DEMAGNETIZING PRIOR TO WELDING
The phenomenon of magnetic arc blow, well known to experts, results in deflection of the arc during welding. This phenomenon can already be observed with residual magnetism values of 10-20 A/cm, depending on the welding method used (WIG, MIG/MAG, etc.). With electron beam processes (EB welding, EB hardening), very low levels of residual magnetism also influence the precise direction of the electron beam. Thus the components to be welded, as well as the tool holders, have to be demagnetized to the lowest possible value. Maurer Magnetic offers a broad range of products for industrial customers – for mass production, for individual manual applications and for emergencies (e.g. standstills at construction sites due to welding problems).
