Friction Stir Welding transforms the metals from a solid state into a "plastic-like" state, and then Lockheed Martin, Reynolds Aluminum and the labs at Marshall Space Flight Center in Huntsville A significant benefit of Friction Stir Welding is that it has significantly fewer process elements to control. Friction stir welding is a recent modification on friction welding. It is suited to aluminium, magnesium and other metals and can join dissimilar materials. Advantages over fusion welding are, no porosity, fumes or arc and little chance of distortion. Main applications are in the automotive industry. • The welds of RFSSW consist of four microstructural regions: • Stir Zone (SZ): experiences intense plastic deformation and frictional heating during the joining • Produce a comparative study of control AA 6061 refill friction stir spot welded to AA 2024 to AA 6061 and AA 7075 to AA 6061 welds. Keywords: Friction stir welding, Friction stir processing, Tool, Shoulder, Probe. This paper is part of a special issue on Advances in High Temperature Joining of Materials. National Research Council Canada, Institute of Aerospace Research, Aerospace Manufacturing Technology Center The applicability of friction stir welding types and its application in rail joining was investigated. A number of machine concepts for joining rail using friction stir welding techniques were developed and a final workable concept was laid out. Friction stir welding (FSW) is a method for joining metal or metal alloy parts at a joint by using heat friction generated from a spinning tool to weld the different section. Because the metal is not melted during FSW, it is referred to as a solid-state joining process. A relatively new technique, FSW was MTI's Friction Stir Welding process development and part production is making a dramatic impact across many industries, including aerospace, defense Superior mechanical characteristics Friction Stir Welding produces a weld with high weld strength and toughness, plus a fine grain structure that Friction stir welding is a promising solid-state welding technique. The LAB fraction is only 27.5%. This means that the weld microstructure was fully recrystallized during the welding process. Advances in friction stir spot welding. Critical Reviews in Solid State and Materials Sciences, 2019 Friction stir welding uses the high rotational speed of a tool and the resulting frictional heat created from contact to crush, stir together, and forge a bond between two metal alloys. A welding tool moves along the area to be joined while rotating at a high speed. The action between the tool and the Friction stir welding was invented at The Welding Institute (TWI) in the UK in 1991. This relatively new, solid-state joining process differentiates itself from many other welding processes by not melting the workpiece. As a result, the joining process generates excellent joint properties, is energy efficient 1. INTRODUCTION. 1.1. Friction Stir Welding Process Friction stir welding (FSW) is a novel solid state joining process patented in 1991 by The Welding Institute, Cambridge, UK [1]. One of the main advantages of FSW over the conventional fusion joining techniques is that no melting occurs. Par Systems' friction stir welding systems are driven by innovative I-STIR technology.

In this work, the current state of understanding of grain structure evolution during friction-stir welding is briefly reviewed. The broad aspects of this process and experimental techniques for its examination are critically addressed.
