How to Remove Tough Residual Magnetic Fields?
Well, some ferro materials attain magnetism which could be quite difficult to remove using general methods of demagnetization. Removing residual magnetism is not easy as said. It need skilled engineers, right technique and equipment. With over two decades of experience in giving demagnetization services for customers in Bangalore, Hosur, Mysore, Mangalore, Pune and Hyderabad, even tough to remove magnetic fields also are successfully demagnetized. You can outsource demagnetization services to us.
What is acceptable Residual magnetic Field in any material?
We will do the analysis of existing magnetic field, establish proper method for the process and do the procedure as needed. At the end of demagnetization, you can check to ensure residual field is within the set allowable limits. In general, less than 5 Gauss is acceptable for non critical components and 3 Gauss for critical aerospace components.
De-magnetization - an Overview
Reasons for demagnetization
Also some 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. In the following cases it is essential to demagnetize the parts.
Reasons for demagnetization are clearly indicated here. If the answer for any of one or more of the following is ‘Yes’, then demagnetization is required.
- Residual field will affect instruments sensitive to magnetic fields, e.g., aerospace parts
- Components/Structures to be plated or painted because adhering particles would interfere with these processes;
- Parts are to be subsequently machined
- The part is to be re-magnetized at a lower level than the initial magnetization step
- Component tested will be moving parts. Particles of metal or magnetic particles could cause failure
- When parts are to be electric arc welded; this prevents possible arc blow
Reasons for Demagnetization Not Required
- Post cleaning is not a stringent requirement and all inspection materials need not be removed;
- The component if finished and NO external field exists
- Parts are of low retentivity, e.g. low carbon plate;
- If the material tested consists of structural parts, e.g. weldment, large castings;
- Component is to be heat treated above curie temperature
- When the part is to be re-magnetized in another direction at the same or higher level than the original magnetization;
If the part will be magnetized anyway in a following process, e.g. held on a magnetic chuck
Measuring Residual magnetism
Then, how do you know if the demagnetization is properly performed or not. It is simple, just measure the residual magnetism using residual magnetic field meter. Calibrated magnetic field testing equipment, Instruments are available for measuring magnetic field strength post completion of demagnetization process. Test report is issued with magnetic strength measured in Gauss or Tesla. Rely on our experts for the MPI testing and demagnetization services from our labs at Peenya, Bangalore in India.
