N2 - Aluminum plate components has been widely used in the practical industrial applications, because of the plate's defects, a lot of major accidents occurred and caused significant economic loss. Therefore, based on the fundamental theory of the guide wave that propagating in the aluminum plate, and by solving and analyzing the guide wave's dispersion, the guide wave's inspiring method have been obtained from the wave-mode conversion. Using the wavelet to process the testing signal, and introducing the ellipse localization imaging algorithm to identify the defect's orientation, the defect's localization and orientation can be detected accurately. Based on the theory and technique previous statement, a multi-channel ultrasonic transducer array detecting system including hardware and software has been established, and a series of experiments have been done. The results shows that: the multi-channel ultrasonic detecting system established has a high detection precision in defect's localization and orientation detecting, which is up to 98%.
