Magnetic Particle Inspection (MPI Machine)

A magnetic Particle Inspection (MPI) Machine is a non-destructive testing device which can identify surface and slight subsurface defects in ferromagnetic materials. It is mostly used to carry out an item's fitness or compliance.

The materials contained in ferromagnetic materials are iron, nickel, cobalt, and some of their alloys. It is used to identify lengthwise cracks through circular magnetization. This machine shows the invisible defects and holds the iron powder which is passed across the electrical conductor in the Testing Machine. It involves a process to put a magnetic field in that part of the testing object which will be tested. There are two magnetised Direct and Indirect.

Direct magnetization is the process that forms when the current travels through the tested object and magnetic field, but when the magnetic field is applied from an outside force there is no electric current it travels through the test object, then the process forms is known as Indirect  Magnetization.

This MPI Machine is mostly used in all industries such as automotive, aerospace, steel, petrochemical, and power generation to detect a variety of products and equipment such as engine, suspension and braking system components, castings, forgings and weldments. It is applied on the tested part to identify a crack, and ferrous particles, either dry or in a wet suspension. It is applied on that area of flux leakage which is assessed to determine its nature, cause, and course of action, to form an indication.

Frequently Asked Questions (FAQs)

1. What is a Magnetic Particle Inspection (MPI) Machine?

An MPI Machine is a non-destructive testing system used to identify surface and near-surface cracks and other discontinuities in ferromagnetic materials. It uses magnetisation and magnetic particles to make relevant defects visible.

2. What is the main purpose of MPI testing?

The main purpose of MPI testing is to examine suitable metal components for cracks, seams, laps and other discontinuities that may affect their quality or service performance.

3. Which materials can be tested using an MPI Machine?

MPI testing is suitable for ferromagnetic materials such as carbon steel, alloy steel, cast iron and certain magnetic stainless steels. It is not suitable for conventional inspection of non-magnetic materials such as aluminium and austenitic stainless steel.

4. How does a Magnetic Particle Inspection Machine detect cracks?

The machine magnetises the component and magnetic particles are applied to its surface. When a crack interrupts the magnetic field, magnetic flux leakage attracts particles around the affected area, producing a visible indication.

5. Is Magnetic Particle Inspection a non-destructive testing method?

Yes. MPI is an NDT technique that helps identify relevant discontinuities without cutting, breaking or permanently damaging the tested component.

6. What types of defects can be identified through MPI testing?

MPI can reveal surface and near-surface cracks, seams, laps and other discontinuities in suitable ferromagnetic materials. Detection depends on defect orientation, depth, material properties and inspection conditions.

7. What is the difference between MPI and dye penetrant testing?

MPI uses magnetisation and magnetic particles to identify discontinuities in ferromagnetic materials. Dye penetrant testing uses a liquid penetrant to reveal surface-breaking defects and can be applied to a wider range of non-porous materials.

8. What is the difference between dry and wet magnetic particle inspection?

Dry MPI uses magnetic powder applied directly to the component, while wet MPI uses magnetic particles suspended in a suitable liquid carrier. The selection depends on the inspection procedure and application.

9. Which industries commonly use MPI Machines?

Automotive manufacturing, forging, foundries, railway manufacturing, aerospace, heavy engineering and steel processing are among the industries that use magnetic particle inspection for suitable components.

10. How can I choose the right MPI Machine for my factory?

Consider the component material, dimensions, weight, geometry, inspection volume, magnetisation requirements and applicable standards. These details help determine the appropriate machine configuration.

11. Does Magnatech RMC manufacture and export MPI Machines?

Yes. Magnatech RMC manufactures, supplies and exports Magnetic Particle Inspection Machines for industrial inspection and quality control applications.
