Radiography

Supplying Confidence in NDT


Radiographic testing is a widely used method to determine the presence of mainly internal volumetric discontinuities in a wide variety of component parts and material types, either in controlled laboratory or on site environments.
Typical parts tested are castings, welds, fabrications or assemblies, pcb’s and components for reverse engineering analysis.
Materials which may be tested vary from dense metals to light alloys, composites, plastics and ceramics.
Specialist examinations have also been carried out on foodstuffs, fabrics, archealogical finds and works of art.
In this method, X Rays are produced by standard  X Ray generators with a range of energies from  <50 to 320 kV. Other sources of radioactive isotopes such as Iridium 192, Cobalt 60 or Selenium 75 may be used in specific applications, as alternative sources of gamma radiation.
The films used to capture the image and the accompanying film processing units are supplied by an internationally recognised supplier and meet the most stringent requirements of all industry sectors.
All examinations are carried out in accordance with approved techniques in order to meet specific client/specification requirements.
Laboratory examinations are carried out in purpose built exposure bays with controlled access and safety systems to comply with recognised radiation safety practices. Any on site examinations are carried out strictly in accordance with the recommendations of national legislation and the Health and Safety Executive, specifically with regards to safety procedures and advance notifications.
Evaluation of all resultant radiographs and compilation of reports is carried out by experienced and fully qualified scrutineers with many years experience.
