Abstract: A method of welding galvanized steel with a high energy density beam is disclosed. The high energy density can be created by an electron or laser beam with a power density of at least 4 X 106 watts per square inch. A flux material, such as iron oxide, is disposed adjacent the welding zone, preferably by painting thereon, which is effective to from a compound with the zinc of the galvanized steel upon heating. The compound has a vapor pressure substantially the same or lower than the vapor pressure of the steel substrate so that disruption of the weld puddle is prevented to insure that all of the weld puddle will be available to properly close the weld void.
