Phased array ultrasonic in-situ automatic detection system

The invention provides a phased array ultrasonic in-situ automatic detection system, which comprises a scanning module, a detection module and a detection module, wherein the scanning module is used for driving a phased array ultrasonic probe to perform vertical scanning on a detected part to obtain an ultrasonic image; the motion control module is used for controlling the scanning module to move; the imaging and analysis module is used for analyzing and judging the received ultrasonic image; and the coupling water circulation module is used for providing, collecting and storing coupling water during ultrasonic detection. According to the invention, the problem of limited detection enforceable space caused by a pressing claw is effectively solved, the coupling problem of vertical detection and the automatic marking problem of a long longitudinal seam are solved, and detection personnel are helped to better evaluate defects; accurate, efficient and in-situ phased array ultrasonic automatic detection of the int
