X-ray industrial computed tomography in material analysis and quality control


Defect Detection and Analysis

X-ray industrial computed tomography (CT) technology has outstanding advantages in workpiece defect detection. Through high-resolution X-ray scanning, industrial CT is able to detect tiny defects hidden inside the material, such as porosity, cracks, inclusions and sparsity. These defects can affect the strength, durability and reliability of the material, so early detection and analysis of these defects is essential to ensure product quality and safety.

Material Structure and Composition Analysis

Industrial CT technology not only detects defects, but also provides a detailed analysis of the material structure and composition. The internal structure and organizational morphology of the material can be observed very clearly through CT images. At the same time, through specific imaging algorithms, quantitative compositional analysis is performed to determine the content and distribution of various components in the material. This information is very valuable for material development, quality control and performance optimization.

Dimensional measurement and geometric analysis

Industrial CT technology also plays an important role in dimensional measurement and geometric analysis. Through CT images, it is possible to measure the dimensions, shapes and geometric features of the internal parts of an object that are not covered by ordinary measurement precautions, and to realize accurate measurement of complex components. This is essential for quality control and accuracy verification of precision parts and assemblies in manufacturing.

Quality Control and Improvement

The application of X-ray industrial CT technology is not only limited to the product inspection stage, but also allows real-time monitoring and improvement during the manufacturing process. Through CT technology, quality problems that may occur during the production process can be detected on the production line in a timely manner, and corresponding measures can be taken to adjust and improve, thus improving the consistency and quality stability of the products.


In the aerospace industry, industrial CT technology is used to detect internal defects and geometrical patterns of core key components such as aircraft engine blades to ensure their safety and reliability. In the automobile manufacturing industry, industrial CT technology is used to detect the quality of engine and transmission system components, braking system and body structure, to improve the performance and safety of automobiles.

In the field of metal processing and 3D printing, industrial CT technology is used to analyze the crystal structure and defect distribution within the material, optimize the manufacturing process and improve product quality. Industrial CT shows great capability in materials analysis and quality control. Its high resolution, three-dimensional imaging and non-destructive features make it an advanced and powerful non-destructive testing method. Industrial CT can not only discover defects within materials, but also provide detailed analysis of material structure, composition, accurate dimensional measurements, and even the product performance through its life cycle. Through continuous technological innovation and application expansion, industrial CT technology will continue to promote research and manufacturing, with significant contributions to product quality and cost reduction.
