Magnetic Particle Inspection (MPI) Equipment Introduction

Magnetic Particle Inspection (MPI) is the process of identifying surface and somewhat sub surface discontinuities in ferromagnetic materials, and also it is a type of testing called non-destructive testing (NDT).Some of their composites are nickel, iron, cobalt. In this process, a magnetic field inserts into the part. Through direct or indirect magnetization the piece can be magnetized. When the electric current is breezed through the test protest and an attractive field, Direct Magnetization happens in the formed material.

Indirect Magnetization happens when no electric current is passed through the test article, but from outside magnetic field is applied. The magnetic lines of the drive are opposite to the bearing of the electric current, which might be either Alternating current (AC) or some type of direct current (DC) (corrected AC).

Magnetic Particle Inspection (MPI) testing equipment is intended to be solid, quick, and high-esteem. Strong and Flexible for modern situations, Magnaflux wet seats, power pack and magnetic yoke in a scope of yields, including Alternating Current, half-wave Direct Current and full-wave Direct Current. For particular test parts and to oblige any size part, Magnaflux MPI hardware can be estimated.

Applications of MPI

MPI can be accomplishing through either using dry particles or particles suspended in a fluid. In dry strategy, the particles are gently cleaned on to the exterior. And with the wet technique, the part is flooded with a result conveying the particles.

The more convenient strategy is the dry method. The wet method is by and large more touchy since the liquid bearer gives the magnetic particles extra mobility


Magnetic Particle Testing (MT) is utilized to recognize cut-off, open-to-surface or subsurface (for the most part down to some mm profound), just on ferromagnetic substances. Among Different focuses, one might say that Magnetic particle Testing is more “prohibitive” than Penetrant Testing (PT) yet is favoured as being much quicker.
