Abstract: Friction Stir Welding is a solid state welding technique which can be used to produce sound welds between similar and dissimilar materials. Dissimilar welds which include welds between the different series of aluminium alloys, aluminium to magnesium, steel and titanium has been successfully produced by many researchers. This review covers the work conducted in the above mentioned materials and further concludes by showing the need to fully understand the FSW process in order to expand the latter industrially.
Abstract: Friction Stir Welding (FSW) is a solid state welding
process invented and patented by The Welding Institute (TWI) in the
United Kingdom in 1991 for butt and lap welding of metals and plastics. This paper highlights the benefits of friction stir welding
process as an energy efficient and a green technology process in the
field of welding. Compared to the other conventional welding processes, its benefits, typical applications and its use in joining
similar and dissimilar materials are also presented.
