| Abstract: | The development, principle and characteristics of ultrasonic phased array inspection technology and the classification of its transducers were summarized. Its applications to weld and railway wheel and axle inspection were described. It was showed that ultrasonic phased array inspection technology was high in speed, efficiency, suitable for complicated structure and real-time imaging compared with conventional ultrasonic technique, and was good in application prospect for nondestructive testing of pressure vessels, nuclear power plant and offshore platform structure and so on. |
