Basic Flux Coated Aluminium-12 Silicon Electrode For Welding Non Heat-Treatable Aluminium Alloys Containing Up To 12% Si
ALUMIN 12
CLASSIFICATION
DIN 1732 EL-AISi12
PRODUCT DESCRIPTION
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.
WELDING FEATURES OF THE ELECTRODE
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
APPLICATIONS AND MATERIALS TO BE WELDED
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 aluminium association designations for 12% Si aluminium includes 13, A13, B13 and 3S4.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 60oC for 30 minutes.
