Application of Creep Wave Inspection Technology
摘 要
对奥氏体不锈钢焊缝和异种金属焊缝表面及近表面缺陷进行爬波检测时, 缺陷的定位和定量(测长、测高)是爬波检测的难点。介绍了爬波检测技术的原理、爬波探头和试块。结合大量的试验数据, 总结了爬波检测技术应用的具体方法。包括检测系统的标定、灵敏度的设定、缺陷定位以及缺陷定量的详细方法。通过对检测技术的验证, 充分证明了爬波检测技术在奥氏体不锈钢焊缝和异种金属焊缝表面及近表面缺陷检测应用中的可靠性。
Abstract
The defect quantification and location is a problem during the creep wave inspection technology applying on the surface and subsurface of austenitic stainless steel weld and dissimilar metal weld. This paper introduces the theory of creep wave inspection, creep wave probes and blocks of several researching projects. And this paper summarizes the detail method of applying the creep wave inspection technology with integrating with much experimental data. The applying methods include adjusting inspection system, sensitivity setting , defect locating and sizing. The reliability of creep wave inspection technology applying on the surface and subsurface of austenitic stainless steel weld and dissimilar metal weld was testified with validating the technology.
