Welding is a skill that required, like anything, learning and practising till you master the skill. And learning how to weld aluminium can be a tricky skill depending on the processes used as well as the aluminium thickness. When it comes to welding with aluminium you have 3 basic methods, gas mig and tig welding. So having said that. Let’s take a look into the three processes of welding aluminium.
How to gas weld aluminium?
Gas welding is not that common although it can be found in several maintenance sectors like refrigeration repair. This involves the use of very thin aluminium sheets that are fused together.
By nature, the challenge with aluminium can be hard to determine the points where the metal will melt. That’s where the challenge lies with joining two parts of aluminium together. The metal can, what is called dropping out. It’s when their melting points are reached.
Aluminium welding is one that required that instinct knowledge that is developed through many hours of practice. It’s the knowledge of knowing when that melting point is near.
Welding alloys using a Mig Machine
When it comes to the best and easiest way to weld aluminium, this is the way to go. The beauty of mig welding is it uses a continuous wire feed if aluminium wire that’s applied to the weld area. Welding aluminium with a mig welder allows 1mm thick and upwards of metal. This can and does depend on the power of the mig welding machine. Thinner aluminium and you may need to spot weld. This will prevent blowing through.
This is something we are skilled at, so if you’re unsure about how to go about it yourself, we are here to help. At the end of the day, its what we do best. And it can be cheaper to hire us rather that hiring a welder yourself.
Sheet metals are most of the time welded using mig welders; common use is in aluminium boat construction, gates, fences and light structural work and architectural work.
Welding aluminium in heavy gauges is very similar to that of welding steel. You will need to change the welding cable liner to one made of Teflon that will allow for a smooth run of the filler wire.
Aluminium wire is a lot weaker than steel is and it requires a lot less friction with the cable and gun.
Welding alloy using a Tig welder.
When it comes to using a tig welder to weld aluminium, this also requires loads of practice, very similar to gas welding. Like gas, it requires the heating of the metals to their melting points with the use of a tig welding torch, then introducing a filler rod at the right moment. As you can understand, this also required a lot of skill and knowledge.
Some say this is the most satisfying welding visually.
Having said all that. Welding is our game and we know what is the best type of welding for the job. We are the welding Adelaide team that will get the job done right. Give us a call
