Abstract

Friction Stir Welding (FSW) is a welding technology where the process is a solid connection that can be used to connect materials that are difficult to weld on fushion welding. This research is using friction stir welding method to find out the effect variation of feedrate on mechanical characteristic and micro structure on dissimilar metals joint between Fe and AA 1100 with 3mm thickness, The welding process is using a milling machine with variation of feedrate parameters are 25 mm / min, 30 mm / min, and 40 mm / min. The constant parameters that used are the speed of rotation tool 1500 rpm and the tilt angle tool of 30. Then the tests include tensile test, macro hardness test, and micro structure test, The results showed that the feedrate 30 mm / min had the highest tensile strength of 41,17 MPa. This was influenced by the temperature produced by feedrate. In the weld nugget region the hardness value is influenced by the Intermetallic compound FexAly and for the highest hardness value in the weld nugget of 126.829 HVN. The micro structure in the HAZ area is grain growth due to the received temperature, while on the weld nugget shows a small and tight micro structure look.
