NIKKO STEEL Welding Electrode

Manufactured using a fully alloyed core wire, the chemically basic flux which contains a high proportion of chlorides and fluorides using a silicate with a high molecular ratio of silica to sodium oxide. The flux, as well as providing a shielding gas, also produces a slag with a vigorous cleaning action.

The electrode is suitable for use on DC+ only. Aluminium has a low melting point, therefore the electrode burn-off rate is considerably higher than all other electrodes, thus necessitating high travel speeds. As the alloy is non-heat-treatable, it will only match the properties of cast alloys.

May be used for rectification of casting defects, particularly those present at the surface. Also for welding cast aluminium components which have become worn or damaged in service. May also be used for cosmetic repairs on similarly alloyed wrought components. The weld metal conforms to aluminium association designation cast alloys A43 or 43.
