ALCORD 5Si is an electrode with a special coating for welding low-alloy Al-Mg-(Si) aluminium alloys and for joining dissimilar aluminium alloys.
When welding, hold the electrode at a right angle to the work piece surface and welding direction and keep the arc as short as possible.
Wall thicknesses greater than 10 mm and larger work pieces will require preheating from 150 °C to 250 °C.
This MMA electrode is also well suited for oxy-acetylene welding.
Slag residues are corrosive and must be completely removed from the weld bead.
The coating is highly hygroscopic, consequently electrodes must be stored in an absolutely dry location, or redried if required. The weight of the package is 2.0 kg.
