The reality that aluminum alloys cannot be welded has been shattered
This is the magical creation of the National Pulse Strong Magnetic Field Science Center, a technological device built on the campus of Huazhong University of Science and Technology.
This is a strong magnetic field extreme experimental facility, which officially started construction in 2008, was completed in 2013, and officially passed national acceptance in October 2014. The acceptance experts believe that the facility has mastered the core technology. In 2019, it won the first prize of the National Science and Technology Progress Award.
International evaluation experts believe that the facility’s engineering achievements surpass those of similar countries, making it the best strong magnetic field facility in the world, and thus becoming a holy land for the international scientific community’s magnetic pursuers. After its completion, the facility provided 1894 scientific research services to over 130 domestic and foreign universities and research institutions. Researchers have achieved a large number of original results in this strong magnetic center.
Place a section of steel pipe and an aluminum pipe on top of the electromagnetic welding equipment here, and the two metal components of different materials will merge into one, which is as sturdy as the steel components welded by traditional welding techniques. The breakthrough in this technology undoubtedly greatly facilitates modern manufacturing and drives innovation in processing technology.
The manufacturing of large aluminum alloy components can save 90% of consumables, which will greatly reduce manufacturing costs, and this is electromagnetic forming technology.
The center has successfully developed the world’s first electromagnetic edge pressing, tooling, and forming integrated electromagnetic welding machine, achieving the overall forming and manufacturing of aluminum alloy shell parts for aerospace with a diameter of 1.38 meters. They will also complete the electromagnetic integral forming manufacturing of the bottom of the 3.35-meter rocket fuel storage tank.
