Our de-magnetisation systems are used to eliminate arc blow, which can occur
when welding joint preparations are magnetic. We bring down magnetic levels to
a point at which welding can proceed.
|
Even when magnetic fields are weak in the steel, reducing face area can
concentrate magnetic flux, resulting in a joint preparation that can be several
hundred gauss. Fields of over 1000 gauss are
not uncommon.
Our technicians bring then field levels to below 10 gauss, even when residual
levels are over
1000 gauss.
