Dana Applies Magnetic-Pulse Welding To Hydroformed Frame To Reduce Weight, Increase Design Flexibility
Oct 20, 1999
TOLEDO, Ohio, Oct. 20 /PRNewswire/ -- After recently unveiling magnetic- pulse welding as a new process for joining steel and aluminum on driveshafts, and winning the Automotive Manufacturing Award at the Frankfurt International Motorshow, Dana Corporation (NYSE: DCN) is using the same technology to take frames and other structural products to the next level. Magnetic-pulse welding is a process that joins ferrous and non-ferrous materials, such as steel and aluminum. Through this proprietary, electronic process, Dana can produce a smooth-weld bond that, which outperforms conventional welding, with no heat. Combining magnetic-pulse welding with new advancements in high-pressure hydroforming of steel and aluminum is enabling the company to develop innovative designs, while continuing to reduce the weight of its structures. Using this technology for structures following its introduction in driveshafts is consistent with Dana's strategy of sharing "enabling technologies" among product groups. Dana's Structural Products Group is now using magnetic-pulse welding along with its innovative hydroforming processes to enhance its structural technology. In fact, Dana can hydroform unique aluminum crossmembers, thus reducing manufacturing costs and use magnetic-pulse welding to join the cradles to steel siderails, all with a new level of precision. The result is more design flexibility, with less weight. "These technological developments significantly reduce the cost and mass of current technologies and give our customers a tremendous advantage in the development of products such as space frames," said Mike Greene, vice president of structural products. Dana Automotive Systems Group provides under-the-vehicle products, integrated modules and systems to customers anywhere in the world. Automotive Systems Group consists of Spicer(R) axle products, Spicer(R) driveshaft products, Parish(R) structural products, Nakata(R) steering and suspension, FTE(R) brake and clutch systems, and a systems engineering integration and logistics unit. Dana Corporation is one of the world's largest independent suppliers to vehicle manufacturers and the aftermarket. Founded in 1904 and based in Toledo, Ohio, the company operates some 330 major facilities in 32 countries and employs more than 86,000 people. The company reported sales of $12.5 billion in 1998.
