The type of weld you use will depend on the project

MIG Welding

MIG welding is actually a type of Arc welding. MIG welding uses a small wire fed through a tube or gun that gets welded to the metal as the tube feeds out the wire. MIG welding is often praised for being faster, cheaper and easier to use than TIG welding. It's commonly used for automotive welding and DIY at-home projects.

TIG Welding

According to the Welding Robots website, TIG welding is the primary method used within the aerospace industry. While TIG is typically more costly, time consuming and difficult, it produces high-quality welds. TIG welding requires the use of both hands and one foot to operate a foot pedal.

Bottom Line

TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.
