The existed semi-automatic ultrasound eddy current testing system is difficult to adapt to the situation of seamless steel tube detection requirements at present. This paper puts forward an ultrasonic eddy current synchronous auto-detection system. The principle of ultrasonic eddy current testing tube and the design of the ultrasonic eddy current probe frame are introduced. Software system uses ultrasonic and eddy current imaging at the same time, and ultrasonic testing’s results can be displayed by A+B+C combination imaging. The quasi three-dimensional imaging system can offer more convenient methods to detect personnel. Experimental results verify the feasibility of the system.
