X射线工业电视探伤是近年来发展起来的一种新的无损检测技术。早期的X射线探伤,由于受设备条件与技术水平限制,多用照相法。这种方法不仅耗费大、速度慢,而且不能直观地、及时地得到探测结果和作动态检查。随着科学技术的发展,工业上一些受力复杂、工作条件苛刻、形状奇特的零件,如:曲轴、汽缸、发动机叶片等,亦采用铸件,而铸件生 X-ray industrial television flaw detection is a new nondestructive testing technology developed in recent years. Early X-ray detection, due to equipment conditions and technical limitations, multi-camera method. This method is not only expensive, slow, but also can not intuitively and timely detection results and for dynamic inspection. With the development of science and technology, some industries have complicated forces, harsh working conditions and strangely shaped parts such as crankshafts, cylinders and engine blades. Castings are also used,
