Magnetic Particle Inspection MPI

When you can't always trust the naked eye, we offer you scientific analysis and inspections, using either back and white and fluorescent technique on Magnetic materials only such as:

 

  • ironmagnetic particle inspection MPI
  • nickel
  • cobalt
  • steel
  • some alloys.

 

The MPI successfully finds surface and slightly sub surface flaws in manufactured products. 

The test piece will be magnetized either directly or indirectly, then iron particles in either a dry or wet suspension are applied. Any flux leakage on the test piece will be indicated by a particle build up at that point, forming an 'indication'.  

If there is an indication sub-surface the Inspector will back up the inspection with an Ultrasonic Test on butt welds.

Expert evaluation will determine what is the root cause and what action should be taken.
