What is friction stir welding of aluminum?

Q - I have heard of a welding process called Friction Stir Welding. Apparently, it is quite new and it is a particularly good process for welding aluminum. Can you give me some information on this process and the types of appliions for which it is used? A - Invented in 1991, the friction stir welding (FSW) process was developed at, and is patented by, The Welding Institute (TWI) in
