Industrial Computed Tomography at GWP: The Possibilities and Limitations
To create precise volume images, GWP uses computer tomography (CT), a technique that takes a series of radiographic images from a variety of angles. Ideally, the recording area covers 360° so that the object is completely captured from all sides. This is essential to ensure a comprehensive and detailed representation, especially in complex damage analyses.
For compact objects, such as cylindrical or spherical components, this all-round view can be achieved relatively easily. However, the image is more difficult for flat or particularly large parts. Here, physical limits are often encountered, as the component cannot be freely rotated without coming into contact with the X-ray source or detector.
The right balance between X-ray intensity and exposure time is particularly important for dense and voluminous materials. Metals such as copper, lead or tungsten, which are frequently used in industrial production, require high radiation intensity and often a longer exposure time in order to achieve a sufficient signal-to-noise ratio. This ensures that even fine details and material defects remain visible in high-density materials. For lighter materials such as aluminum or plastics, lower radiation intensities can be used, which shortens the exposure times and increases efficiency.
Thanks to the unique and extensive equipment of our CT laboratory with several different CT systems, we can examine an exceptionally wide range of objects and samples. This versatility ranges from extremely small samples of organic material, which can be imaged with a spatial resolution of less than 100 nanometers, to very large objects such as engine blocks or larger machine parts. With our Linear accelerator high-performance CT from diondo We are setting new standards in the service for the three-dimensional recording of large-volume objects. This innovative technology enables us to precisely analyze both internal and external structures and achieve decisive optimizations in the development process.
The limits of our examination capabilities are only reached when the objects are so large that they no longer fit into the system, or when the X-rays are absorbed so strongly by the volume of the object that no signal reaches the sensor. In all other cases, we are able to carry out precise and detailed scans that make even the finest structures and defects visible.
