What Is Radiographic Testing in Welding

Radiographic Testing (RT) – This method of weld testing makes use of X-rays, produced by an X-ray tube, or gamma rays, produced by a radioactive isotope. … Energy not absorbed by the object will cause exposure of the radiographic film. These areas will be dark when the film is developed.

What is radiographic testing used for?

Radiographic Testing (RT) is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects. In Radiography Testing the test-part is placed between the radiation source and film (or detector).

What is radiographic technique?

Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. … To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and is projected toward the object.
