Abstract
The disclosed technology relates generally to welding, and more particularly to consumable electrodes based on aluminum. In one aspect, a consumable welding electrode comprises a base metal composition comprising magnesium (Mg) and at least 70% by weight of aluminum (Al), and a smut-suppressing metal. A standard free energy change (?G°) of formation of a smut-suppressing oxide by oxidation of the smut-suppressing metal under equilibrium conditions at a temperature of 1600K or higher is more negative than a ?G° of formation of MgO by oxidation of Mg, such that the smut-suppressing metal is configured to form the smut-suppressing oxide that is thermodynamically more favored over MgO on a surface of a weld metal formed from the consumable welding electrode. The smut-suppressing metal is present in an amount of 0.05-0.50% by weight of the consumable welding electrode.
