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.
