Shielded Metal Arc Welding, commonly called Stick welding.
A shielded electrode passes a current between itself and the workpiece.
Both the base-metal and the electrode are melted by the current and the electrode is consumed and deposited into the melted puddle forming the weldment.

The main difference between these two types of welding is that GTAW uses gases to create the weld whilst SMAW uses an an electrical current. Both are very popular welding processes.
Advantage of smaw :*equipment is relatively inexpensive Equipment is portable because the welding machine can be powered with gasoline or diesel powered w/ engines.
