To TIG weld Aluminium, you will need a welding power source that has AC current. You can weld Aluminium on DC, but it won't work very well because of the oxide layer that forms on Aluminium. The AC part of the output breaks apart this layer allowing a clean weld. For starters when TIG welding you want to be using DCEN so the TIG torch goes into the Negative port (unless of course you have a machine that can switch the polarity internally) If you have the polarity around the wrong way as most people will default to having the torch in the positive output terminal your tungsten will burn up, and you will have trouble starting the arc when using High Frequency or HF for short.
You need a TIG torch preferably with a variable amp control or better still a foot pedal. Because Aluminium is a very good conductor of heat, the amps need to be reduced from the beginning where you need more amps to the end where you will need fewer amps. Without this amp control, Aluminium is very difficult to weld, and you will found your self blowing holes or not being able to get enough heat into the work pierce. The TIG torch should use a high flex cable and depending on the amps needed be a 9, 17 or 26 series or WP20 water-cooled. For thin sections up to 90 amps, a 9 series can be used up to 140 a 17 series can be used. If you are welding for long periods above these amps you will need either a 26 series or water-cooled torch otherwise it will get hot and burn out the flex head. There are workarounds such as letting the torch cool and not letting it get too hot this will prolong the life of it. The 26 series is a big torch and can be hard to use, especially when you are starting out. The 20 series water-cooled is the ultimate option as it allows welding up to 300 amps all day and it will not get hot along with being the same size as the 9 series head. However, the lead will have more weight in it than a 9/17 series flex cable. If you are starting out, we recommend using a 17 series this gives you a broad range of amperage and it nice and easy to control.
In one year alone, the world can produce 1,691.2 million tonnes of steel. While this doesn't even account for the majority of global metal output, it's enough to fuel pretty much every industry in Australia (and in the rest of the world as well.)
In making things out of metal and applying metals into various industries, welding is a necessary process for joining metals together. TIG welding is one of the most common controlled types of welding metals together in the world. Here, we're going to discuss what TIG welding is and how the process works as well as some applications for this process.

TIG welding is one of the most common controlled types of welding metals together in the world. Here, we're going to discuss what TIG welding is and how the process works as well as some applications for this process.
Tungsten Inert Gas (TIG) welding is the process of combining two metals by heating them with an arc of a tungsten electrode. Basically, it uses a non-consumable tungsten electrode to create the heat that's used to join two metal surfaces together.
TIG welding is generally used for thin sections of metal. It gives the operator more control over the welding process than other types of welding do, so it's ideal for thinner cuts that need extra care. It creates stronger welds than gas metal arc welding or shielded metal arc welding, so the completed projects are of a higher caliber.
The most common metals that are fused together by TIG welding are titanium, aluminium, and stainless steel. Most often, it's used on thin segments of stainless steel. This is how many metal objects and industrial machinery pieces are made. However, it also is often used to weld non-ferrous metals like copper alloys and magnesium.
Many industries use TIG welding when creating items from thin sheets of metal. The aerospace industry is one of the primary users of this process because it manufactures the inner workings of aircraft and vehicles that go into space, such as satellites. However, applications in transportation aren't limited to the air- TIG welding is also commonly used to create thin-wall tubing that can be applied to bicycles.
Performance car industries also make use of TIG welding. Car restoration and performance modifications are often done using these strategies. It also is used to build motorcycle frames and improve motorcycle's performance. When you need motorcycle restorations, TIG welding has you covered.
Additionally, industrial plant machinery is commonly made with TIG welding. Tools and dies in these facilities, especially components made of aluminium and magnesium, are created via this process. It holds together powerfully and is unlikely to break even when used often.
