TIG welding (Tungsten Inert Gas welding) is one of the most precise welding processes used in fabrication today.
It is widely used for stainless steel, aluminum, and specialty metals that require clean, high-quality welds.
Professionals looking to purchase equipment often begin by reviewing available TIG welders designed for precision welding.
How TIG Welding Works
TIG welding uses a non-consumable tungsten electrode to create the welding arc.
Shielding gas protects the weld pool from contamination while the welder manually feeds filler rod into the weld.
This level of control makes TIG welding ideal for:
-
aerospace components
-
motorsports fabrication
-
stainless steel piping
-
aluminum welding
Equipment Used in TIG Welding
A typical TIG welding setup includes:
-
TIG welding machine
-
TIG torch
-
tungsten electrode
-
filler rod
-
shielding gas
Many fabricators prefer Lincoln Electric TIG welders due to their arc stability and advanced AC/DC welding capabilities.
TIG vs Other Welding Processes
TIG welding is commonly compared with MIG welding.
MIG welding offers faster production speeds, while TIG welding provides greater precision and cleaner welds.
If you’re comparing the two processes, read our guide to TIG vs MIG welding.
AC vs DC TIG Welding
Another important concept is understanding when to use AC versus DC welding modes.
AC is typically used for aluminum, while DC is used for steel and stainless.
