ALUMINIUM MIG WIRE

MIG welding aluminium is trickier than welding mild steel.  Aluminium conducts heat very well as well as having a low melting point.  These characteristics make it difficult to achieve good penetration without blowing holes in the work piece, particularly in thinner sheet metal.

With that said, MIG is best used on thicker Aluminium and actually welds very nicely with the MIG process.  Welding anything other than flat position or thin materials takes a skilful hand.

If Aluminium MIG welding frequently, pulsed MIG is a good option.  It offers the best of both worlds – attractive looking welds and increased productivity.  Pulsed MIG welders switch from a high peak current to a low background current many times per second.  In doing so, heat onto the material is minimised which helps to prevent warping and burn through of the aluminium.  The switch between higher and lower currents also acts to detach droplets of the aluminium MIG wire electrode , depositing into the weld puddle and effectively mimicking spray transfer.

Which MIG Wire?

Generally, the most common aluminium MIG wires are 4043 and 5356.

4043 – An aluminium alloy with 5% silicon giving excellent flow characteristics and penetration.  Suitable for most grades of Aluminium, bot not suitable for marine grade or when post process anodising is going to be done.

5356 – A general purpose solid aluminium wire with 5% magnesium that has excellent corrosion resistance and high strength.  Suitable for welding magnesium bearing aluminium alloys such as 5251 (N4), 5154 (N5), 5454 (N51) and also heat treatable alloys 6063 (H9), 6061 (H20) and 6082 (H30). Also suitable for welding forged and cast aluminium-manganese / aluminium-magnesium components, and dissimilar aluminium alloy grades containing a maximum of 5% Mg. Can also be used to weld components which are to be subsequently anodised

5356 aluminium MIG wire is much stiffer then the 4043 wire. The stiffer properties of 5356 MIG wire tends to lead to less problems associated with wire feeding of aluminium wires.

Aluminium MIG Welder Accessories

Spool guns

A spool MIG torch contains a small spool of MIG wire within the torch itself.  This is particularly beneficial when using very thin diameter aluminium MIG wire which would be prone to wire feed problems through the liner to the MIG torch.

Spool guns are suited to small welding projects given the small wire spools it takes.  Its the most trouble free wire feed system and is also a good option for out of position welding.

Push-Pull torches

Push pull torches contain a small motor which runs rollers much like that found in a MIG wire feed unit.  The rollers in the push-pull torch act to assist in pulling the MIG wire through the liner, into the torch and through the contact tip.  Popular in production welding, these torches allow the use of standard MIG wire spools (housed inside the welder as normal).  Slightly tricky to set up, but very little downtime once up and running.
