Abstract:With the uninterrupted emergence of new materials and the requirements of modern industry for the qualities of components, a considerable development has been got on ultrasonic testing techniques. The achievements obtained in research home and abroad last several years are reviewed, including ultrasonic guided wave technique, advanced technology of acoustic emission, ultrasonic non contact coupling method, ultrasonic signal processing and pattern recognition. The achievements have not only academic forward positions, but also backgrounds of applications.
Keywords:Ultrasonic testing  Development  Acoustic emission testing  Signal processing  Mode identification
