What is TIG Welding?

TIG welding

TIG welding, or “Tungsten Inert Gas” welding, is a specialized welding technique that allows the technician to join metals with a high level of control. Tig welding can result in more precision than other welding processes like MIG (Metal Inert Gas) or shielded metal arc (Stick). During tig welding, the fabricator uses a tungsten electrode (the “tig torch”) to create the weld, while controlling the electrical arc with a foot pedal. They then use the opposite hand to feed in a filler metal rod into the weld to complete the adhesion.

What is Tig Welding Used For? 

Most commonly, tig welding is used for thinner pieces of stainless steel or non-ferrous metals and is appropriate for small, precise projects. Tig welding can be used in industries including:

– Aerospace

– Bikes and Motorcycles 

– Automobile 

– Electronics

– Robotics 

– Machine repair 

– Architecture 

– Furniture

The Differences Between Stick, MIG and TIG Welding 

Shielded Metal Arc Welding (Stick welding) is the simplest form and does not require a gas tank  or inert gases. It can be used for iron, steel, aluminum, and other alloys. MIG (Metal Inert Gas) welding requires the use of inert gas. During MIG welding, the fabricator runs the metal filler wire material through the torch (sometimes compared to a hot-glue gun). The gun then exerts inert gas to protect the welding puddle from other elements while the weld is formed. TIG welding uses gas and a separate metal filler rod, producing a more precise result with less splatter.

  • Stick Welding: Useful for larger projects in hard-to-reach locations. Less time-consuming. Less precise. 

 

  • MIG Welding: Fast, strong, and efficient. Allows more control than Stick. Requires use of inert gas and knowledge of feeding wire. Commonly used in large-scale production.

 

  • TIG Welding: Complex, detailed, produces a refined result. Requires more skill and knowledge. Less splatter, better visual results. Commonly used in fine, detailed production.

Is TIG Welding More Expensive? 

Since TIG welding projects are time-consuming and require a higher level of skill, it can be more expensive than other welding processes. However, going with a high quality TIG welder to get the job done correctly the first time can end up saving you money in the long term. Need a quote for your upcoming welding project?
