Abstract

The guided wave with the bidirectional propagation leads to complex signal which would be difficult to identify the end echo and the flaw echo. To simplify the guided wave signals based on the magnetostrictive effect, one-direction receiving method is investigated. The receiving guided wave method in one direction is obtained from the beam superposition by considering the position of the receiving coils and the direction of the wave propagation. The process of the signal is given in detail. The method is verified by the experiments. Two transmitters and two receivers are applied at the same time which could increase the signal-to-noise ratio by about four times than one transmitter and one receiver.
