The Magnetic Particle Inspection MPI57 checks the real conditions of the crankshaft. The magnetic inspection makes it possible to locate and evaluate the small cracks or hollows, better than by a visual inspection. Sprinkling the crankshaft with detecting fluid containing magnetic particles will be made fluorescent by the ultraviolet light, the contrast between the piece and the cracks becomes stronger, because these particles concentrate in the cracks area. This inspection will allow you to determine if the crankshaft can be refurbished.
