Aluminum alloy is one of the most widely used non-ferrous metal structure materials, which has been widely used in aviation, spaceflight, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for aluminum alloy welded structure is increasing, so the research on the welding of aluminum alloy will be further developed. At present, Al alloy is the most used alloy.
Melting and casting of Al alloy is the main link in casting production. Strict control of the whole process of melting and casting, the prevention of the pinhole, inclusion, less cast, crack, porosity and shrinkage and other casting defects plays an important role. Due to the large absorption of aluminum melt, oxidation ability, easy to dissolve iron, in the process of melting and casting process must take a simple and cautious preventive measures to obtain high quality castings.
All kinds of aircraft are the main structural materials of aluminum alloy. On the plane, the skin, rib, stringers, beam frame and landing gear can be made of aluminum alloy. The aircraft is used for different purposes, the amount of aluminum is not the same.
