TOFD检测是一门新的无损检测技术,由于该技术在发展阶段,所以大多数的研究集中在适用范围和新设备开发方面。对于操作的规范性以及操作的方法技巧等关注很少。尤其对因为不正确的操作对检查结果会造成什么样的影响,国内外文献更是很少看到。本文从检测过程中最容易出现的中心线偏离问题入手,从理论上探讨其对检测结果的影响。让操作人员明白,正确操作的重要性,以及误操作的危害。增加其对操作规程的重视程度,以便取得更精确的检测结果。
TOFD testing is a new non-destructive testing technology. As the technology is in its development stage, most of the research focuses on the application scope and new equipment development. Little attention has been given to the normative nature of the operation and the methodological skills of the operation. In particular, due to incorrect operation of the test results will cause what kind of impact, domestic and foreign literature is seldom seen. In this paper, the most prone to center line departure from the detection process to start with, theoretically explore the impact on the test results. Let the operator understand the importance of correct operation, as well as the dangers of misuse. Increase its emphasis on the operating procedures, in order to obtain more accurate test results.
