A radiographic testing is a non-destructive volume inspection procedure for structural components during the manufacturing process as well as operating components. It serves the detection of internal errors.
A radiographic testing is based on the fact that homogenous areas and voids or material separations reduce the electromagnetic radiation differently. These so called dose rate differences cause distinct optical densities on an X-ray film.
The application range of radiographic testing is very broad. The procedure is used to inspect welding seams and casting parts, to determine residual wall thickness of pipes or to test forgings.
The stationary inspection is executed in special bunkers or cabins. The mobile radiographic testing is conducted in strict accordance with radioprotection guidelines, e. g. in petrochemical facilities, during the manufacturing process of machine and tank construction as well as on pipelines.
