【Abstract】 JTUIS ultrasonic imaging nondestructive testing system can be used to detect low voltage electrical contacts. On the basis of conventional ultrasonic flaw detection,the system combines computer technology,image processing technology to achieve welding quality testing,qualitative and quantitative analysis. This paper reviews the recent development history of the system and briefly introduces JTUIS-Ⅲ,Ⅳ,Ⅳ and Va. Then it mainly describes the research progress and achievements from aspects of hardware and software,which include increased system integration,signal processing,image processing and software optimizing. The experiments and practical application show that the stability,reliability and reproducibility of the improved system are substantially improved.更多还原
