Friction stir welding (FSW) is a solid-state welding technique and is environmentally friendly. In this paper, the mechanical properties and corrosion resistance at the 45o rolling direction of the friction stir welded joints are investigated. The rotational speed, the traverse speed, and the tool pin plunge depth were kept constant at 500 rpm, 300 mm/min, and 5 mm respectively. The microstructure of the FSW joints showed the presence of pores in the welded zone. It is observed that the orientation angles of the welded plates affected the ultimate tensile strengths of the joints. The joints formed at 0° orientation exhibited the highest tensile strength of 289 MPa whereas that formed at 45o orientation was 282 MPa. The microhardness profile showed a marginal increase in the welded area (stir zone). The Open Circuit Potential (OCP) results of the welded area are lower than that of the base metal. The Electrochemical Impedance Spectroscopy (EIS) measurement of the base metal showed more resistance than the measurement carried out in the welded region. [ABSTRACT FROM AUTHOR] |
