The granted patent (Publication Number: US11958140B2) discloses an aluminum welding alloy with specific composition requirements. The alloy includes magnesium, zinc, silicon, iron, copper, chromium, titanium, calcium, and/or strontium as surface active elements, along with optional arc stabilizer elements. The alloy is notably free of zirconium and demonstrates a welding efficiency of 82% or higher. The surface active elements are designed to have a lower vapor pressure than magnesium at elevated temperatures, enhancing the welding process.
Furthermore, the patent details the specific percentages of each element in the alloy, including manganese, magnesium, zinc, silicon, iron, copper, calcium, strontium, cerium, and lanthanum. The alloy is identified as a 5000-series aluminum alloy according to industry standards set by the Accrediting Standards Committee H35 of the Aluminum Association and the American Welding Society (AWS) A5.10 (2017). Additionally, the alloy can be classified as AA5356 or ER5554 aluminum alloy based on the same industry standards. The patent also covers the use of this aluminum welding alloy in the form of welding wire or welding electrode, emphasizing its applicability in various welding processes.
