Aluminum alloy is the most widely used non-ferrous metal structural material in industry, which has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, chemical industry and other industries. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing, which makes the research on aluminum alloy weldability deepen. At present, the most widely used alloy is aluminum alloy.

1808 alumina was electrolytically reduced to aluminum in the laboratory, and 1884 was used as the building material for the spire of the Washington Monument. Aluminum alloy materials synthesized by adding various metal elements into aluminum materials have been widely used in all aspects of the construction industry.

1908 Alcoa invented electrical aluminum alloy 1050 and made it into steel-core aluminum stranded wire, which pioneered high-voltage long-distance transmission.

19 15 Alcoa invented 20 17 alloy, and 1933 invented 2024 alloy, which greatly expanded the application of aluminum in aircraft. 1933, Alcoa Company invented 606 1 alloy, which initiated the quenching process of extruder and significantly expanded the application range of extruded profiles.

1943 Alcoa invented 6063 alloy and 7075 alloy, which opened a new era of high-strength aluminum alloy.

1965, Alcoa invented A356 casting aluminum alloy, which is a classic casting aluminum alloy.

With the in-depth research of aluminum alloy materials, high-strength aluminum alloys (2000 and 7000 series) have been widely valued by the global aviation industry because of their excellent comprehensive properties, and more than 80% of the structural quality has been used in commercial aircraft. Aluminum alloy has been gradually applied in life, military and scientific fields. ?
