Joining of dissimilar materials by friction stir welding

Abstract

Welding is a process of joining materials into one piece. Welding is used extensively for pipe welding, aerospace, aviation, biomedical implants, fabrication of race cars, choppers, etc. Welding processes include thermal fusion joining processes and solid-state joining processes. Among solid-state joining processes, there is a friction stir welding which is applied to join two workpieces without materials. This technique of welding has great is used to weld dissimilar materials. This type of welding is gaining renewed interest, because the main objective is to reduce the total weight and maintaining essential physical properties. The objective of this paper is to focus on the friction stir welding of dissimilar materials.
