X-ray inspection X-ray inspectionX-rays are used to create a shadow image of light and dark, which reveals any flaws or discontinuity in the test piece.A form of nondestructive inspection in which a piece of photographic film is exposed by passing an X ray through a section of aircraft structure. Defects such as discontinuities within the material show up as a difference in the density of the image on the film. An X-ray inspection is used to examine the inside of the structure for corrosion or damage that deforms the structure. For detection of defects in small parts, gamma rays (cobalt-60; iridium-192) may be used. |
