Abstract: In 1991 the welding institute (TWI) invented abstract friction stir welding(FSW) method which is an innovative solid state material joining. In the last two decade this method is one of the most important joining technologies. In aerospace and automotive industries for their joining requirements these methods are using, which mainly focus on the joining of aluminum alloys. The joining of aluminum alloys by conventional welding processes can sometimes cause serious problems. Presence of segregation and porosities and including loss of alloying elements are the difficulties recognized during the solidification process and structure. The troubles existing during the solidification related with the convention fusion welding processes can overcome by the friction stir welding which offers an alternative through solid-state bonding.
