Application of the ultrasonic phased array water immersion automatic detection technology in the quality control of aluminum alloy plates for aviation
Ultrasonic phased array detection technology can be used for beam deflection,beam focusing,sector scanning,linear scanning,dynamic focusing,etc.,with different de-lay law set by computer.Its flexible setting and working mode make it widely used in metal material defect detection.The principle of ultrasonic phased array water immersion automatic detection and common defects of wrought aluminum alloy plate were introduced.One-dimen-sional linear ultrasonic phased array water immersion automatic detection technology was used to detect wrought aluminum alloy plate,the detection results of different types of defects were analyzed,and the application and advantages of ultrasonic phased array water immer-sion automatic detection technology in the quality control of aviation aluminum alloy plate were summarized.
