Friction Stir Welding (FSW) is a relatively novel joining technique which was invented by The Welding Institute (TWI), UK in 1991 [1]. Major advantage of this method is of being a solid state welding technique i.e. unlike in conventional welding procedures, no melting is involved during this process. Moreover no filler material and special edge preparation requirements give this method an environmental and economic edge over other methods of welding [2, 3].

In this presentation following main agendas shall discussed:

1.    An overview of the FSW process

2.    Extent of its application domain and

3.    Review of feasibility studies
