摘要
文章针对铁轨部件裂纹缺陷及焊缝质量检测需求,介绍了一种结构简单、灵敏度高的金属表面裂纹涡流检测装置,简述了涡流探伤的基本原理,细述了涡流传感器的结构和设计要点以及检测系统的设计。
Aimed at the need of crack detection and welded lines monitoring for rail part, this paper instructs a fitting for detecting the crack on the surface of the metal based on eddy, with simple structure and high delicacy. It simply instructs the fundamental of the eddy testing （ ET ） ; details the particular structure and key point of sensor, designs of the whole system.
