The chemical activity of aluminum and its alloys is very strong, and it is easy to form a refractory oxide film on the surface. In addition, aluminum and its alloys have strong thermal conductivity, which may cause non-fusion during welding. At the same time, the oxide film can absorb more water and become one of the important reasons for the pores in the weld.The adding of the different alloy elements such as Cu, Mn, Si, Mg, Zn also has different effects on the
aluminum alloy’s welding performance. Of the different alloys, the welding 3003-h14 aluminum is of excellent welding property.3003 h14 aluminum is a typical Al-Mn alloy, with good formability, very good corrosion resistance and weldability. The strength is about 10% higher than 1100. Its welding is readily accomplished by means of conventional welding methods including gas, electric and resistance welding. GMAW and GTAW are preferred and widely used to produce structural welds.It may be gummy if machined. Soldering is limited to the torch method. Welding of strain hardened tempers will reduce strengths in the heat affected zones. The filler rod is generally 1100
aluminum alloy. When welding 3003
aluminum sheet to other
aluminum alloys, such as 5052, 6061 or 6062, the filler rod should be 4043 alloy.Since 3003 h14 aluminum is of excellent welding property, it is often used for the welding parts for ships, vehicles and aircraft plates. In addition, used in ductwork, chemical equipment, and general sheet metal work. It is also used to make cooking utensils, storage tanks, pressure vessels.
