Radiographic Image Quality Metric
Radiographic image quality metric is a mathematical evaluation of radiographs to make the smallest flaws visible. It ensures the reproducibility and code compliance of the inspection process.
Physico-Chemical Mechanism of Action
Radiographic image quality metrics measure the quality of radiographs using specific numbers, like duplex wire or step wedge image quality indicators. These numbers assess how well flaws are visible in the images.
Metallurgical Relevance & Welding Risks
Poor image quality can lead to inaccurate inspections, causing errors or misunderstandings in the workshop process. This can result in safety risks and extra costs from re-inspection or re-welding.
Workshop Practice & Action Guidelines
To ensure good image quality, the radiography settings must be precisely adjusted. This includes proper selection of the radiation source, dose, and exposure time. Images should be regularly checked and calibrated to ensure they meet the required standards.
