Abstract

There are many different non-destructive testing techniques : radiography, ultrasonics, magnetic particles, dye penetrant, eddy current, leak detection, acoustic emission, thermography, vibration analysis, strain gauges, etc... Some are of very large use, whilst other are quite specific. But each has its own range of sensitivity, and of capability to detect one or another kind of discontinuities or to measure one or the other characteristic of the material. So much that the different methods are actually complementary, and from a purely technical point of view, the possibility to compare the results of different methods applied to the same case is always useful!; but it is only feasible of the equipment keep such supplementary costs still acceptable. Basically, a sound knowledge of the capabilities and limits of the different NOT techniques is a basic step when an engineer has to assess the fi ability and acceptability of a part. The fabrication process determines which kind of discontinuity could occur during construction; and the type of equipment and its operating conditions determine what kind of flaws could occur during operation. It is possible then to choose the NOT method the best suitable for the case considered, and knowing the limits of that method, to decide how it should be completed by one or the other special and complementary technique, as NOT holography appears to be
