NDT & Metrology

Industrial CT Scanning for Aluminium and Lightweight Metals

Generally, to determine porosity for aluminum 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 or applying pressure or fixtures to the part. Industrial CT scanning (3D x-ray) is used to detect flaws inside a part, such as porosity, inclusions or cracks, before a failure can occur. CT scanning allows you to inspect and locate complex problem areas inside a component, and find the point of origin of a failure without needing to disassemble the components.

Die casting / lightweight metal castings (including aluminum castings) 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 voids 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 (if any), as well as providing access to an overall percentage of the porosity. Jesse Garant & Associates is a metrology laboratory offering services for industrial CT scanning (3D x-ray), a NDT method.

At JG&A Metrology Center, we use industrial computed tomography (CT) equipment to provide our clients with a non-destructive testing method for internal part inspection. Industrial CT scanning is an x-ray technology which allows a part to be scanned in Free State form, with thousands of x-ray images captured through 360 degrees of rotation. The images are reconstructed into a 3D model and can be used for multiple types of analysis offered at JG&A Metrology Center, including void analysis, part to CAD comparison, reverse engineering and more.

After contacting our experienced staff to discuss your internal part inspection requirements, a feasibility study is conducted to pair each project with the right machine.  This allows us to ensure all of the client’s needs are being met at the most cost effective solution. Once the parts have been scanned and analyzed by our experienced staff, a web conference is hosted with the customer to review the results and ensure we have met all project requirements.  Furthermore, the client is also educated on how to use the supplied freeware viewing software.

JG&A Metrology center is capable of scanning parts manufactured from one or multiple materials.  Our cone beam, line beam and planar CT systems can accommodate very small to very large complex parts, ranging from .020” in length up to 26” in diameter by 39” in length.  We are pleased to work with clients that only have one part all the way up to clients who require several thousand parts needing inspection.
