Radiographic Digital Detector Evaluation
Digital radiography evaluation is a computer-assisted method for analyzing X-ray data with flat panel detectors. It improves the signal-to-noise ratio and contrast resolution, making the identification of internal inhomogeneities more precise than with analog film technology.
Physikalisch-chemischer Wirkmechanismus
Digital radiography evaluation uses flat panel detectors that convert X-rays directly into digital signals. These signals are then processed on a computer, improving the signal-to-noise ratio and increasing contrast resolution.
Metallurgical Relevance & Welding Risks
This method enables more precise analysis of weld qualities, since it can sharply identify the smallest inhomogeneities and defects. This leads to improved defect detection and to the reduction of cracks and hardness problems in the weld zone.
Werkstattpraxis & Handlungsanweisungen
To successfully use digital radiography evaluation, the following steps should be observed:
1. Use high-resolution flat panel detectors to ensure clear X-ray imaging.
2. Optimize the computer system's settings for signal processing for the optimal signal-to-noise ratio and contrast resolution.
3. Compare the digital X-ray images with reference images to identify inhomogeneities and defects.
