Method for film-free radiographic testing of components

摘要

The method involves digitally detecting surface geometry (2) of a 18.8 chromium-nickel steel component (1), where digitized surface measurement signals define a high projection surface (4) and a virtually smoothed surface (5). A complementary three-dimensional (3D) element (6) with specific X-ray absorption coefficient is arranged between the smoothed surface and an actual component surface. Digital data of the 3D-element corresponding to the smoothed surface is superimposed with digital signals of a X-ray detector (8) to produce an uninfluenced X-ray image of the geometry of the component.
