An electrode is a metal wire that is coated. It is made out of materials with a similar composition to the metal being welded. There are a variety of factors that go into choosing the right electrode for each project. SMAW or stick electrodes are consumable, meaning they become part of the weld, while TIG electrodes are non-consumable as they do not melt and become part of the weld, requiring the use of a welding rod.

The MIG welding electrode is a continuously fed wire referred to as wire. Electrode selection is critical to ease of cleanup, weld strength, bead quality and minimizing any spatter. Electrodes need to be stored in a moisture-free environment and carefully removed from any package When molten metal is exposed to air, it absorbs oxygen and nitrogen, and becomes brittle or is otherwise adversely affected.

A slag cover is needed to protect molten or solidifying weld metal from the atmosphere. This cover can be obtained from the electrode coating. The composition of the welding electrode coating determines its usability, as well as the composition of the deposited weld metal and the electrode specification. The formulation of welding electrode coatings is based on well-established principles of metallurgy, chemistry, and physics.

The coating protects the metal from damage, stabilizes the arc, and improves the weld in other ways, which include: Smooth weld metal surface with even edges, Minimum spatter adjacent to the weld, A stable welding arc, Penetration control, tough coating, Easier slag removal, the Improved deposition rate

Classification of welding electrodes

The metal-arc electrodes may be grouped and classified as bare or thinly coated electrodes, and shielded arc or heavy coated electrodes. The covered electrode is the most popular type of filler metal used in arc welding.

The composition of the electrode covering determines the usability of the electrode, the composition of the deposited weld metal, and the specification of the electrode. The type of electrode used depends on the specific properties required in the weld deposited. These include corrosion resistance, ductility, high tensile strength, the type of base metal to be welded, the position of the weld (flat, horizontal, vertical, or overhead); and the type of current and polarity required.
