Abstract

Friction Stir Welding (FSW) is one of the solid state welding methods where the welded joint is formed without the addition of filler metal. This study aims to determine the microstructure and mechanical properties of copper and copper joints (similar) with friction stir welding using variations in the shape of the pin, cylindrical, triangular and square. In this welding process using a milling machine with 900 rpm tool rotational speed parameters and a feed rate of 30 mm / minute. The material used in this study is copper with copper (similar) with a length of 150 mm, width 70 mm and thickness of 3 mm. The results of the average maximum stress value and the average maximum strain value on the variation of tapered cylinder tool pins are 191.16 MPa and 10.33%, on the square tool pin variations are 179.50 MPa and 13.85%, and the triangle tool pin variations are 153.42 MPa and 10.74 %. The average value of hardness in the weld area, HAZ, and base metal in the variation of tapered cylinder tool pins is 100.77 VHN, 85.16 VHN, 77.18 VHN, the variation of triangle tool pin is 101.88 VHN, 82.64 VHN, 64.77 VHN, and pin variation the square tool is 94.44 VHN, 80.23 VHN, 70.99 VHN. And for the results of the photo microstructure cross section of the triangle tool pin produces a micro structure that is smoother than the pin or tapered cylinder tool.
