Magnetic Particle Testing (MPT)

 Magnetic Particle Testing 

 



Magnetic Particle Testing (MPT), also known as Magnetic Particle Inspection, i.e. a nondestructive examination (NDE) technique used to detect surface and  subsurface diecounitinuties  in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. Because it does not necessitate the degree of surface preparation required by other nondestructive test methods, conductingmagnetic particle test

Is part of ASME SECTION V ARTICLE 7requires the magnetic particle visible method (color contrast) be evaluated with a minimum light intensity of 100 footcandles on the part surface

Advantages of the Magnetic Particle method of Non-Destructive Examination are: It is quick and relatively uncomplicated. It gives immediate indications of defects. It shows surface and near surface defects, and these are the most serious ones as they concentrate stresses.

Magnetic Particle Testing (MT), also referred to as Magnetic Particle Inspection (MPI), is widely performed in accordance with ASTM E1444/E1444M. The magnetic particle testing method is used to detect cracks, laps, seams, inclusions, and other discontinuities on or near the surface of ferromagnetic materials.

 Causes of Weld cracks: Use of hydrogen when welding ferrous metals. Residual stress caused by the solidification shrinkage. Base metal contamination. High welding speed but low current. No preheat before starting welding. Poor joint design. A high content of sulfur and carbon in the metal.
