Magnetic Particle Inspection

Magnetic particle inspection (MPI) reveals surface and near-surface cracks in magnetic steels. The range includes electromagnetic and permanent yokes, dry powders, wet visible and fluorescent suspensions and concentrates, white contrast paint, UV-A inspection lamps, field indicators, calibration shims and reference test blocks.

Typical applications

• Weld inspection
• Crack detection on castings, forgings and machined parts
• Maintenance inspection of shafts, gears and lifting equipment
• Fluorescent inspection under UV-A light
• Checking field strength and direction with indicators and shims

Choosing equipment

Key factors are whether you inspect in daylight (visible method) or under UV-A light (fluorescent method), wet or dry application, the surface temperature of the part, access for the yoke, and the standard your procedure follows.
