TIG Welding

In the Tungsten inert gas (TIG) welding process, an essentially non- consumable tungsten electrode is used to provide an electric arc for welding. A sheath of inert gas surrounds the electrode, the arc, and the area to be welded. This gas shielding process prevents any oxidization of the weld and allows for the production of neat, clean welds.

TIG welding can be performed with a large variety of metals. The two most commonly TIG welded metals is the PRL are steel and aluminum. Steel is relatively easy to TIG weld and it is possible to produce very tight, neat welds. Aluminum takes a little more skill, and one should have at least a little bit of experience in welding steel before making the transition to aluminum. However, the basic technique is essentially the same and most people can make the jump to aluminum fairly easily.

TIG welding is an extremely powerful tool. With a little practice, it is possible to make beautiful welds much more quickly and easily than oxy- acetylene welding. It’s also the only option currently used in the shop for welding aluminum. Put in a little time and you will be rewarded in spades.
