ABSTRACT
Joining of dissimilar metals plays a predominant role in modern manufacturing industry. Friction welding is a kind of solid-state metal joining process, which is used to fuse the similar or dissimilar metal alloys with the help of various parameters such as frictional force, friction time, friction speed, forge pressure, and forge time. Rotary friction welding (RFW) is a simple form of friction welding process. Continuous friction welding and inertia friction welding are two variants of RFW. This chapter reviews friction welding between ferrous metal alloys and between nonferrous metal alloys. Sundara Bharathi et al. investigated on AA2024 and AA6061 similar and dissimilar friction-welded joint. They noted that yield and ultimate tensile strength of the joint is poorer than base metal alloy and found variations in hardness measurement on both similar and dissimilar joints. The chapter discusses finite element model in friction welding.
