Abstract(s)
Friction stir welding is a relatively new joining technology, that has been succefuly applied
in the connection of large and complex structures, with considerable progress being made
throughout time. The development of this new solid-state welding technique has opened
up new possibilities for joining similar and dissimilar materials, allowing the obtention of
extremely interesting mechanical properties. This welding technique becomes even more
interesting when applied to materials that are traditionally considered difficult to weld by
conventional fusion methods. As it is well known, despite the fact that aluminum alloys
have a low melting point, these are difficult to weld due, mainly, to their high thermal
conductivity, requiring relatively high amounts of energy, wich can interfere with the low
melting temperature of the alloys. Thus, numerous studies have been carried out around
the Friction Stir Welding (FSW) process in various different alloys, however, given the
intensive use of aluminum alloys in the most diverse sectors, these have deserved special
attention by the researchers. In this chapter, the welding of different aluminum alloys with
different process parameters and their influence on mechanical property of the joints are
analyzed. This review intends to describe, in a structured way, the most recent
developments around FSW of aluminium alloys, with special attention given to the
microstructure and mechanical properties of the joints obtained by this process, as well as
the parameters able to achieve the best joint properties.
