This service involves the use of radiography or X-ray imaging techniques to inspect and evaluate the quality and integrity of welded rail joints. Below is detailed information about this service:

Radiographic testing is a non-destructive testing (NDT) method that uses X-rays or gamma rays to create images of the internal structure of materials.

During a radiographic test, X-rays or gamma rays are directed at the joint area of the rail. These high-energy radiation sources pass through the material and form an image on photographic film or a digital detector. Any irregularities, voids or defects in the weld will cause changes in the X-ray image.

Radiographic testing is highly effective in detecting internal defects such as fusion, porosity, slag inclusions and cracks in the weld. It provides a comprehensive assessment of weld quality and structural integrity.
