一、焊接缺陷的超声波图像处理系统该技术是为了确保工厂、造船以及建筑等行业的焊接结构物的可靠性而开发的。超声波图像处理系统是根据以前的 X 线透射试验,并比它有更多的优点。原理采用两个超声波斜角探头,从被检查焊接部分的两侧同时进行探测。因超声波探测器输出信号是通过 A/D 转换器输入到计算机里进行图像处理,探测试验结果立即显示在 CRT(阴极射线管显示器)上。特征1.探测试验结果如同 X 线胶片一样有记录性。2.探测操作容易。二、涡流探测试验信号解析系统涡流探测试验是作为非磁性热交换器管的检查手段而被广泛采用。这项技术是用涡流探测试验将得到的缺陷信号,自动地进行解析评价。主要特点能在 CRT 上表示出缺陷图像。原理进行涡流探测试验时,缺陷深度从缺陷信号的相对位移求得。缺陷的大小从
First, the welding defect ultrasonic image processing system This technology is to ensure that factories, shipbuilding and construction industries such as the reliability of welded structures developed. The ultrasound image processing system is based on previous X-ray transmission tests and has more advantages than it. Principle Two ultrasonic beveling probes are used to simultaneously probe from both sides of the part to be inspected. Due to the ultrasonic detector output signal is input to the computer through the A / D converter for image processing, detection test results immediately displayed on the CRT (cathode ray tube display). Features 1. Detection test results as X-ray film as a record. 2. Detection operation is easy. Second, the eddy current detection test signal analysis system Eddy current testing is non-magnetic heat exchanger tubes as a means of inspection has been widely used. This technology is the eddy current test will be obtained by the defect signal, automatic analysis and evaluation. The main features can be displayed on the CRT defect images. The principle of eddy current detection test, the defect depth obtained from the relative displacement of the defect signal. Defect size from
