Abstract

Based on ultrasonic pulse echo theory, a multi-channel online ultrasonic flaw detection system is developed. It is an intelligent testing system, which is used to detect flaws online in steel plate production. In this system, fault inspection is carried out automatically. At the same time, multi-channel flaw echo and distance-amplitude-curve (DAC) are displayed on screen of PC. In addition, the sensitivity of system is self-correcting and system parameters can be set according to the practical inspection requirements. In this paper, system hardware structure is introduced and especially four-channel ultrasonic flaw detection card is presented in detail. Besides, the methods of high-speed wave acquisition and real-time data processing of flaw echo are described
