2 nd International Symposium on Friction Stir Welding

Gothenburg, Sweden, 27-29 June 2000

The 2 nd Friction Stir Welding Symposium in Gothenburg, Sweden revealed the speed with which industrial companies are now applying FSW technology, invented and patented by TWI in the UK in 1991, to a great range of products. 155 delegates from 16 countries including Australia, Japan and the USA, as well as nearer to home, listened to 35 papers.

The Proceedings are available on a CD-ROM.
