TIG Welding 101
In this third article in our series we’ll cover TIG welding, which many people consider the most desirable of the welding processes.
TIG welding offers unsurpassed control, with the ability to weld virtually any metal, and it has the potential to make a weld with that prized “stack of dimes” look.
The downsides are that TIG welding equipment is more expensive, and the learning curve is steeper. Nevertheless, if your goal is to do work where the weld beads are featured as part of the design, or if you want to weld exotic materials, it could be worth the time and money it takes to develop proficiency with this process. TIG welding has particular benefits for sheetmetal work since the welds are small and relatively soft, making them easy to work with a hammer and dolly.
All welding processes are fundamentally methods for applying heat to the metals being joined in a controlled manner. TIG welding accomplishes this with a tightly focused electric arc, shielded from the atmosphere with an inert gas. The better TIG machines allow you to change the heat “on the fly”—either with a foot pedal or with a knob or slider on the torch body. This ability to make continual adjustments as you weld is one of the keys that make TIG welding so precise.
