, developing the related industrial standard and improving the technical ability of UT personnel.
