Proficiency Testing Scheme and Technical Analysis of Ultrasonic Testing of Welding Joints in Steel Structure
-
摘要: 介绍了由第三方机构组织的建筑钢结构焊缝超声波检测能力验证计划。该计划测试了92家检测机构对相同检测样品进行超声波检测的结果,然后基于稳健统计技术与Z比分数,对检测数据进行了技术分析。最后讨论了影响检测结果的因素。Abstract: A proficiency testing scheme of ultrasonic testing of welding joints in steel structure organized by a third part unit has been introduced. A Z-score testing procedure was applied to evaluate the 92 pieces of PT samples, with the investigation of influence factors on the results as well.
