Image Quality
Image sensitivity is a measure of the detectability of small details in a radiograph. It is determined using wire or step hole image quality indicators and ensures that fine cracks are not overlooked.
Physicochemical Mechanism of Action
Image sensitivity refers to the ability of a radiograph to reveal the smallest details. It is measured using special test pieces that guarantee certain image qualities.
Metallurgical Relevance & Welding Risks
High image sensitivity is crucial for quality assurance in weld inspection. It helps in detecting fine cracks, hot cracks, and other defects that can arise from inadequate cooling or incorrect welding parameters. Too low an image sensitivity value can cause significant defects to be missed.
Workshop Practice & Action Instructions
To determine accurate image sensitivity, use standardized wire or step hole image quality indicators. Make sure the image reaches at least the required sensitivity level. If in doubt, consult the manufacturer's instructions or contact a qualified metallurgist.
