What is the magnetic particle control?
Magnetic particle inspection is a method of non -destructive testing that can be used in the evaluation of all iron materials. Like other forms of non -destructive testing, this method has the advantage that it does not harm or threaten the test materials during the test process. This method is one of the fastest and least expensive ways to test iron materials before certifying them as safe and ready for use.
In the magnetic particle inspection, the tested object is surrounded by a magnetic field. The particles suspended in the load -bearing liquid are sprayed onto the object. If an object defect occurs, this will cause adequate distortion in the magnetic field that is easy to see when the particles are pulled towards distortion. If there are no defects, the particles should remain evenly distributed. This testing can be used to evaluate finished parts and products before they are released to the market, except that they were used in inspection of raw material boards to check the deficiencies thatcould endanger future performance.
Ferlous of the metal parts in the service can also be checked using this technique. Equipment, such as aircraft and production parts, must normally be checked to check signs of fatigue, tension and other problems to confirm that it is safe for use. The magnetic particle inspection is one technique that can be used during the inspection. If a part or machine fails in the inspection test, it indicates that further work is needed to ensure safe.
dyes can be added to particles to make it easier to see, including dyes that will react to ultraviolet light. With ultraviolet particles, testers can perform magnetic particles of UV inspection and clearly visualize particle distribution. The lifted particles will also take pictures well, allowing people to easily read the documentation of the inspection results.
There are additionalInspection techniques to evaluate iron metals. Some of these techniques can be used in addition to the inspection of magnetic particles for complete inspection, while others may be used under certain circumstances. All these techniques require extensive training in non -destructive testing to confirm that they are properly performed. If the test is wrong, a false negative result can be obtained, which leads people to the belief that something is safe when it is not.
