| 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. |

| Keywords: | pulsed eddy current(PEC) peak of voltage zero-crossing time time domain signal feature |
