Radiographic Testing (RT) is a type of Non-Destructive Testing (NDT), where we examine the test piece or job using radiographic techniques. These methods help identify defects located beneath the surface of materials.
Testing Process
- This process is harmful to health due to the use of radioactive elements like X-rays or gamma rays.
- A special camera carries the radiographic material, which emits radiation during the inspection.
- The emitted rays pass through the test piece/job and expose a radiographic film placed behind it.
- The film captures the shape and size of internal features and defects during the exposure time.
- After exposure, the film is developed and becomes ready for inspection.
- Level-II Qualification is mandatory for performing and interpreting RT inspections.
