With tungsten inert gas (TIG) welding, metals are joined together by creating an arc between a tungsten electrode and the workpiece. The operator frequently feeds a filler rod into the weld pool to produce a weld.

TIG welding is regarded as the most difficult type of welding to learn since there is so much more possibility for error on the part of the welder.

A metal stick or rod is used as filler material during the electric arc welding method known as "stick welding." It's crucial to select the right kind of flux core wire welding rod for your application in order to produce high-strength welds.

Stick welding, like MIG welding, employs a DC or reverse polarity current to weld steel and iron.
