Abstract—Friction stir welding, a solid state joining technique, is widely being used for joining Al aloys for aerospace, marine automotive and many other aplications of commercial importance. FSW trials were caried out using a driling machine on Al 6063 aloy. The tol rotational speds 485, 710, 910, 120 and 140 rpm with a traverse sped 4 mm/min were aplied. The Mechanical properties of welded joints were investigated using diferent mechanical tests including destructive test (tensile test, hardnes and microstructure). Based on the stir welding experiments conducted in this The resultant microstructure was characterized using optical microscopy This paper presents the optimization of friction stir welding for pipe and also highlights the influence of microstructure and mechanical properties of FSW 6063 Al aloy.
