摘要
通过介绍动车变流器安装座焊缝涡流检测的灵敏度验证方法和验证过程,证明了在不脱漆状态下采用涡流方法检测焊缝疲劳缺陷的可行性,阐明了焊缝疲劳缺陷涡流检测的工艺要点。
In this paper,by introducing the sensitivity verification method and verification process of eddy current testing of the welds of EMU converter mounting seat,the feasibility of eddy current testing of weld fatigue defects without removing paint layer is proved,and the process essentials of eddy current testing of weld fatigue defects are pointed out.
