Two of the most common welding processes used in fabrication are TIG welding and MIG welding.
Both methods create strong welds, but they differ significantly in terms of equipment, technique, and applications.
Professionals comparing the two processes often begin by reviewing available TIG welders used for precision welding applications.
What Is MIG Welding?
MIG welding uses a continuously fed wire electrode and shielding gas.
Advantages include:
-
faster welding speeds
-
easier learning curve
-
higher productivity for thick materials
What Is TIG Welding?
TIG welding uses a tungsten electrode and separate filler rod.
Advantages include:
-
greater precision
-
cleaner weld appearance
-
better control on thin metals
