Magnetic Particle Testing: What Is It?

Magnetic Particle Testing: You may have heard it many times  before, but you are still not sure about what it is. Magnetic particle testing seems like rocket science to you. But don’t worry, it is indeed pretty close to rocket science.

In this article you are going to find out what magnetic particle testing is, when it is used and whether or not you are going to be needing it anytime soon.

Understanding the term
The term is used to define a non destructive test method of inspecting / testing areas of ferromagnetic surface. The aim of the process is to identify discontinuities in the surface.

How does it work?
Where the cracks or discontinuities are identified, a technician will mark the affected areas and will establish whether or not the material complies with the agreed quality levels.

The irregularities are identified using a special magnetic powder. This is known as iron oxide. The tests can be run either on dry or wet surfaces, depending on the type of test and type of tested material. However, the iron oxide can be used in both cases.

When do you need non destructive testing?
If you are like most people, then you are not going to be needing it very soon. Probably never.  But if you work in the metal industry, if you are a technician or steel forging professional, then perhaps this is what you do on a daily basis.

These checks are performed to evaluate equipment quality and plant safety – vital aspects of every industry. But they cannot be run by an unprepared individual. This is why whenever you want to run a magnetic particle testing it is better to ask for help from the professionals. There are many companies which specialise in this kind of non destructive testing, so make sure you find the best out there.
