Description
Electrode for welding forged and cast aluminum-magnesium alloys and aluminum-manganese alloys
Electrode developed for welding forged and cast aluminum-magnesium alloys and aluminum-manganese alloys. When welding, hold the electrode at a right angle to the workpiece, with a short arc.
Wall thicknesses greater than 10 mm and larger workpieces will require preheating from
150°C to 250 °C. Since slag residues are corrosive, they must be completely removed from the weld bead. It displays good weldability and no porosity.
