DEMAGNETIZATION SERVICES IN BANGALORE, hosur & mysore india

Experts in De-magnetizing Engineering components to remove Residual Magnetism. Contact Us now.

Demagnetization services in Bangalore, Hosur & Mysore in India

 

By virtue of process some materials will attain residual magnetism. Residual magnetism causes problems in using the components. For example, it is difficult to weld or machine the parts that has residual magnetism. This may also cause surface finishing issues. Therefore, such components needs demagnetization so that residual magnetism is reduced to acceptable level. This needs, experts who have thorough understanding of magnetic field direction, strength and material magnetic properties before starting demagnetization.
 
The Magnetic particle inspection division of Trinity NDT Labs in Peenya Bangalore gives expert demagnetization services to customers in and around Bangalore, Hosur, Mysore, Mangalore, Pune and Hyderabad. A Range of demagnetizing machines available for effectively giving demagnetizing services for the components to acceptable magnetic field from our NDT Labs in Bangalore.

Tough to Remove Residual Magnetic Fields – How to Remove?

Demagnetization services Bangalore India

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.
 

How much is the Acceptable Residual Field ?

 
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.
 

Why de-magnetization ? – An Overview

 
For ferrous materials, Magnetic particle testing or magnaflux testing can detect flaws. For example,  Automobile Shafts, Rotors, Blades, Gears, Sprockets, weld joints, plates, and Aircraft components. To find surface and subsurface flaws, fatigue cracks during in-service inspection. However, some materials are easy to magnetize and easy to demagnetize. But, some retain large amount of residual magnetism that could be difficult to remove.
 

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

When is Demagnetization NOT Required ?

 
As demagnetization needs time, cost and affects the process, in certain cases, it is not required to perform the operation. If for any one or more of the following, answer is ‘Yes’ then you need not demagnetize the components.
 
  • 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

Measure Magnetic field post Demagnetization

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.
