In the welding world, the terms MIG and TIG are heard frequently. That's because these two types of welding have been used for both household and industrial applications for more than 50 years. While these welding processes are similar, there are some distinguishing differences you should know, as well.
The Basics of Welding
In MIG and TIG welding, an electrical arc is used that creates the proper amount of heat. The heat makes the weld pool in the parent metals being used. At this point, filler metal will be used to connect (weld) the parent metals to each other.
That's one similarity in the process. Another is that shielding gas is used to help protect the heated zone and minimize contaminants' presence. Even though the very basics of MIG and TIG welding are similar, the processes have unique elements that differentiate them from one another.
The Main Differences in MIG and TIG Welding
When it comes to the differences in MIG and TIG welding, one of the main ones is the names.
MIG Welding
MIG stands for Metal Intert Gas. This type of welding uses consumable wires that serve as the electrode and that are sent through the welding gun. At this point, it is consumed to build up the weld easily and quickly. Carbon dioxide is the common way the weld is shielded. This is a more affordable option than the other gases that are used for this.
TIG Welding
TIG stands for Tungsten Inert Gas welding. A tungsten electrode is attached to a welding gun via a collet with this method. With TIG welding, the electrode that is used isn't consumed. At this point, the welder can apply a filler metal separately, or they can complete the weld without the filler material. In TIG welding, the shielding gas that is used is usually argon. While this is true, it is also possible to use other gas mixes for certain types of metals.
MIG and TIG Welding Applications
It's possible to use MIG and TIG welding for household and industrial applications. While this is true, you will find that most welders prefer TIG welding when working with thinner metals or when more precise results are required. It is the most common welding method used for in marine, aerospace, and automotive applications. The most common metal used for TIG welding projects is aluminum.
With MIG welding, the process is used for mining and building applications, outdoor jobs, industrial projects, and pipe fitting.
Mobile Welding Solutions for Any Project
Working with a mobile welding service is highly recommended if you have a welding project or custom fabrication need. This allows the professional to come to your location and handle the job you need to be done. The welder can also determine what welding process (MIG or TIG) is best suited for the project to ensure that superior results are achieved for your project and welding needs.
