概要
Abstract The NDT method using electromagnetic waves has the possibility to detect widely and quickly inner surface crack existin g in large pipes. The purpose of this study is to demonstrate validity of the method to detect the thin crack introduced by pla sma discharge fabrication. Through this study, it has been shown that both reflected and transmitted waves carry a lot of inform ation on existence of the crack. Experimental results indicate that there exists attractive possibility in this new NDT method.
