PROFESSIONALSERVICES ON DE-MAGNETIZATION
Experts in De-magnetizing to Limit Residual Magnetism
Why de-magnetization ? – An Overview
Magnetic particle testing or inspection or magnaflux testing of engineering components is predominantly used on Ferrous materials such as Automobile components, Shafts, Rotors, Blades, Gears, Sprockets, weld joints, plates, other precision engineering components and Aircraft components and structures to find surface and subsurface cracks, linear discontinuities, fatigue cracks during in-service inspection of process plants and machineries. However, some materials are easy to magnetize and easy to demagnetize. However, some materials retain large amount of residual magnetism causing issues during usage or service life of the component. It basically depends on Hysteresis / Magnetic characteristics of given materials.
Also some engineering materials are subjected to magnetizing fields during manufacturing, storing, handling and transporting. Such materials are detrimental for use and use of such material having exceedingly more residual fields are strictly prohibited by international codes, standards and OEM specifications. In the following cases it is essential to demagnetize the parts.
- Components/Structures to be plated or painted. Adhering particles would interfere with these processes;
- When the part is to be re-magnetized at a lower level than the original magnetization step;
- When parts tested will be moving parts. Particles of metal or magnetic particles could cause failure;
- When parts are to be subsequently machined;
- When parts are to be electric arc welded; this prevents possible arc blow;
- When the residual field will affect instruments sensitive to magnetic fields, e.g., aircraft parts.
