Radiographic Testing is anNDT examinationtechnique. This method uses radiation (gamma rays or x-rays) to view the internal structures of a component. RT is often used to inspect specialized assemblies such as pressure valves for structural flaws andflux leakage.Moreover, RT can be easily used to inspect weld repairs.
Compared to other testing routines,Radiographic Testingis more convenient as it’s highly reproducible, abundant in material and data collected can be saved for later analysis. RT requires very little surface preparations and is portable. This implies its use in the field where other NDT equipment is rarely used.
