Properties and Applications

Special coated electrode for aluminium-silicon and aluminium-magnesium-silicon castings. Suitable to use also in aluminium castings, containing up to 12% silicon. Used with DCEP. Hold the electrode perpendicularly to workpiece, with a short arc length, during welding. If the thickness is greater than 10 mm or in large workpieces, preheating shall be applied between 150°C to 250°C. Since slag residues are corrosive, they must be completely removed from the weld bead. Electrode serves well as consumable in oxyacetylene welding. The covering being hygroscopic, electrodes must be stored in an absolutely dry location, or redried if required.
