How To Tig Weld


Learning how to tig weld is similar in a way to oxy-acetylene welding. The work area to be welded is first heated to the point where fusion between the two parts can occur and a filler rod is introduced to help in the process. While on thinner sheet metals a skilled tig welder can fuse the parts together without a filler rod, a filler material is needed in most applications to build up the weld and give strength to the weld.

How to tig weld involves using a specialized welding torch that utilizes a tungsten electrode to create the arc. This electrode remains intact during the process and is held above the part to be welded just far enough to create an electric arc, about 5 to 10 mm. This arc heats and fuses the parts to be joined and also melts the filler material into the weld.


Tig welding requires more skill from the operator than it does for using mig welders or an arc welder. To use a tig welder the operator must manipulate the welding torch in one hand to control the length and size of the welding pool, to which the filler welding rod is added to the joint as needed using the other hand.


The tig welding process is much slower than mig welding and arc welding, and learning how to mig weld is an easier process. The advantage  however is that the finish from manual tig welding is far superior and is perfect for welds on equipment and parts such stainless steel marine fittings, high performance bicycles and in the food manufacturing industries. These welds are visually appealing, strong, pure and require little or no clean up.


Tig welding machines are specialized welding equipment and can be used for welding mild steel, aluminum, stainless steel, brass and bronze, cast iron and precious metals such as gold, silver and titanium.
