What Are The Different Types of Welding Electrodes
Consumable electrodes are actually consumed or used in the welding process. The melted electrode becomes part of the final weld. Both stick welding (SMAWshield metal arc welding) and MIG (gas metal arc welding) use consumable electrodes as they both add filler metal to the joint. Non-Consumable electrodes remain intact through the welding

Shielded metal arc welding / SMAW uses a 14" consumable electrode that conducts the current to the weld puddle. As the arc melts the end of the electrode it becomes part of the weld metal. The arc also vaporizes the Flux that coats the electrode to create a gaseous shielding cloud to protect the molten weld puddle from atmosphere contaminates.

PPT Introduction to (SMAW) Shielded Metal Arc Welding
Shielded metal arc welding (SMAW) is often referred to as stick welding. This welding process can use either alternating current (AC) or direct current (DC). The electrodes (rods) that are used have a coating called flux. During the welding process the flux forms a gas shield that protects the weld puddle from atmospheric contamination.
