Information
ESAB OK Autrod 4043 Aluminium Mig welding wire with 5% silicon. 4043 grade
Formerly known as OK Autrod 18.04
Available online in 1mm and 1.2mm diameters

OK Autrod 4043 is one of the most widely used welding and brazing alloys and can be classified as a general-purpose filler alloy. The silicon addition results in improved fluidity (wetting action), making the alloy the preferred choice of welders. The alloy is not sensitive to weld cracking and produces bright, almost smut-free welds. Not recommended for anodising. Non-heat treatable.

Successful welding of aluminium starts with the selection of the best available consumable to obtain X-Ray quality welds and to avoid feeding irregularities that can lead to costly downtime and weld rejects. At ESAB, consumable production starts with the selection of raw materials with the lowest possible content of hydrogen; the principal source of porosity.

In Production, ESAB apply a unique shaving process to remove the oxide skin and produce a surface free from abnormalities that can trap contaminants that cause porosity. Finally, a special surface finish with a microscopically thin layer of patented hydrogen-free lubricant provides superior feeding and reduced fume.

The unique properties make ESAB aluminium products also very suited for porosity sensitive processes such as laser beam welding or electron beam welding.

As the world’s biggest aluminium welding wire manufacturer, ESAB leads the development of productive, high quality MIG wires and TIG rods and offers the most comprehensive product range. With ESAB, fabricators can rely on the unique support from a welding consumables and equipment manufacturer with worldwide process and applications experience and a global presence.
