超声相控阵检测（PAUT）的可靠性取决于检测工艺，各个船级社针对此技术都提出了工艺认可的要求。相控阵检测工艺认可是相控阵应用的必要手段，通过认可过程，能让相关方了解相控阵的优缺点，对相控阵的推广极为有利。对检测技术进行工艺认可的方案及实施步骤，有助于相关检测人员了解海洋工程企业的无损检测特点。

The reliability of phased array ultrasonic testing (PAUT) depends on the testing procedure, and almost all the ship classification societies have required that this technology be procedure qualified because the qualification is necessary for the effective application of the PAUT. Through the qualification process, the related applicants can understand the advantages and shortcomings of the PAUT, which is very helpful for the popularization of the technique. The concrete schemes and steps are introduced in the paper to benefit related NDT personnel to understand the characteristics of NDT in offshore engineering enterprises.
