TIG welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert gas shield.
The TIG welding process is relatively complex and requires a high degree of skill and experience to master. However, once mastered, it can produce extremely high-quality welds.
A wide range of metals can be welded with TIG welding, including carbon steels, titanium, alloyed stainless steels, low-alloy steels, copper, nickel alloys, aluminium, magnesium, and other nonferrous alloys. TIG welding is particularly suitable for metals of only a few millimeters of thickness due to its use of an infusible electrode. It is commonly used in the aviation, sheet metal and aerospace industries and for general fabrication and repair work.
If you are looking for a welding process that can provide you with high-quality welds, then TIG welding may be the right choice for you. National Welding Supplies may be your best resource for advice on the best options for welding.
How to Choose a Tig Welder?
When you’re in the market for a Tig welder, there are a few key features to look for that will ensure you get a machine that’s right for your needs.
Consider pulsed welding – this feature allows you to make much cleaner welds by reducing heat input and is ideal for delicate work.
If you need to move your welder around the workshop or take it with you to job sites, then portability is an important consideration. A welder with wheels and a handle can be easily moved from one location to another and is much less likely to sustain damage in transit.
A foot pedal is a handy addition to any Tig welder, as it gives you greater control over the welding process. This means you can weld for longer periods without getting tired and avoid making mistakes that could ruin your work.
You don’t want a welder that’s difficult to operate – look for models with simple controls that are easy to understand and use.
Plasma Cutter/ Stick Welding Options
If you need to use a plasma cutter or stick welder as well as a Tig welder, then consider models that offer these options. This will save you money in the long run, as you won’t need to buy separate machines for each task.
A good Tig welder will have a stable, high-quality arc that produces consistent results. This is particularly important if you’re working with thin materials, as a poor quality arc can cause the material to overheat and warp.
Some welders have high-frequency settings that can be used to reduce the amount of time it takes to weld. This is useful if you’re working on a tight deadline, as it can help you get the job done faster.
To sum up, when choosing a TIG welder, it’s important to look for machines that offer features like pulsed welding, portability, simple controls and a high-quality arc. If you need to use other welding processes as well, then it’s also worth considering models that offer plasma cutting and stick welding options.
