Analysis of Defect Height Test with UT in Weld Inspection
-
摘要: 焊缝超声检测时,一般根据缺陷回波高度及长度进行评判。然而,在海洋工程部分项目的特殊要求中,需要对缺陷回波高度、缺陷长度及缺陷高度进行综合评判。笔者对美国标准中推荐的几种缺陷高度测量方法进行了介绍,并分析其适用条件和精确性,为无损检测同行提供参考。Abstract: Weld is normally evaluated with defect length and echo height in UT inspection. However, it is requested that evaluation shall be carried out considering echo height, defect length and defect height, because of special requirement in part of offshore project. This paper will introduce the height test methods recommended in American standard, and analyze the applicability and accuracy. It will also provide reference for NDT colleague.
