一、概述 X射线电视探伤技术是把工业电视应用到X射线无损检验中,在不破坏被检验物体形状、结构的情况下,检验物体内部缺陷的一种方法。当被检查物体内部存在缺陷时, 在电视荧光屏上可以直接观测。与通常的X射线照相方法相比,X射线电视探伤法具有检验结果快、效率高、节省胶片等许多优点。因此,目前有关工业部门对此都给予了很大的重视。我们现在制作的X射线电视探伤仪只是对此种技术所作的初步试验。采用的方案是 I. Overview X-ray television detection technology is the application of industrial television to X-ray non-destructive testing, without destroying the shape and structure of the object under test, a method of testing the internal defects of objects. When there is a defect inside the object to be inspected, it can be directly observed on the television screen. Compared with the usual X-ray radiography method, X-ray television detection method has the advantages of fast test results, high efficiency, film saving and the like. Therefore, the relevant industrial departments have given this a great deal of attention. The X-ray video flaw detector we are now producing is only a preliminary test of this technology. The solution is
