Varied Corner Joint Design Alumunium 6061 uing Friction Stir Welding

The object of this research was aluminum 6061 with 150 mm length, 50 mm wide, and 10 mm thick. The probe utilized is one of with simple design was made from hardened EMS 45. The observed aspect was microstructure in a specific temperature that would affect of the strength the material. Apart from the microstructure, the observation also covered the macrostructure and the temperature. The analysis of the result also involved several tests including hardness test, x-ray, and tensile test. The determined parameter for this research was the feed rate speed that ranged from 6 mm/min, 8 mm/min, 10 mm/min, 15 mm/min, and 30 mm/min and varied corner joint (Corner-Butt 45, Corner-Butt, and Corner-Lap 45). The rotation speed varied set at 1000 rpm, 1500 rpm, and 2000 rpm. The heat generated, the acquisition data was then calculated. The experiment is highest value of tensile test was 163 MPa, acquired from Corner-Butt joint 45 with 10 mm/min feed rate speed. It was verified by the heat temperature that ranged from 300-420o C and clarified by its micro and macrostructure..
