实现了对金属缺陷的定量检测。

Abstract

The basic principles about pulsed eddy current of inspection system are introduced.A pulsed eddy current nondestructive inspection system is designed to detect the inner corrosion and the time domain signal feature is obtained

such as the peak of voltage and the zero-crossing time.The conclusion is validated by further experiment

which makes quantitative detection come true.
