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.

Assessment of Adhesively Bonded Joints of Similar and Dissimilar Materials: Industrial Case Study

“…Due to these advantages, joining polymer and metal parts, especially in the automotive and aviation industries, is of interest [1,2]. There are several joining methods, such as mechanical fastening and adhesive bonding, that can be used to achieve successful metal/polymer bonding [3][4][5]. The chemical and physical properties of the materials to be joined [6], as well as the processing durations, health effects, cost, and bond strengths of the joining processes are very different from each other [7].…”

Influence of Tool and Welding Parameters on the Risk of Wormhole Defect in Aluminum Magnesium Alloy Welded by Bobbin Tool FSW

“…The tool has two functions: (1) heating the material and (2) containing and directing the softened/plasticized base material of the weld [10]. Being a solid-state welding process, FSW enables the welding of dissimilar materials, e.g., different alloys with the same base metal, such as AA5052 to AA6061 [11], and dissimilar materials such as aluminum with copper, magnesium, or steel [13][14][15][16][17]. FSW, since it was patented, has shown great potential in further development of process variants, from the point of view of welding of different materials, base material thicknesses, and other specific aims, such as technological advantages.…”
