A component of the welding circuit through which current is conducted and that terminates at the arc, molten conductive slag, or base metal. See ARCWELDING ELECTRODE, CARBON ELECTRODE, COVERED ELECTRODE, ELECTROSLAG WELDING ELECTRODE, FLUX CORED ELECTRODE, METAL CORED ELECTRODE, METAL ELECTRODE, RESISTANCE WELDING ELECTRODE, and TUNGSTEN ELECTRODE.

Electrodes used for welding carbon steels and alloy steels have been standardized by the specifications of the American Welding Society. ANSIJAWS A5.1, Specification for Carbon Steel Electrodes for Shielded Metal Arc Welding covers electrodes for welding mild steel. Low-alloy steels appear under ANSUAWS A5.5, Specification for Low Alloy Steel Covered Arc Welding Electrodes.

ANSUAWS A5.4, Specification for Stainless Steel Welding Electrodes for Shielded Metal Arc Welding covers stainless steel arc welding electrodes with various nickel and chromium contents. See STEEL, STAINLESS, Arc Welding.

Copper and copper bearing alloy arc welding electrodes appear under ANSUAWS A5.7, Specification for Copper and Copper Alloy Bare Welding Rods and Electrodes. See COPPER ALLOY WELDING.

Aluminum arc welding electrodes appear under ANSIIAWS A5.3, Specification for Aluminum and Aluminum Alloy Electrodes for Shielded Metal Arc Welding. See ALUMINUM. See also ELECTRODES.
