An Overview of X-RAY Inspection
As one of the five conventional non-destructive testing methods, X-ray detection technology has been widely applied in the industrial sector. According to the definition of modern industrial product categories, radiographic testing is mainly divided into three categories: photographic testing, real-time imaging testing, and tomographic imaging.
In fact, X-rays and natural light are essentially the same, as they both belong to the electromagnetic spectrum. However, the energy of X-ray quanta is far greater than that of visible light, allowing them to penetrate objects that visible light cannot, and to engage in complex physical and chemical interactions with matter.
Section II: The Principle of X-RAY Testing
X-rays can penetrate materials that ordinary visible light cannot, with their penetrating ability depending on the wavelength of the X-rays and the density and thickness of the material they pass through. In summary, the shorter the X-ray wavelength, the higher the penetration rate; the lower the density and the thinner the thickness, the easier it is for X-rays to penetrate.
When matter absorbs X-rays or other radiation (such as gamma rays), the molecules that make up the matter are broken down into positive and negative ions, a process known as ionization. The number of ions is proportional to the amount of X-rays absorbed by the matter. The amount of X-rays can be calculated by measuring the degree of ionization in air or other substances.
The basic principle of X-ray imaging is based on the characteristics of X-rays and the differences in density and thickness of parts.
Type of X-RAY Detection Technology Applications
Quality Inspection: X-RAY equipment is used to detect defects in the casting and welding processes (suitable for industries such as industrial and electronics).
2. Thickness Measurement: X-RAY equipment is suitable for online, real-time, and non-contact thickness measurement.
3. Element Detection: X-ray equipment can be used for material element composition detection and analysis (such as ROHS testing, etc.).
4. Security Inspection: X-RAY equipment is utilized for security checks in the public safety sector.
5. Dynamic Research: X-RAY equipment can be used to study dynamic processes such as ballistics, explosions, casting techniques, etc.
Advantages of X-ray Inspection Technology
The无损检测 capability ensures that the inspected items are not damaged, making it convenient and practical. Additionally, it achieves unique detection effects that are unattainable by other methods. For X-RAY equipment with real-time imaging, the detection data is transmitted to the computer screen via a detector, processed by software, and the real-time imaging of the results is displayed, offering clear visibility, ease of operation, and storage, as well as traceability.
