Description

Technical Field

[0001] This utility model belongs to the field of industrial CT testing technology, and in particular relates to an industrial CT liquid-gas density resolution test sample. Background Technology

[0002] Industrial CT has emerged as a novel non-destructive testing method in recent years. It boasts advantages such as being unaffected by the material type, shape, or structure of the object being inspected. It can clearly, intuitively, and accurately display the internal structure, material composition, and defects of the object in the form of images. Therefore, industrial CT technology is widely used for qualitative measurement and analysis of material density. However, CT-inspected materials often have high density, a wide range of variations, and complex structures, making accurate quantitative measurement of the workpiece's density difficult. While industrial CT tests liquids and gases separately, traditional qualitative measurements are insufficient for practical engineering applications. Currently, the lack of liquid / gas density resolution test samples leads to low CT density detection efficiency, high inspection costs, and significant equipment wear and tear.

[0003] Therefore, there is an urgent need to develop a completely new resolution test specimen to overcome the problems existing in the current technology. Utility Model Content
