Electrode Coating
The mixture of chemicals, minerals and metallic alloys applied to the core wire. The coating controls the welding current, the welding position, and provides a shielding atmosphere, deoxidizers to clean the weld metal, and the welding slag that absorbs impurities from the weld metal. It also helps shape the weld bead and becomes an insulating blanket over the weld bead.
