Digital radiography is becoming increasingly popular in non-destructive tests of welded joints and castings, enabling the obtainment of a repeatable testing method and the minimisation of test time. However, the obtainment of proper test results requires the verification of quality levels (during tests of products) in accordance with a related standard concerning a given product or following the customer’s specification. In terms of digital radiography, the process of preparation significantly affects test results. For this reason, the article discusses the calibration of a testing system, enabling the obtainment of enhanced detectability and the satisfaction of primary quality requirements.
