How should the coupling material be flaw detection?
Here is the title one h1 placeholder text
Flaw detection methods of coupling materials are mainly as follows:
1. Ultrasonic flaw detection: through the transmission and reflection of ultrasonic to detect the internal defects of the coupling material, can detect cracks, inclusions and other defects.
2. X-ray flaw detection: Using the penetration ability of X-ray, the transmission imaging of the coupling material can detect internal defects and foreign bodies.
3. Magnetic particle flaw detection: magnetic powder is coated on the surface of the coupling material. By applying a magnetic field, the aggregation of magnetic powder at the defect can be observed to detect cracks and defects.
4. Eddy current flaw detection: Using the principle of electromagnetic induction, the sensor detects the electromagnetic field changes caused by eddy current, and the defects on the surface and near the surface of the coupling material can be detected.
When performing flaw detection, it is necessary to select the appropriate flaw detection method according to the specific situation, and operate in strict accordance with relevant standards and requirements to ensure the quality and safety of the coupling material.
