Magnetic Particle Inspection

ASTM E 1444

Magnetic Particle Inspection (MPI) is a nondestructive testing method focused on surface and near-surface/ shallow subsurface inspection of ferromagnetic materials. Parts are subject to a magnetic field and suspended in fluorescent, ferrous particles. These particles are attracted to any localized magnetic flux leakage caused from discontinuities and aggregate to form visible indications. After inspection, parts are then demagnetized before returning to service or continuing to subsequent manufacturing steps, i.e. metal finishing, assembly, installation, etc.


Fluorescent Penetrant Inspection

ASTM E 1417

Fluorescent Penetrant Inspection (FPI) is a nondestructive testing method focused on surface inspection using fluorescent dyes. FPI can utilize a variety of different methods, techniques, and combinations thereof to expose defects caused during the manufacturing process or service in the field that may compromise the integrity or quality of the part. FPI is used on nonporous materials and is ideal for use on metals due to their small pores and smooth surfaces.
