Radiographic Testing

Thanks to the penetration and absorption properties of X-rays and gamma rays, radiography is used to detect expected volumetric and surface defects in castings, forgings and all metallic and non-metallic materials.

High-energy electromagnetic waves (radiation) penetrate various materials and affect radiation-sensitive films placed on the opposite side of the penetrated surface. After development, these films reveal the voids, thickness and density inside the material. This type of imaging method is called radiography. The only limitation in radiography is material thickness; otherwise it applies to all kinds of materials.

Radiation sources can be X-ray tubes or gamma-emitting isotopes. To obtain reliable results, the standards prepared for the material type and/or grade and the application standards for execution and acceptance levels must be followed.
