Study of an ultrasonic probe installed in a pipe using an electromagnetic acoustic transducer

Abstract

In order to inspect the inside of a small diameter metal pipe easily, an endoscope using a camera or a visual observation has been put into practical use. But there are a lot of problems to inspect a pip, for example, internal scratches can not be judged. Therefore, an ultrasonic probe installed in a pip using an electromagnetic acoustic transducer has been studied.
