Magnetic element testing is a type of non-destructive testing which makes different types of irregularities of any metal which comes into the foreground. The reason is it comes under the group of non- destructive elements. It will thoroughly examine the particles without any sort of changes in its physical or chemical properties. The hidden benefit behind this testing is to preserve the original value of the material and the amount of the material that is in question.
Different ways to perform magnetic particle testing
Let’s deeply go through the techniques used behind magnetic particle testing. It involves applying of magnetic particles on the test surface which leads to the accumulation of the particles at the cracked places. It becomes quite easy to rectify the issues after this method.
Some of the common applications of magnetic particle applications are-
Wet particle inspection – In this type of inspection, the particles are left suspended when they applied on the surface. The particles that are used in this method are quite smaller and it can prove to be immobile when it is applied on a rough surface. So, we can conclude that this technique is more suitable to the objects having a smooth surface.
Dry particle inspection- This method is more suitable to rough surface. Here the object surface is magnetized and all the dry particles are applied to the surface. To develop a pulsating effect in the magnetic field, a half wave DC current could be used.
Residual magnetism- Here the particles are applied to the surface of the object once the residual magnetism process is finished or when part of the object is magnetized. However, elongated magnetic effect is proved to be quite harmful and can damage the surface.
In order to purchase magnetic particle, you do not have to go from stores to stores. There are great numbers of online stores which can help you in this regard.
