In hospitals, X-ray machines are the “eyes” for doctors to diagnose diseases; In factories, industrial X-ray machines are the “super detectives” for engineers to detect internal defects in products. It does not damage objects, but can see through tiny flaws in metals, plastics, ceramics, and even complex electronic components. Today, let’s talk about this “perspective artifact” in the industrial field!
1、 What is an industrial X-ray machine?
Industrial X-ray machine is a non-destructive testing equipment that uses X-rays to penetrate objects and image them. It captures the attenuation signal of X-rays passing through objects and generates high-resolution internal structural images, helping engineers discover problems such as cracks, pores, and foreign objects that are not visible to the naked eye.
Core advantages: No need for disassembly, contactless, high precision, visual results.
2、 Working principle: How do X-rays “see through” metals?
X-ray generation: High voltage electric field accelerates electrons to collide with metal targets (such as tungsten targets), releasing high-energy X-rays.
Penetration and imaging: When X-rays penetrate the object being measured, different materials have varying degrees of absorption of the radiation. Areas with high density (such as metals) absorb more radiation and appear as “white” in imaging; Areas with low density (such as pores) are displayed as “black”.
Digital processing: Modern devices convert signals into digital images and can even generate 3D computed tomography (CT) models, achieving 360 ° blind spot detection.
3、 What does an industrial X-ray machine do? Unveiling Application Scenarios
Automobile manufacturing: detecting internal air holes in aluminum alloy wheels; Analyze the integrity of welded joints.
Aerospace: Check for microcracks inside turbine blades; Ensure defect free composite materials for spacecraft.
Electronics industry: Identifying virtual soldering and short circuits in circuit boards; Analysis of the Internal Structure of Chip Packaging.
4、 Technological Upgrade: From “Black and White Film” to “Intelligent AI”
Early: Relying on darkroom processing of X-ray films was inefficient and not environmentally friendly.
Modern digitalization: Real time imaging of flat panel detectors with resolutions up to micrometers.
AI powered: Deep learning algorithms automatically identify defect types (such as cracks and bubbles), reducing manual misjudgments.
Industrial CT: Reconstruct 3D models through multi angle scanning, accurately locate the three-dimensional coordinates of defects
5、 Frequently Asked Questions and Answers
Q: Is industrial X-ray machine radiation dangerous?
A: The equipment is equipped with a lead shielding layer and multiple safety interlock devices, with radiation levels far below safety standards. Operators need to wear protective equipment and monitor regularly.
Q: How thick can it detect objects?
A: Depending on the energy of the X-ray machine, ordinary models can penetrate 50mm steel plates, while high-energy models (such as 9MeV) can detect castings larger than 300mm.
Q: Why not use ultrasonic or magnetic particle testing?
A: The advantage of X-ray machines lies in their intuitive imaging, which is suitable for complex structures or non-metallic materials such as plastics and ceramics, while other methods may be limited by material limitations.
