Digital Radiography with Flat Panel Detectors
Digital radiography with flat-panel detectors converts X-rays directly into digital images, enabling fast and precise evaluations.
Physicochemical Mechanism of Action
X-rays are generated by an X-ray device and pass through the material being inspected. Flat-panel detectors consist of a matrix of photodiodes that directly convert the energy of X-rays into electrical signals. These signals are then encoded into digital image data.
Metallurgical Relevance & Welding Risks
Digital radiography allows fast and precise checking of weld quality, including detection of porosity, cracks, and incomplete weld penetration. It reduces time for image analysis and minimizes the risk of human error in manual evaluation.
Workshop Practice & Action Instructions
Use flat-panel detectors for radiographic testing of welds. Ensure the detector matrix is correctly aligned and the material is fully penetrated by radiation. Analyze the digital images for anomalies and compare them with project-specific quality standards.
