| Abstract: | The default's position influences the result of the electromagnetic acoustic transducer (EMAT) used on detecting in the steel pipe, so the experimental program was designed. The conclusion was that the EMAT couldn't detect the default underneath the transducer by theoretical and experimental analysis. |

| Keywords: | electromagnetic acoustic transducer the position of the default in the steel pipe the ultrasonic wave |
