Popis: Friction stir welding FSW as a solid state joining process is being known recently by many industries due to its capability to reduce defects energy efficient and environment friendly compared with conventional techniques Specifically FSW can be used to join high ndash strength aluminum alloys like XXX and XXX which are hard to weld by conventional fusion welding In this review paper the elementary principles of FSW parameters and the effect of the FSW parameters on microstructure and mechanical properties are addressed Although this process has a lot of advantages compared with fusion techniques however many problems still remain unsolved related to poor mechanical properties of weldment s heat affected zone HAZ In this regard the impact of post weld heat treatment PWHT on improvement of joint properties is addressed Finally appropriate parameters and factors for achieving the best condition of the weld is discussed
