Reasons To Consider Magnaflux Mag Unit Repair

Author : Greg Falk | Published On : 26 Oct 2026

A majority of industries need to test the components of their machines and other devices properly to identify the flaws before repairing or replacing them. The inspectors or the technician need to be skilled in Magnaflux mag unit repair at the earliest, as it is a particle that is used extensively during the process of Magnetic Particle Inspection (MPI). This is a non-destructive testing process that is utilized to find the surface-level or near-surface-level cracks, fissures, and other damage.

The mag unit of Magnaflux is a machine that works in the following manner: -

  • Magnetization- This unit is used to deliver high-intensity electric current through or across the metal part that is being tested for flaws. This creates a magnetic field within it.
  • Magnetic Disruption- There is a leakage of the magnetic field at the spot of the flaws or defects. Identifying the defects thus becomes easier for inspectors, who can identify the exact location of the defects on the metal surface.
  • Particle Attraction- The inspector or operator applies the magnetic particles either in the dry or wet form to the testing surface. The particles are pulled directly into the magnetic leakage field and reveal the exact shape along with the size of the crack.

There are numerous industries that use MPI testing units, thus being sure of using the right components. The following industries usually make use of ferromagnetic metals such as iron, nickel, or cobalt and rely on MPI testing that employs the right mag units: -

  • Aerospace
  • Automotive
  • Oil and Gas / Petrochemical
  • Power Generation
  • Shipbuilding and Marine
  • Structural Steel and Construction
  • Rail and Transportation
  • Manufacturing and Heavy Engineering

The mag units are used extensively by inspectors who may carry them with them for on-site testing. Even the best units undergo wear & tear in the heavy industrial environment, harsh conditions, and age of the unit, contributing to its malfunctioning slowly but steadily. It becomes imperative at this stage to have the unit(s) repaired as soon as possible. Many inspectors also feel the need to have the mag unit refurbished to ensure that the unit exceeds its performance.

The procedure for refurbishment of a mag horizontal wet bench is done by using the right frame, which is then built painstakingly according to the end-user-provided specifications. The entire process is not time-consuming either. On the contrary, it may be ready for use within a month. Moreover, the repair professionals also use new transformers as well as all required electronic components to ensure that the refurbished unit is as good as new. Additionally, the professionals make sure to strip and paint the unit, with its tank cleaned and the headstock plus tailstock rebuilt perfectly.

Any dip in the performance of the Magnaflux power pack is bound to affect the quality of testing. Having it repaired at the earliest can be helpful, as the NDT results may not be up to the mark when the power pack becomes heated during the inspection, revealing inconsistent results during the testing procedure.
