MAGNETO-POWDER CONTROL

This method is used to detect surface and subsurface defects and/or discontinuities in ferromagnetic materials. The magnetic field acts on the part, and the iron particles are magnetized while the part is being magnetized. Defects and/or discontinuities are detected when particles collect and form an indication in a magnetic field, which gives an indication of the size and location of the indication.

Magnetic powder is applied to welds, fittings, pipelines, castings, forgings, pressure vessels, machined parts, shafts, valves and structural steel.
