To start, what is TIG welding gas? Well, TIG is short for tungsten inert gas. TIG welding involves using a tungsten electrode to send a current to your welding arc. While the current does its job, the tungsten and the puddle weld are kept safe with the help of an inert gas, which both protects and cools. TIG welding has been around since the 1930s and was used to keep aircraft together during the Second World War. It’s also worth knowing that TIG welding is often called GTAW, which stands for gas tungsten arc welding. So, what are the advantages of this 80-year-old technology?
1. More control
The best-known benefit of TIG welding is that, when compared with other methods, it puts a lot more control in the hands of the welder. By moving your foot, you can change amperage and heat levels quickly. So it’s perfect for working on complex, tricky details.
2. Less amperage
How is that an advantage? Well, a decreased amperage lets you work more easily on small and thin pieces of metal, which don’t respond very well to high levels of amperage.
3. Work with various metals
Being inert, TIG welding gas can be used on a variety of metals. If you’re working with copper or stainless steel, you should go for Argon or a mix with helium, but if it’s titanium you’re dealing with, make pure argon your choice. And what about aluminium and aluminium alloys? They love a blend of helium and argon.
4. Increased flexibility
Working on a project that involves a mix of small and large parts? With TIG welding gas, you can swap between the two without any hassle. It’s one of the most flexible welding techniques.
5. No slag!
Let’s face it, cleaning up slag is the least fun part of welding. When you’re using TIG welding gas, there’s no need to worry about that! TIG welding is incredibly clean and doesn’t leave a trace of slag in its aftermath.
