Description
Specially coated electrode for welding pure aluminum. The INTERALU AL-100 electrode is preferably used in the horizontal position. The weld metal has good color matching with the base metal and high electrical conductivity. Keep the electrode vertical to the workpiece with a short arc length during welding. For thicknesses over 8 mm or large workpieces, preheating should be applied between 150 °C and 250 °C. During welding, electrode oscillation should be avoided. Slag residues must be removed to prevent potential weld corrosion. As the coating is highly hygroscopic, electrodes should be stored in a dry place.
