Determining wall thickness using computer tomography (CT) is a precise, non-destructive method for accurately measuring the material thickness in complex components. This method has proven itself in industrial manufacturing and quality assurance, as it enables a comprehensive analysis of wall thicknesses even in components with complex geometries. CT-supported wall thickness analysis plays a role especially where uniform wall thicknesses are crucial for the durability and functionality of components, for example in the automotive, aerospace, plastics and metal processing industries.
Functionality of wall thickness determination using CT
- CT scan and 3D reconstruction: The component is first examined from different angles using a CT scanner, which produces a large number of two-dimensional X-ray images. These 2D images are reconstructed using special software into a detailed 3D model that depicts the entire geometry and internal structures of the component.
- analysis of wall thicknesses: Using the 3D data, the software can calculate the distances between the inner and outer surfaces at any point. These measurements are extremely precise and allow the wall thickness to be determined accurately across the entire component. The wall thickness is usually visualized in the form of a false color representation, which uses color to demarcate different thickness ranges and makes weak points easily recognizable.
- Automated evaluation: The CT software also enables automated analysis of wall thicknesses, comparing the values with target values. This simplifies the evaluation and ensures fast and reliable quality control.
Applications of CT-based wall thickness analysis
Wall thickness determination using CT is used in numerous industries:
- Automotive industry: Here it is used to check the wall thicknesses of engine components, lightweight components and safety-relevant components.
- Medical Technology: CT scans are used to check the wall thicknesses of implants and medical devices to ensure they meet the required specifications.
- Plastics industry: Accurately measuring the wall thicknesses of plastic parts helps maximize material savings without compromising structural integrity.
- Aerospace: Here, wall thickness analysis is indispensable to ensure the load-bearing capacity and safety of components under extreme conditions.
Advantages of wall thickness determination by CT
- precision: CT-based wall thickness measurements are extremely accurate and detect even the smallest deviations.
- non-destructiveness: The components remain intact and are ready for further testing or use.
- Complete recording: The method records the wall thickness across the entire component, even in hard-to-reach places.
- time savings: Because the analysis is automated and the entire wall thickness is checked in one pass, CT-based measurement is faster than many conventional methods.
