    since fusion welding of dissimilar aluminium is tedious, friction stir welding ( fsw) process is widely used for welding of dissimilar materials, where the formation of secondary phase is absent since the temperature involved in this process is well below the melting temperature of base materials. welding is a fabrication process used to join materials, usually metals or thermoplastics, together.
