Abstract

Friction Stir Welding (FSW) is a welding process utilizing heat due to rotation of the tool that rubs against the chief metal under large axial pressure in the welding area. This friction stir welding method is generally used to connect aluminum material. The purpose of this thesis research is to determine the effect of tool rotation speed with variations in single side and double side connections to the mechanical properties and microstructure of similar metal joints. The friction stir welding process uses a milling machine for material AA 2014 with a length of 100 mm 50 mm wide and 3 mm thick. The parameters used are feed rate 10 mm / minute and the slope angle of the tool 3o with variations in tool rotation speed 1500 rpm and 915 rpm and variations in the type of continuous single side butt joint and double side butt joint. Test specimens of welding results include, tensile test, micro vickers hardness test, and microstructure test. The results show that the variation of tool rotation speed of 915 rpm and double side junction type have the highest tensile stress of 332.14 MPa. In the hardness testing of micro vickers the nugget weld area has a high hardness value compare to the chief metal and HAZ, this occurs in all variations. The microstructure of the HAZ region has grain growth due to the temperature received, while the weld nugget shows a small microstructure and tight appearance.
