The device known as a Portable Power Pack MPI Machine is a **Magnetic Particle Inspection (MPI)** device which is very small and also very mobile. The method used in non-destructive testing (NDT) which is composed of different methods, this one is the most significant and MPI is the medium through which the detection of flaws like cracks, seams or inclusions, is done, especially in ferromagnetic materials which are made of iron, steel, and nickel alloys.
The device is built around the basic process of sending a magnetic field to the testing component. The particles when they get to the surface of the defect, cause the field to break, and this results in an indication according to the visibility. The power pack (portable) machine are operated with batteries or can be recharged which makes them suitable for doing inspections on-site in places that are hard to reach like construction sites, pipelines, shipyards, and industrial plants.
These machines are not only light and easy to use but also robust, so they can be used in demanding environments. They have thus eliminated the need for transporting large parts to a laboratory for testing, which saves a lot of time and money while ensuring that the structures are safe and quality is guaranteed.
