Influence of Flywheel for Drive System of Rotary Friction Welding and Chamfer Angle Variations Forging to Welding Strength
The purpose of this paper is to study a flywheel addition on rotary friction welding drive system, which to analyzing between chamfers angle variations and tensile strength. The flywheel addition performed as energy storage that was functioned to stores energy when supply exceeds demand and release it when supply was smaller than need. In this paper was conducted an experimental study to analyze the influence of flywheel addition mass to drive system of rotary friction welding. The test specimens were given chamfer variations and the forging surface was constant at 4 mm with variations of chamfer angle of 30ᴼ, 45ᴼ, and 60ᴼ. From the tests were carried out mass of flywheel and chamfer angle that affected on process and results of welding. The results of the test were obtained highest value of tensile strength at specimens that used flywheel 3 with a chamfer angle of 45ᴼ, which has a value of 554.1 Mpa.
