Digital Radiography
Digital radiography is a modern radiographic testing method where radiation intensity is directly converted into electronic data. This improves detail detectability and facilitates archiving.
Physicochemical Mechanism of Action
The penetrating radiation (e.g., X-rays) is absorbed or reflected by the material. Digital detectors measure the remaining intensity and convert it into electronic signals, which are then turned into a digital image.
Metallurgical Relevance & Welding Risks
Digital radiography allows more precise analysis of weld quality and structural defects. However, incorrect settings or defective detectors can lead to inaccurate images, affecting diagnosis.
Workshop Practice & Action Instructions
Always use calibrated detectors and check their functionality regularly. Ensure the radiation source provides constant intensity. Image acquisition should be carried out in a controlled environment to minimize influencing factors such as air density.
