Radiographic Testing

RT is based on differential absorption of penetrating radiation either electromagnetic radiation of very short wavelengths (X-ray) by the part or test piece being tested. Because of differences in material density and variations in thickness of the part, or differences in absorption characteristics caused by variation in composition, different portions of a test piece absorb different amounts of penetrating radiation.

Unabsorbed radiation intensity passing through the part can be recorded on film or photosensitive paper, viewed on a fluorescent screen, or monitored by various types of electronic radiation detectors to identify flaws and other anomalies.

Equipment Used:

  Pulse X-ray
  Eresco 220 kVp
  Computed Radiography (VMI-1400)
  Digital Radiography (NOVO-24K Discovery)
