NDT & Metrology

Magnesium and Lightweight Metal Inspection Utilizing X-ray Computed Tomography

Generally, to determine the porosity for magnesium and lightweight metals, destructive testing would be required. CT scanning is a NDT method, utilizing x-ray technology that can detect internal features and flaws without destroying the part. Industrial CT scanning (3D xray) is used to detect flaws inside a part such as porosity, inclusions or a crack before a failure can occur. CT scanning allows you to inspect and locate problem areas inside a component, and find the point of origin of a failure without needing to disassemble the components or apply pressure or fixtures toward them.

Die casting / lightweight metal castings, including magnesium castings and magnesium injection moldings are typically prone to porosity because of cooling processes, transitions between thick and thin walls and material properties. Void inspection can be used to find, measure and analyze porosity inside plastic or metal components.  A measurement of each void volume is stored in a chart, and can be exported into an excel file. The CT viewing software allows the user to see where the largest void is (or any void), as well as providing an overall percentage of the porosity.
