Basics and Principles of RT, X-Ray Testing

Radiography is one of the most widely used and time proven NDT Method to test engineering components to find internal flaws in Castings, Weld Joints and Structures. The method is much suitable for finding volumetric discontinuities and also used for assembled components.

RT is based on differential absorption of penetrating radiation- either electromagnetic radiation of very short wave-lengths (Gamma Rays) or particulate radiation (Alpha & Beta Rays) 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 florescent screen or monitored by various types of electronic radiation detectors to identify flaws and other anomalies.

The term radiography testing usually implies a radiographic process that produces a permanent image on film or digital form. Although in a broad sense it refers to all forms of radiographic testing, Neutron radiography refers to radiographic testing using a stream of neutrons rather than electromagnetic radiation unlike Gamma Rays & X-Rays.

Industrial Radiography – Uses & Applications

Industrial Radiography inspection is used to detect features of a component or assembly that exhibit a difference in thickness or physical density as compared to surrounding material. Large differences are more easily detected than small ones. In general, radiography can detect only those features that have an appreciable thickness in direction parallel to the radiation beam. This means that the ability of the process to detect planar discontinuities such as cracks depends on proper orientation of the test piece during testing. Discontinuities such as voids and inclusions, which have measurable thickness in all directions, can be detected as long as they are not too small in relation to section thickness. In general, features that exhibit a 2% or more difference in absorption compared to the surrounding material can be detected. Radiography is more effective when the flaws are not planar.

Applicability

Industrial Radiographic testing is used extensively on castings and weldments. Radiography is also well suited for testing of semiconductor devices for cracks, broken wires, unsoldered connections, foreign material and misplaced components. Sensitivity of radiography to various types of flaws depends on many factors, including type of material, type of flaw and product form. Both ferrous alloys can be radiographed, as well as non-metallic materials and composites.

Advantages of Radiography

  • RT Technique is not limited by material type or density.
  • Can inspect assembled components.
  • Minimum surface preparation required.
  • Sensitive to changes in thickness, corrosion, voids, cracks, and material density changes.
  • Detects both surface and subsurface defects.
  • Provides a permanent record of the inspection such as Films.

Disadvantages of Radiography

  • Many safety precautions for the use of high intensity radiation.
  • Many hours of technician training prior to use.
  • Access to both sides of sample required.
  • Orientation of equipment and flaw can be critical.
  • Determining flaw depth is impossible without additional angled exposures.
  • Expensive initial equipment cost.
