Radiographic Examination (RT) is a Nondestructive Testing (NDT) method that examines the volume of a specimen.
The most important phase of radiography is interpreting the generated image. The effort of the whole radiographic process is centered on this step.
At first impression, radiographic interpretation may seem simple, but a closer analysis of the problem soon dispels this impression. The properly qualified and certified NDT inspector must understand the necessity of image interpretation due to the different failure characteristics of materials that are radiographed.
Defects or flaws, which are overlooked, not understood, or improperly interpreted, can jeopardize the reliability of the material inspected and therefore allow substandard or fatigue induced failures to reach the public.
Further, the radiographic image reader must possess knowledge of mechanical processes and stresses that are inherent in the manufacturing process.
How RT Works
Radiography uses X-rays and gamma-rays to produce a radiograph of a specimen, showing any changes in thickness, defects (internal and external), and assembly details to ensure optimum quality in your operation.
