What Is Difference Between Mig And Tig Welding?

Are you confused between choosing the right welding process, MIG or TIG? Well, if you are, you’re in the right place! This article aims to clear up the confusion between the two processes and provide you with a clear understanding of the difference between the two.

With more than 85% of the welding processes carried out in the North America using MIG and TIG, understanding their difference is important. This article will tell you the pros and cons of both the processes, the important types of welds associated with them, as well as other information.

So, let’s dive in and understand what is difference between mig and tig welding?

What is difference between MIG and TIG welding?

Welding is a necessary process to join two pieces of metal or plastic together. MIG and TIG welding are two of the more popular types of welding processes and can be used for a wide variety of applications.

Both are effective, but it’s important to understand what their differences are so that you can select the most appropriate type for any particular job.

What is MIG welding?

MIG (Metal Inert Gas) welding is one of the easier welding processes to learn and use, especially when welding steel and aluminum with a steel alloy wire. This process is also known as Gas Metal Arc Welding (GMAW). In MIG welding, the welding arc is formed between a wire electrode and the material that is being welded which melts, fuses the base and the filler materials together.

A constant voltage source supplies steady current to the welding gun. You can easily control the joint size and the welding speed by adjusting the wire feed speed.

What is TIG welding?

TIG (Tungsten Inert Gas) welding is also known as Gas Tungsten Arc Welding (GTAW).

In this process, an arc is created between a non-consumable tungsten electrode and the work piece being welded. The arc is maintained between the two pieces of material being welded and a filler material is added manually as needed. TIG welding is a more difficult process to learn and use, due to the complexity of the setup and the need for manual filler material addition.

It’s a slower process than MIG but produces more consistent, quality welds and can be used for a variety of materials and alloys.

Difference between MIG and TIG

  • MIG welding is easier to learn and generally easier to use than TIG welding.
  • MIG welding is faster than TIG welding.
  • MIG welding can be used to weld a variety of metals such as steel and aluminum, while TIG welding is best suited for thin metals.
  • MIG welding requires a shielding gas to protect the weld area, while TIG welding does not.
  • TIG welding produces higher quality welds than MIG welding.
  • TIG welding is generally more expensive than MIG welding.
In conclusion, both MIG and TIG welding provide effective ways to weld two pieces of metal together, however, each type of welding has its own unique advantages and disadvantages. When selecting the welding process you need for a particular project, it’s important to consider the type of material, the desired quality of the weld, the speed of the welding process, and the complexity of the setup and process.
