You’ll find during a job search that there are MIG welding jobs and TIG welding jobs. What’s the difference? These two types of welding can be seen as a specialization. While they are both used often in the field, the main difference is the way in which the metal used during the welding process is fed.
MIG welding uses a process where wire is continuously fed to the welder. In terms of sophistication and complexity, MIG welding is far easier than its TIG counterpart.
Welding wire is continuously fed from a spool while burning, melting and eventually fusing together with the base and parent metals. There are a variety of metals that can be used in MIG welding jobs, including:
- Stainless steel
Thickness levels can vary depending on the requirements of the job.
The TIG process uses welding rods that are slowly fed into what is called a welding puddle. This process is used with thinner gauge materials and is more complex. TIG welding would be used with thinner metals, such as those seen on a kitchen sink.
In terms of power, the welder has far better control with TIG welding. While a welder will normally deal with thinner metals, there is the possibility of pipe welding or doing heavier tasks with the TIG method. A more powerful unit will be necessary to handle heavier welding jobs, such as pipe welding.
In terms of speed, TIG is slower than MIG, but this is not a bad thing. Versatility is always higher with TIG because of the slow feeding of metals. Welders will often switch between the two welding processes, depending on the job. A person would not want to perform regular, at-home welding with the TIG method because it is simply too slow and tedious.
