method is too subjective, the inspection reliability and efficiency are low. With the rapid development of the technologies of the computer, signal analysis and proces- sing, the digitalization, imaging, intelligence and the auto- matization of ultrasonic NDT has become a research focus. Particularly, the application of the ultrasonic imaging tech- nique and the automatical identification defects technique, can not only use an image to show the internal defects of parts, but can also use the modern signal analysis technique for quantitative and qualitative analysis and non-destructive evaluation of the defects. Thus it has an important signifi- cance for controlling product quantity, to research on an intelligent ultrasonic NDT system for complex surface parts.
