Investigating internal failures in 3D with Industrial CT Scanning


As every product has modes of failure, inspection becomes a necessary step to determine the root cause. Inspections can be conducted with parts or assemblies that fail perform as intended or when they no longer meet the tolerances initially set by the manufacturer. This process involves collection of data from different types of evaluations. Some failures are straightforward to address, while others are more complex and require significant investment.

Finding the root cause of failures in parts and components often poses a challenge for manufacturers. They can occur for a variety of reasons, including flaws in design, manufacturing defects, and normal wear over time. In the case of Samsung’s Note 7, extensive investigation revealed that both aggressive design and improperly manufactured batteries were behind product failures, according to a recent report.

While many testing methods are available, the right method will vary according to failure conditions, manufacturer requirements, and product life-cycle stage. The common denominator for any part failure is finding out exactly what went wrong and for many part designers and manufacturers, the integrity of that part’s failure cannot be investigated any other way but non-destructively. Industrial CT scanning is one of many non-destructive methods that can be used to perform a part inspection in a completely free state environment. However, industrial CT scanning seems to be the future of many manufacturer’s as the only NDT method capable of adapting to changing conditions that are found within industry.

Performing failure investigations on parts and assemblies using the advanced methods of industrial CT scanning, provides the user with data that will either reduce or eliminate uncertainties. The insights received will help qualify the decisions that need to be made towards taking corrective actions. The underlying benefit is a timely response that won’t create unnecessary expenses during such untimely failures.” – Jesse Garant

CT can determine the internal conditions of an object, reveal any misalignment concerns, and characterize internal features like cracks or porosity. Consistency of both external and internal dimensions of parts can also be verified, allowing manufacturers to identify any out of tolerance dimensions and deviations from original design. Since a virtual 3D model of the part is rendered, the model can be virtually sliced at any given angle and provide a guide for more fine-tuned inspection, should it be required.

CT is particularly useful for inspecting complex systems where there would otherwise be too much overlapping detail for effective inspection with other methods. It is therefore highly suitable for inspection of complex and multi-part assemblies. The technology is also useful for conducting inspection of failures within castings, which are difficult and tedious with other inspection methods and destructive testing. CT can also measure cracks and delaminations in composites, revealing errors in design and fabrication and allowing timely assessment of material quality.

Industrial CT Scanning plays an integral part early in the manufacturing process when it comes to inspecting complex parts. Industrial CT scanning is setting a new standard in qualifying production parts quickly and accurately while reducing inspection costs. This is achieved by using the right technology, expert analytical support, and proper scan calibration to ensure accuracy. The accuracy, efficiency, and reduced turnaround times provided by industrial CT Scanning ensures that it will continue its trend of becoming a required tool for part inspection, as industry leaders are identifying both the value in inspection standards and the cost-effectiveness it offers.
