Course certificate: Radiography test (RT) Level I and II (ASNT)
Among the various methods of non-destructive inspection or NDT, the RT radiography test is the most used to identify internal defects such as porosity and holes. It should be noted that with proper orientation and experience, plate defects can also be detected by RT test. Industrial radiography has been continuously and uniformly developing for more than 40 years. Because only with this test and ultrasonic testing, defects can be detected anywhere in the volume of heavy and large parts. Radiography is a volumetric method in NDT that is based on the absorption difference between penetrating radiations in the tested sample. In fact, it is called the use of short-wavelength electromagnetic radiation (such as X-ray and gamma-ray) or the use of particle radiation (alpha, beta, or neutron) to track the internal defects of RT radiography or industrial radiography test pieces.
