X-ray testing / computed tomography

With help of the X-ray examination the inner workings of components can be displayed in 2D or by computed tomography ( CT ) even in 3D . The defined introduced X-rays are weakened more by inhomogeneities such as pores, cracks, crevices and voids than by dense areas. The attenuation of the radiation is imaged by black and white contrasts. In the computed tomography the specimen is rotated in an X-ray cone beam; this allows the creation of a 3D model.
