Abstract

This  article  reports  the  results  of  applying  the  response  surface  methodology  to  evaluate  the  tensile  strength  in  joints obtained by the process of friction-stir welding (SFA), depending on the speed of rotation of the tool and welding speed. The joints were welded with a conventional milling machine capable DECKEL FP4M 3 HP and a threaded cylindrical pin. In  the  microscopic  images  clearly  shows  the  effect  of  the  dynamic  recrystallization  in  the  stirred  zone  (ZA). Microhardness profiles show the typical shape of W and with metallography performed on samples tested at tension that Heat  Affected  Zone  (HAZ)  is  the  weakest microstructural areas of  the  join.  The  greater  tensile  strength  of  the  welded joints  of  the  aluminum  alloy  AA  6261-T5  by  SFA  (191.63  MPa)  was  obtained  using  the  threaded  cylindrical  pin,  a welding speed 315 mm / min and a rotation speed of 1600 rpm.
