Abstract
Due to the particularity of electromagnetic ultrasonic lamb wave excitation, it is difficult to satisfy demand for GJB 3384-98 which requires the Lamb wave detecting device to detect through-holes whose diameter is 1mm and groove whose depth is 0.4mm in a 4mm thick plate. In this paper, the detection capability of Lamb wave is analyzed to find a proper working point satisfying the demand detection. In addition, considering the low signal-to-noise ratio, the receiver matching circuit is redesigned to enhance the echo signal. Finally, a detecting platform is set, and the experiments shows the effectiveness of the method.
