International trends in phased array ultrasonic testing Li Yan (Wuxi Institute of boiler and Pressure Vessel NDT Committee, Wuxi 214026) Abstract: phased array ultrasound (UT) probe array element excitation (amplitude and delay) is controlled by the computer, all the advantages of beam parameters such as angle, focal distance and can be adjusted by software. Introduces the ultrasonic phased array technology in industrial application, and other examples of dynamic, including aerospace, nuclear power equipment, pressure equipment in the system in the detection of complex geometry, or close to the detection of the workpiece is limited adaptability and superiority of quantitative characterization of defects. This paper also introduces the standards, trends and regulations of phased array application, and introduces the requirements of phased array operation demonstration, which aims to provide reference for the popularization of the new technology in china.
