Câu hỏi thường gặp (FAQ) dành cho Máy kiểm tra độ cứng Webster
1. What is an X-ray Flaw Detector?
An X-ray Flaw Detector is a non-destructive testing (NDT) device used to inspect materials for internal flaws or defects such as cracks, voids, inclusions, and weld discontinuities. It uses X-rays to produce images that reveal variations in material density and structure.
2. How does an X-ray Flaw Detector work?
X-ray Flaw Detectors emit X-rays through a material, which are absorbed differently depending on the material’s density and internal structure. The remaining X-rays are captured on a detector (film, digital panel, or screen), producing an image that highlights any internal defects.
3. What industries use X-ray Flaw Detectors?
X-ray Flaw Detectors are used in industries like aerospace, automotive, manufacturing, oil and gas, construction, and electronics for quality assurance and safety inspections.
4. What are the advantages of using X-ray Flaw Detectors?
X-ray Flaw Detectors offer high accuracy, detailed imaging, and the ability to inspect internal defects without damaging the material. They are versatile and effective for a wide range of materials, including metals, composites, and plastics.
5. Are X-ray Flaw Detectors safe to use?
Yes, X-ray Flaw Detectors are safe when used properly. Operators must follow radiation safety protocols, including wearing protective gear and ensuring the testing area is shielded from unnecessary exposure.
6. What is the difference between portable and stationary X-ray Flaw Detectors?
Portable X-ray Flaw Detectors are lightweight and designed for field inspections, while stationary systems are larger and provide higher power and resolution for detailed inspections in manufacturing or laboratory settings.
7. Can X-ray Flaw Detectors inspect thick materials?
X-ray Flaw Detectors can inspect thick materials, but their effectiveness depends on the material’s density and the power of the X-ray source. Higher-energy X-rays are needed for very thick or dense materials.
8. What types of defects can X-ray Flaw Detectors detect?
X-ray Flaw Detectors can identify defects like cracks, voids, inclusions, porosity, and weld discontinuities. They are especially useful for detecting internal flaws that are not visible on the surface.
9. How do digital X-ray systems differ from traditional film-based systems?
Digital X-ray systems use digital detectors to capture images, offering faster processing, enhanced image quality, and easier storage compared to traditional film-based systems, which require physical development and storage.
10. What should I consider when purchasing an X-ray Flaw Detector?
Key factors include the material and type of defects you need to inspect, the required resolution, portability, compliance with radiation safety standards, and ease of use. Consulting with experts can help you choose the best system for your needs.
