Radiographic Exposure Time
The time during which an X-ray beam is directed at the film or detector to obtain a sharp and clear image.
Physikalisch-chemischer Wirkmechanismus
The exposure time of transmission radiography refers to the duration during which an X-ray beam passes through the workpiece and hits the film or detector. This process produces an image of the internal structure of the material.
Metallurgical Relevance & Welding Risks
Too short an exposure time can lead to insufficiently sharp images, which hides details and flaws. Too long an exposure time increases the exposure and can damage the film or detector. This can lead to missing information in the image and possible errors in evaluation.
Werkstattpraxis & Handlungsanweisungen
The optimal exposure time depends on the specific properties of the workpiece, the X-ray equipment used, and the desired resolution. Normally, the exposure time is 1 to 5 seconds. It is important to follow the manufacturer's recommendations and to regularly check the image quality.
