[0002] Aluminum alloy is the most widely used type of nonferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing, which has led to in-depth research on the weldability of aluminum alloy. At present, aluminum alloy is the most widely used alloy.

[0003] Aluminum alloy has low density but high strength, close to or exceeding high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry, second only to steel in usage. Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: melting, extrusion and coloring. Among them, coloring mainly includes oxidation, electrophoretic coating, fluorocarbon spraying, wood grain transfer and other processes.

[0004] At present, aluminum profiles in the market often need to be refined and cast before finishing to remove impurities in the aluminum.
