flapper peeningFlapper peening (also called "roto-peening") is a shot peening process that's ideal for peening in small and hard-to-reach areas. Flapper peening, first developed by 3M Corporation in the 1960s for U.S. Army helicopter field repair during the Vietnam war, is widely used in the aerospace industry today. Flapper Peening Training is available from Electronics Inc.
