NASA gives Delphi grant to develop new welding process
I'm not sure why NASA is interested in this (they strike me as the type of folks who'd just bust out the TIG welder), but as far as autos are concerned, this low-cost way to join tubular members has some obvious applications for chassis, suspension components, subframes, and other structures. It's also notable in that it can join dissimilar materials, which would allow engineers to select the optimal material for each component.
