Magnetic Particle Testing (MPT) | Inspectioneering

MPT is a fairly simple process with two variations: Wet Magnetic Particle Testing (WMPT) and Dry Magnetic Particle Testing (DMPT). In either one, the process begins by running a magnetic current through the component. Any cracks or defects in the material will interrupt the flow of current and will cause magnetism to spread out from them. This ...

Intensity Magnetic Separation

Magnetization is a measure of how a material responds to an applied magnetic field as well as how the material changes the magnetic field. For example, some materials intensify the magnetic lines of force within itself, as illustrated by Figure 17.2 b and are referred to as paramagnetic. In contrast, some materials show a weakening of the ...

Magnetic Particle Inspection

Magnetic particle inspection is a simple NDI method used to detect cracks at the surface of ferromagnetic materials such as steels and nickel-based alloys. The inspection process begins with the magnetisation of the component. The surface is then coated with small magnetic particles, which is usually a dry or wet suspension of iron filings.
