Radiographic Image Quality Indicator
A standardized test object with fine wires or holes used to check the quality of X-ray images. It ensures that image details are sharp and recognizable.
Physikalisch-chemischer Wirkmechanismus
An image quality indicator for radiography consists of a material that is radiographically similar to the workpiece being tested. It contains fine wires or holes that should appear sharp and recognizable in X-ray images.
Metallurgical Relevance & Welding Risks
With poor image quality, important defects such as pores or weld gaps cannot be detected. This leads to safety risks and can endanger the lifespan of components.
Werkstattpraxis & Handlungsanweisungen
Use the test object regularly during every X-ray inspection. Ensure that the material of the test object matches the workpiece being tested. The wires or holes should be at least 0.5 mm wide and recorded sharply. For poor image quality, recalibration of the X-ray machine is required.
