[China Aluminum Industry Network] 1. Mechanical Connection Technology Aluminum alloys have high thermal conductivity and use traditional resistance spot welding technology to connect with extremely high energy consumption and the quality is difficult to guarantee. At present, foreign automakers use a large number of mechanical connection methods such as self-piercing riveting and self-cutting screws to achieve aluminum alloy connections. This technology is currently monopolized by foreign companies such as Henrob of the United Kingdom, Emhart of the United States, and Bolhloff of Germany. China needs to independently develop mechanically connected equipment and processes with independent intellectual property rights through independent innovation to break foreign technical barriers.
2. Welding technology For the connection technology of aluminum body parts, in addition to a large number of non-melting connection methods such as lock riveting, self-cutting screws, self-tapping screws, punching process, and glue (sticking) connection, MIG welding is also widely used. Laser welding (including laser welding, laser brazing) and laser-MIG arc welding. Among them, MIG welding, laser welding, laser-MIG arc welding, and friction stir welding have become standard processes for welding aluminum body parts. The highlight of BenzSL, the European body-in-white championship in 2012, is the first time that friction stir welding has been used in a large number of applications. The total number of vehicle body welds is equivalent to 6669, which plays an important role in improving the body stiffness.
3. Flexible Wrapping Technology The high quality of the body cover and the strict control of its precision make it difficult to put the traditional molding edging into large and poor flexibility. The roller hemming process of robots becomes an inevitable trend of edging flexibility. Mature automotive equipment suppliers in foreign countries already have many flexible aluminum alloy edging technologies, such as German ThyssenKrupp, American Hirotec, German Edag, and British DVA. At present, the suppliers of edge wrapping equipment for domestic aluminum alloy coverings are mainly European and American companies.
