Radiographic Testing

Technical advancements in manufacturing engineering have led to the development of advanced materials with improved mechanical properties. These materials are required to perform consistently in aggressive atmospheres without premature failure. To ensure reliable performance during their service life, materials are subjected to different nondestructive tests (NDT) to ensure that the materials are free from discontinuities and that their dimensions are less than critical discontinuity size. Though conventional film radiography is still used in the NDT industry, advanced radiologic techniques are being explored as an alternative to film radiography. Phosphor image plate based computed radiography is the latest development in this direction. The image produced using such a system is in a digital format, which can be processed to extract more information. This paper describes weld testing using an image plate based computed radiography system and the use of image processing for further evaluation.
