- 摘要:
- 根据全自动超声波检测(AUT)评判的基本原理和实践经验,结合实际检测得到的西气东输二线工程中管道焊缝AUT的扫查图,按照焊缝的坡口分区,依次介绍了根部、钝边、热焊及填充层等各个区域缺陷在扫查图中的表现特点及对其定性定量的评判方法。
Based on the fundamental principle of automated ultrasonic testing (AUT) and practical experience,together with the AUT scan maps from practical tests for the Second West to East Gas Pipeline Project,this paper illustrates in turn the defect performance features of roots,blunt edge,thermal welding and filling layer in groove position as well as their quantitative evaluation methods.2010,4(4): 60-62 收稿日期:2009-6-8分类号:TE973.3作者简介:房金库(1972-),男,河北武强人,工程师,1996年毕业于中国石油大学,现从事无损检测工作。
