A Study on FSW Parameters of Joining Dissimilar Metals - Al and Fe

Abstract

The materials with similar and dissimilar qualities are joined effectively in their solid-state by Friction Stir Welding (FSW). FSW eliminates the conventional problems and produces crack-free and completely solidified joints. In recent years the commercialization of FSW is focused on metals like Fe and Al-based alloys. However, to commercializesuch a process numerous research studies are required to characterize and establish process windows. FSW process is suitable for joining the different materials having different mechanical and chemical properties and for different material structures. In general, aerospace applications require hybrid metal joins to offer high strengthhigh ductile properties by joining varied metal alloys. FSW is the feasible way to join such metals to get high properties. This review mainly provides the feasibility ofthe FSW technique to join the different materials/alloys.
