Digital X-ray Radiography
INDUSTRIAL RADIOGRAPHY:
Manufacturers use industrial radiography to ensure that their products are not damaged before the products are sold. Just like medical x-rays are used to find breaks or cracks in bones, industrial radiography uses x-rays or gamma rays to take pictures of products because they can show problems that are not visible to the naked eye. Pictures can also be taken from the inside of an object to make sure that there are no cracks that would be impossible to see from the outside. Radiography is useful because it does not damage or change the item being tested. It can also be used when it is difficult or not practical to access the material being inspected.
For example, industrial radiography is used to test:
⦁ Gas and oil pipelines
⦁ Metal welding
⦁ Boilers
⦁ Vehicle parts
⦁ Aircraft parts
Industrial radiography works by pointing a beam of x-rays or gamma rays at the item being tested. A detector is lined up with the beam on the other side of the item. The detector records x-rays or gamma rays that pass through the material. The thicker the material, the fewer x-rays or gamma rays can pass through. Because the material is thinner where there is a crack or flaw, more rays pass through that area. The detector creates a picture from the rays that pass through, which shows cracks or flaws. The pictures from these cameras are called radiographs. Like photography, industrial radiography has been moving away from film-based radiography and instead moving to digital images.
When you look at a radiograph of welded metal, the welding site shows up bright white because it is thicker than the rest of the pipe material. The welding stops the rays almost completely from passing through, which makes it show up brighter than the rest of the images. The cracks show up as darker areas because the radiation has passed completely through the cracks.
Digital X-ray and gamma ray industrial radiography devices are different and used for different purposes.
⦁ Digital X-ray radiography devices are powered by electricity. X-ray radiography generally creates very clear pictures. The devices are large and good for use in factories. We can inspect any materials such as steel, Aluminium, plastics, Ceramics, etc.,
Our Experienced Radiographers are well- equipped with Technical exposure in taking keen interest in inspecting the component to its utmost Quality Inspection for Production as well as research applications.
