    Abstract: Al—Mg and Al—Mg—Zn weld filler alloy compositions for use with fusion weldable 7xxx, 6xxx, 5xxx and 2xxx series aluminum alloy base metals are disclosed. The weld filler alloys may be used for joining a first aluminum base metal segment to a second aluminum base metal segment, where the base metal segments is at least one of 7xxx, 6xxx, 5xxx and 2xxx series aluminum alloy. The weld filler alloys, in wire or rod form, may also be used to repair a defective weld.
