What is the principle of radiographic testing?
It is based on the principle that radiation is absorbed and scattered as it passes through an object. If there are variations in thickness or density (e.g. due to defects) in an object, more or less radiation passes through and affects the film exposure. Flaws show up on the film, usually as dark areas.Click to…

People also ask, what is meant by radiography testing?Radiographic Testing (RT) is a nondestructive examination (NDE) technique that involves the use of either x-rays or gamma rays to view the internal structure of a component. In the petrochemical industry, RT is often used to inspect machinery, such as pressure vessels and valves, to detect for flaws.Similarly, what is radiographic testing in welding? Radiography or Radiographic Testing (RT) or industrial radiography, is a nondestructive testing (NDT) method of welding inspection or inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials. Also, what is radiographic testing in NDT? 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).How many types of NDT are there?In this blog, we’ll discuss four main types of NDT/NDE – Liquid Penetrant Inspection, Magnetic Particle Testing, Radiographic Testing and Ultrasonic Testing.
