Radiography (RT) is the most widely used NDT method and is applied to detect internal defects in various materials. In this method, rays (X or Gamma rays) emanating from a radiation source pass through the test material and reach the film placed on the opposite surface of the material. The intensity of the rays passing through the material varies according to the discontinuities in the material and the thickness of the part; therefore, regions irradiated at different rates are formed on the film. After the development of the film, the darkening at different rates that occur on the film creates the leech of the object and discontinuities in the film. In this method, since discontinuities in the direction parallel to the radiation beam can be detected optimally, it requires knowledge and experience about the geometry of the inspection piece or the characteristic of the expected defect.
Our company specializes in steel, aluminum, copper, titanium, stainless steels, etc., such as welding seams, forging and casting. It carries out studies of imaging materials with our X-Ray and Gamma-Ray devices, evaluating and reporting the results.
At the order stage, the shooting technique is decided by our Radiographic Inspection Level 3 specialist according to the customer's demands, technical specifications and international standards (ASME, EN, ISO, ASTM, API etc.).
