Crack depth determination with the potential probe method is based on the measurement of the electrical resistance between two points on the surface of a metallic work piece. A probe with four spring-loaded and gilded contact pins is positioned across the crack to be measured on the work piece.
Magnetic Particle Inspection (MPI) can be regarded as a combination of two NDE methods namely magnetic flux leakage and visual testing. Magnetic Flux Leakage is a phenomenon where in the magnetic field is expanded from its normal path due to the presence of the air gap normarlly induced by the presence of the discontinuity (ie crack) on metallic material.
