Description

TECHNICAL FIELD

[0002] Ray nondestructive testing is an important technology widely used in the fields of material science and engineering. It detects defects, cracks, inclusions, etc. inside materials without causing physical or chemical damage to the materials by using various rays (such as X-rays, gamma rays, etc.). This technology plays a crucial role in many industries such as aerospace, automobile manufacturing, petrochemical industry, power electronics, etc. due to its unique advantages and wide range of applications. The basic principle of ray nondestructive testing is to use the ability of rays to penetrate materials and the difference in their attenuation characteristics in different materials. When rays pass through the object being tested, they interact with atoms and molecules in the material, causing attenuation of the ray intensity. If there are defects such as cracks, cavities, etc. inside the material, the ray attenuation characteristics of these areas will be different from those of the surrounding normal areas, resulting in different gray-scale images on the ray detection film. By analyzing these images, it can be determined whether there are defects inside the object being tested, as well as the location, size, and nature of the defects.
