Though similar in the name, TIG and MIG welding have quite a few differences.  So how do you choose the right welding process for your facility? Well, before we get into the advantages and disadvantages of each welding process, let's discuss what these process are:

MIG welding, or Metal Inert Gas welding, combines two pieces of metal together with a consumable wire connected to an electrode current. A wire passes through the welding gun at the same time as the inert gas. The inert gas protects the electrode from contaminants.

TIG welding, also known as Tungsten Inert Gas welding, uses nonconsumable tungsten, along with an inert gas, to weld two work pieces together. The tungsten electrode provides the electricity, but not the filler, for the welding process. While it can use filler, it sometimes creates a weld where one part melts into another.

Deciding which one is suitable for your company depends on the precision of weld required, time allocated for setup, utilization and initial cost. There are several benefits and fallbacks to using TIG and MIG welding, depending on your facility's needs.

Advantages and Disadvantages of MIG Welding:


  • Quick - MIG welding is known for its quickness in producing welds. 
  • User-Friendly - These welds tend to be more forgiving and are easier to make.  Setup takes less time and is easy to automate.
  • Price - Equipment is more accessible and costs less for MIG welding.  


  • Reliability - Less stable arc, some irregular wire feedback and burnback can occur with MIG welding.
  • Dirtier - More sparks, fumes and smoke are produced during this welding process.

Advantages and Disadvantages of TIG Welding


  • Cleaner - Using Tungsten to provide its electrical current, TIG welding decreases the amount of sparks, smoke and fumes produced. 
  • Precision - TIG welding has less contamination in its weld, providing more precise and higher quality welds.
  • Autogenous Welds - These welds do not require a filler material to be used.  TIG welding can create a weld by melting one part to the other.  Autogenous welds are most commonly used when welding thinner materials.


  • Setup - TIG welding requires more setup time and is not as user-friendly. 
  • Price - These welds tend to be more expensive and take longer than MIG welding, especially in thicker metals.
  • Complexity - TIG welding is more complex and requires more skill than the MIG welding process.
