Radiographic Image Quality Assessment
The image quality test for radiography determines the quality and sensitivity of X-ray or gamma-ray images. It ensures that even smallest defect structures are recognizable.
Physikalisch-chemischer Wirkmechanismus
The image quality test for radiography uses special pins or thin wire models to measure the radiation density and distribution. These measurements show how well an image can detect defects.
Metallurgical Relevance & Welding Risks
Poor image quality can lead to the failure to detect the smallest defects or cracks. This can lead to safety risks and additional costs due to rewelding.
Werkstattpraxis & Handlungsanweisungen
Use standardized thin wire or step pins for the test. The radiation density should be at least 10 µm/mm to detect the smallest defects. For insufficient image quality, a new radiograph is required.
