Important Things to Know about TIG Welding

If your business requires welding, a few different welding methods may need to be used. For example, TIG welding is only used in certain situations, and there are several factors to take into consideration when deciding whether or not to use this particular method.


First of all, TIG stands for tungsten inert gas and can as be referred to as GTAW or gas tungsten arc welding. In order to weld, an arc is created by a constant flow of electricity. This arc is then shielded by an inert gas, like helium or argon. Intense heat is applied to both the metal and the rod to form a tight weld. It is particularly effective for thinner sheets of metal, such as:

  • Stainless steel
  • Aluminum
  • Bronze
  • Magnesium

Furthermore, GTAW is a better alternative to torch welding because it doesn’t require as much expertise. However, it still takes considerable skill and knowledge to weld properly. GTAW also tends to be effective because the electric arc provides better control over the process than a torch. But since there are so many different options, it takes a considerable amount of practice and training to get it right.


It’s important to know all parts of the unit. During the welding process the following should be used:

  • Work lead
  • Lead cable
  • TIG torch
  • Gas line
  • Gas bottle with a regulator


Cleanliness is absolutely essential if you want to create the strongest possible weld. A special brush should be used on aluminum and not for any other metals. It is best to keep one brush for stainless steel and another for aluminum, and it is especially important not to use brushes that were previously used on rusty steel or iron.


This is a common mistake and can be extremely frustrating. Once the tungsten enters the puddle, it becomes contaminated and the process needs to be stopped. In order to restart the entire process, the arc assembly must be dismantled, and the tungsten must be grinded down. If the welding process is not stopped, the arc will not stay in one place during the weld.


Because TIG welding requires special equipment, training, practice, and knowhow, a professional fabrication company should be considered. They will not only save you a great deal of time and headaches, but they can also increase your shop efficiency.
