Abstract: The disclosed technology generally relates welding electrodes, and more particularly to consumable welding electrodes having functional coatings. In one aspect, a welding electrode comprises a core wire having a base metal composition and two or more coatings covering at least a portion of the core wire. The two or more coatings comprise an electrically conductive coating including one or more electrically conducting elements or compounds in addition to or other than copper (Cu). The two or more coatings additionally comprises an additional functional coating including one or more additional elements or compounds adapted to reduce friction of the welding electrode, stabilize an arc formed from the welding electrode, modify a microstructure of a weld metal formed from the welding electrode and/or modify a surface tension of a molten droplet formed from the welding electrode.
