Mechanical properties, typical as weld Mechanical properties of the deposited metal are determined by the dilution with the base material. Gas Temp. Condition Yield Strength 0,2% Tensile Strength Elongation Values acc. to DIN 1732-3 I1 20ºC As welded ≥ 120 N/mm2 ≥ 250 N/mm2 ≥ 18% Usual base materials to be welded Suitable for cast aluminium welding and cast aluminium welding when joining products of the series 3000, 5000, 6000, 7000. Products of series 3000, 5000, 6000. Packaging Product Size (Ø mm) Plastic spools, Baskets and Drums GMAW 1-1.20 – 1. 60 GTAW 2.4-3.2 Almacenamiento Keep protected from humidity and dirt. Once the package is opened, and in case of not using all the material, keep into its original case closed and preferably in a heated cabinet, at least at 20°C. Keep the label of the spool (GMAW) or wrapping (GTAW). Before welding Remove the alumina layer and dirt (grease, dust…) as well as humidity from the welding area mechanically or by brushing it with stainless steel spikes. Do not use lubricant that contains diluted oils in the joints. Welding equipment When welding GMAW, conducts (liners, etc.) and pushing rollers have to be suitable for aluminum and be kept clean. Do not hit the gas outlet nozzle.
