3. TIG, or Gas Tungsten Arc Welding (GTAW)
As opposed to MIG welding, TIG is a complicated welding method reserved for experienced and skilled welders
. With TIG welding, the electrode is made of tungsten and is non-consumable. It is unique in that it can be done without filler metal, using only the two metals being welded together. You can add a filler metal if you feed it by hand.
You'll need a shielding gas tank to protect the weld, meaning TIG is typically preferable for indoor welding. Because there is no weld spatter with TIG, no cleanup is necessary, and the welds tend to be attractive. And although the welding method is versatile and precise, it is one of the most challenging techniques to learn.
TIG requires two hands when using a filler: One holds the TIG torch, and the other feeds the filler rod. This torch creates heat and arc to weld metals, such as steel, nickel alloys, stainless steel, aluminum, titanium, and others.
TIG is commonly used when welding small, thin items that require a stylish appearance. It's also preferred for DIY projects like repairing lawnmowers, making furniture, fixing bike frames, and building metal shelving.
