Ordinary welding wires are made to match a standard base metal
analysis. Most base metals are rolled, forged, or heat-treated, which
improves their physical properties. With ordinary electrodes, the
melting and resolidification process changes the deposit structure
completely from that of the base metal.
Magna alloys contain rare earth
compounds, special alloying elements, deoxidizers and stabilizers. These compensate for the transformation of the electrode composition
during the critical melting and resolidification phases.
