A 'first' in space travel was achieved for friction stir welding as the last millennium drew to a close.

The award winning process was invented by TWI in the nineties and used last year for sealing liquid oxygen propellant tanks on the Boeing Delta II space rocket.

The vehicle took to the skies from Cape Canaveral on 17 August 1999 carrying four telecommunications satellites for Globalstar.

Apart from TWI's continuing developments in friction stir welding of aluminium alloys for Boeing and other Industrial Members, work has continued to develop the process for steel, titanium, copper, lead and magnesium.
