Recently, Goudsmit demagnetization expert Ger recently demagnetized a helipad in Germany. This was necessary because the compasses of helicopters on the current 30 platforms are affected by the magnetization of gutter covers, rails, and reinforcing steel. The helicopter compasses deviated significantly. The magnetic force was caused by a magnetic sweeper designed to remove iron particles from the platform, but which inadvertently magnetized all steel components. During this process, after some tests, the idea of a new application for a demagnetization tunnel was proposed.

Demagnetization issues

The experts attempted to demagnetize the gutter covers and railings in the concrete deck. To do this, they placed the cables of a mobile demagnetization device on the steel components and attempted to demagnetize them using controlled AC current. This was insufficient to reduce the unwanted magnetism to an acceptable level. Subsequently, they wound the cables around the plates and dragged the structure across the entire platform to reach the reinforcing steel bars below the surface. The results were better, but still inadequate.

Solution

The demagnetization experts continued to search for a solution. Finally, they placed a demagnetization tunnel on its side and installed wheels underneath it. Thus, the tunnel functioned as a demagnetizing sweeper. The high power of the tunnel, combined with controlled AC current, ensured that the magnetic values in the platform reached an acceptable level and no longer affected the compasses. This approach resulted in a completely new product, which helicopter manufacturers immediately purchased and applied to other 29 platforms.

The new demagnetization system is also suitable for large steel plates measuring 12 x 4 meters, such as those used for offshore wind turbine foundations. Magnetism in the plates affected the welding process.

For complex or very large products that are difficult to disassemble or transport, our on-site service is a reliable solution. Demagnetization experts from Goudsmit will bring mobile demagnetization equipment to your location and resolve your issues on site. Examples include: demagnetizing (oil) pipelines, demagnetizing large shafts or buildings, and creating temporary fields to simplify the welding of magnetic parts.

For occasional demagnetization,Goudsmityour parts can be demagnetized at our factory. This saves you cost and space. For this purpose, we have demagnetization equipment and a professional team with extensive experience in demagnetizing challenging products. Examples include: demagnetizing tools or dies; demagnetizing shafts, pipes, lathes, and milling tools with excessive magnetism that prevents welding; and demagnetizing (precision) parts where magnetism is prohibited, such as piston rings, razor heads, camshafts, saw blades, etc. Our demagnetization experts are equipped with a gaussmeter to measure magnetic flux density on site and determine whether demagnetization will achieve the desired result.
