Can 3D Engineering Solutions find porosity of a 0.2mm size?
Recently, 3D Engineering Solutions was asked if we could detect porosity of a 0.2mm in a customer casting.
Finding your 0.2mm porosity should not be an issue.
We use Perkin-Elmer 16”x16” Panel detectors with a 0.200mm pixel pitch. That means that for each of the thousands of x-rays taken of your casting, the individual pixel size is 0.2mm x 0.2mm. So basically, the panel will see right at a 0.2mm defect. Beyond this, two other factors work in our favor: magnification and Sub-Voxel Resolution.
