Abstract
Friction stir welding (FSW) is solid state joining technique or the metal didn't melt when joining process. This method is used the characteristic of the parent metal has not change. This process is widely used for materials, especially aluminum heat treatment usually must be done first before welding, FSW method invented by The Welding Institute W. Thomas from the welding institute (TWI). Friction stir welding process is used to alumunium 5052 T-0 to form butt joint as much as nine plate. Parameter which varied is pin design form with form triangle, cylinder and cone with screw. The next testing which includes the observation radiography test, tensile test, hardnest test and metallography examination. The results of the study that the variation of the form triangle screw, cylinder screw and cone screw cause hardness value and tensile strength increase and a decrease to triangle screw. Of variation this thesis hardness and tensile strength was highest in cylinder screw as big as 38.27 HV and 120.442 MPa
