MT Level I - NDT testing & certification at WJMG

Other Resources

Magnetic Particle testing (MT) is a nondestructive method of detecting discontinuities in ferro-magnetic materials in which the weld metal is ferro-magnetic. MT cannot be used on non-ferrous material or austenitic steel. Joints between metals of dissimilar magnetic characteristics create magnetic discontinuities that may produce irrelevant indications even though the joints themselves are sound.

This method will detect surface discontinuities including those that are too fine to be seen with the unaided eye. It will also detect those discontinuities that lie slightly below the surface, although sensitivity is reduced and the method should not be relied upon to detect subsurface discontinuities.
