本文从工作原理、线路结构和程序编制方面研讨了计算机在超声探伤中的应用。它和现有的国产探伤仪配套,可直接在荧光屏上显示出缺陷的位置和当量的大小,也可打印存档。所需的反射波高度可任意选择。整个系统操作方便,计算准确可靠。 This article discusses the application of computer in ultrasonic flaw detection in terms of working principle, circuit structure and programming. It is compatible with the existing domestic flaw detector, can display the position of the flaw and the equivalent size directly on the screen, and can also print the archives. The required height of the reflected wave can be arbitrarily selected. The entire system easy to operate, accurate and reliable calculation.
