摘要
介绍焊缝相控阵超声检测(PAUT)最新国际标准ISO/DIS 13588:2010,该标准适用于半自动或全自动UT。重点内容:(1)检测等级;(2)试块制备;(3)设备校验;(4)工艺评定;(5)方法要领;(6)数据分析。强调扫查设置图(PS)的重要性和关键参数。意在通过比照ISO和ASTM、ASME相似标准,为国内制定自己的PAUT标准,提供借鉴。
This article introduces the latest international standard ISO/DIS 13588:2010 related to in- spection of welds by using ultrasonic phased array (PAUT)technology through automated or semi--auto- mated manner. The key points are comprised of (1) Testing levels; (2) Preparation for reference blocks ; (3)Equipment calibration; (4)Procedure qualification; (5) Method essentials; (6)Data analyses and evalu- ation. It emphasises the importance of Scan planning and its key parameters. The intention is to provide useful reference for comparing this ISO PAUT standard with the recent similar ones of ASTM and ASME and establishing national PAUT standard soon.
