Magnetic Particle Inspection
Find flaws, reduce downtime, and boost efficiency with our industry leading service
Magnetic Particle Inspection (MPI), also known as Crack Testing, is a Non-destructive Testing (NDT) method that uses magnetic fields to find surface and near-surface flaws in ferromagnetic materials such as carbon and iron. This versatile and powerful Non-Destructive Testing (NDT) method unveils the hidden strengths and potential weaknesses of your materials, ensuring the safety, quality, and reliability of your operations across diverse industries.
Unlock the secrets of your materials with Magnetic Particle Inspection
Imagine a world where every flaw, no matter how minuscule, stands exposed...
Magnetic Particle Inspection (MPI) empowers you to achieve this vision, employing magnetic fields that meticulously probe the surface of ferromagnetic materials, leaving no crack, void, or imperfection hidden. The magnetic ink, like a beacon of detection, gathers around these flaws, revealing their presence with a stark contrast.
MPI’s reach extends far beyond ordinary boundaries, embracing a diverse array of ferromagnetic materials, including iron, nickel, cobalt, and their alloys. Its adaptability makes it a preferred choice for inspecting intricate geometries and complex components, ensuring that no flaw escapes your scrutiny. Whether you’re scrutinizing welds, castings, or forgings, MPI stands ready to unveil the truth concealed beneath the surface.

MPI stands apart from other NDT methods as a non-destructive testing technique, ensuring the pristine condition of the material being inspected. Unlike destructive methods that leave behind scars, MPI leaves no lasting mark, preserving the integrity of your assets for continued service.
The MPI process unfolds with meticulous precision, ensuring that every flaw is exposed and identified:
1. Surface cleaning
The stage is set for revelation as the surface is thoroughly cleaned, eliminating any debris or contaminants that could hinder the magnetic field’s penetration.
2. Magnetic field applicaition
A magnetic field is applied to the material using a coil or a magnet, inducing a pattern of lines of force across its surface.
3. Iron particle application
A dry powder or liquid suspension of magnetic particles is then applied to the surface. These particles align themselves along the magnetic field lines, creating a uniform pattern.
4. Visual inspection
Any areas where the magnetic field is disrupted, indicating the presence of a flaw, will appear as voids in the pattern of iron particles.
5. Results evaluation
The indications given from the inspection are reviewed to determine the severity of any defects.

FAQs
What are the limitations of MPI?
+
It isn’t as sensitive as other NDT methods, such as ultrasonic testing, and can only be used on ferromagnetic materials.
Unless you are an expert, it can be difficult to interpret the results.
