Ultrasonic flaw detection imaging system and control method thereof

The invention provides an ultrasonic flaw detection imaging system. The ultrasonic flaw detection imaging system comprises an ultrasonic detection device for detecting the thickness value of a detection point of a detected object by utilizing ultrasonic waves; the encoder is used for positioning the position of the detection point; the data collection card is used for collecting position information of the detection points; and the control, control and processing equipment is used for acquiring position information and corresponding thickness values of all detection points and drawing a corrosion damage image of the detected object. The invention further provides an implementation method of the ultrasonic flaw detection imaging system. The ultrasonic flaw detection imaging system disclosedby the invention can be used for quickly and visually imaging the corrosion condition of a detected object. Parameters of transmitted ultrasonic waves can be adjusted to facilitate detection, and theparameters can be adjuste
