Fluoroscopy
Fluoroscopy is a real-time radiographic method where X-rays hit an image intensifier, enabling dynamic testing or series inspections.
Physico-chemical mechanism of action
Fluoroscopy uses X-rays that pass through the material. These rays are captured by an image intensifier and displayed in real time. Material density affects how much the rays penetrate, showing different colors or brightness in the image.
Metallurgical relevance & risks in welding
Fluoroscopy is especially helpful for monitoring weld quality and processes. It allows real-time observation of the melting process and detection of defects like porosity or cracks. Incorrect settings can lead to unclear images, which can affect inspection quality.
Workshop practice & instructions
To use fluoroscopy effectively, the X-ray tube voltage and current must be set correctly, and the image intensifier must be calibrated properly. The distance between the source and the object, as well as the exposure time, should be adjusted based on material and inspection goals. For series inspections, it is important to follow a consistent procedure to ensure comparable results.
