Industrial Radiographic Testing
Industrial radiography uses short-wavelength X-rays or gamma rays to detect internal volumetric defects in metals. The gray value contrast on the detector shows the position and size of the defects.
Physical-Chemical Mechanism of Action
Industrial radiography uses short-wavelength X-rays or gamma rays to penetrate metal workpieces. Materials with different densities and structures absorb the radiation to varying degrees. This results in a gray value contrast on the detector image, showing the position and size of flaws or defects.
Metallurgical Relevance & Welding Risks
This testing is especially important for weld and workpiece inspections. It can detect internal pores, cracks, distortions, or incomplete weld volumes that optical inspection methods cannot reveal. Missing or poor radiography can lead to safety risks and production errors in mechanical engineering and electrical engineering.
Workshop Practice & Instructions
For successful radiography, it is important that the test object is clean and free of dust. Radiation measurement should be performed in a shielded area to ensure radiation safety is maintained. Detector image analysis should be done by qualified technicians to obtain accurate results.
