Radiographic testing (RT)

Radiographic Testing is a non-destructive testing method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials.

 

 

Either an X-ray generator or a radioactive source can be used as a source of photons.
The result is a two-dimensional projection of the part onto the film, producing a latent image that after development shows varying optical densities according to the amount of radiation reaching each area. It is known as a radiograph.
 

The detection of very small defects is possible with a micro-focus tube. CEWAC has a special micro-focus tube which allows radiographic testing over the entire 360° circumference of pipes.

The developments realized in the medical field are now used for industrial radiography allowing for faster numerical acquisition of the images. This method is also environmentally friendly because there are no films or development required.

 

The digital radiography cabin allows the radiographic observation of parts in real time. The CEWAC cabin allows testing of parts with a maximum diameter of 600 mm, a maximum height of 900 mm and a thickness between 5 and 25 mm. We are also able to realize tomography studies (3D reconstruction of parts).

 

Application fields :

  • Cast parts
  • Forged parts
  • Welded parts and pipes
  • High definition radiography
  • Archaeology
  • Works of art
