Esterer Gießerei - Radiographic inspection

At radiographic testing, in short RT-test, we test materials via Y-ray and gamma radiation. With this non-destructive material testing we search for imperfections and we use it for investigating pores, segregation and cracks in the inner part of casts. Mainly it is used for quality control for security-relevant castings and welding seams.

Mainly it is used for quality control for security-relevant castings and welding seams.

The principle of this method is based on the fact, that different material thickness leaves different levels of darker colouring on the radiographic image. The thicker is the material, the brighter is the projected image. With the aid of contrasts, which are used for the radiation of castings on a roentgen film, we can not only see the differences in the material thickness but also faults in the solidity of the material.
