Magnetic particle testing

Non-Destructive Testing

The check method by magnetic particles is one of most consolidated methods in the field of the not destructive checks. This method consists in the formation of magnetic fluxes that, through suitable devices, are brought inside the component to be checked, this component takes on the function of the penetrating element. In this condition dredging the surface of the component under exam with a metal oxide powder (Magnetic particles), composed by particles with defined colour, form and dimension, we will have a localized concentration of particles on the profile of discontinuity, they shall be visible by Wood lamp.

The MP, for its strengthening on the market, has been the first CND method on which Punto Netto has acquired the technique so today it can count on a big team composed by certified workers. In addintion to mobile devices for testing in plant, Punto Netto has got a magnetic desk DEUTROFLUX UWE 900. This desk allows a massive productivity for mass checks.
