The opening chapter provides a comprehensive insight into dissimilar materials joined by FSW technology. FSW parameters such as tool design, tool pin offset, rotational speed, welding speed, tool tilt angle and position of workpiece material in the fixture for dissimilar materials are summarized. In the next chapter the author confirms the emission of particles in the nanorange during FSW of the most commonly used aluminium alloys, AA 5083 and AA 6082, which are originated from the aluminium alloy itself, due to friction of the welding tool against the workpiece. In the closing chapter, feasibility to join 2.5 mm thick AA5052 aluminium alloy and 1.4 mm thick high strength steel, DP590, by conventional FSW process (FSW) and TIG-assisted HFSW process (HFSW) is studied through couple experimental and numerical analysis. A comparative study in joining of dissimilar materials by conventional FSW and HFSW processes is performed to realize the effect of different welding parameters on the growth of IMC layer thickness.

Friction stir welding (FSW) is a highly important and recently developed joining technology that produces a solid phase bond. It uses a rotating tool to generate frictional heat that causes material of the components to be welded to soften without reaching the melting point and allows the tool to move along the weld line. Plasticized material is transferred from the leading edge to trailing edge of the tool probe, leaving a solid phase bond between the two parts. Friction stir welding: from basics to applications reviews the fundamentals of the process and how it is used in industrial applications. Part one discusses general issues with chapters on topics such as basic process overview, material deformation and joint formation in friction stir welding, inspection and quality control and friction stir welding equipment requirements and machinery descriptions as well as industrial applications of friction stir welding. A chapter giving an outlook on the future of friction stir welding is included in Part one. Part two reviews the variables in friction stir welding including residual stresses in friction stir welding, effects and defects of friction stir welds, modelling thermal properties in friction stir welding and metallurgy and weld performance.

Friction stir welding is a prominent solid-state joining process - which produces non-melting low heat input welds with less residual stresses compared to the conventional welding process. For almost 20 years, FSW has been used in high technology applications such as aerospace to automotive till high precision application such as micro welding. The main feature of a solid-state welding process is the non-melting of the work material which allows a lower temperature and a lower heat input welding process relative to the melting point of materials being joined. This is advantageous over the conventional fusion welding where excessive high heat input is required to melt the work material. It is thus considered to be the most significant development in the area of material joining over the past two decades. Friction stir processing (FSP) was later developed based on the basic principles of FSW. FSP has been proven to be an effective and versatile metal-working technique for modifying and fabricating metallic materials. FSW/FSP has prompted considerable scientific and technological interest since it has a potential for revolutionizing the manufacturing process in the aerospace, defense, marine, automotive, and railway industries. To promote widespread applications of FSW/FSP technology and ensure the structural integrity, safety and durability of the FSW/FSP components, it is essential to optimize the process parameters, and to evaluate thoroughly the microstructural changes and mechanical properties of the welded/processed samples. Advances in Friction-Stir Welding and Processing deals with the processes involved in different metals and polymers, including their microstructural and mechanical properties, wear and corrosion behavior, heat flow, and simulation. It summarizes recent advances in the microstructural evolution and mechanical properties of FSW/FSP alloys. Particular attention is paid to recrystallization mechanism, grain boundary characteristics, phase transformation, texture evolution, characteristic microstructures, and the effect of these factors on the hardness, tensile and fatigue properties as well as new approaches to the Friction Stir Welding.This book serves as a valuable guide to students, practitioners as well as researchers in manufacturing engineering, metallurgy and materials science, advanced materials, and welding technologies.

"Material flow and microstructure evolution are the two important aspects of the Friction stir welding (FSW) technique, which control the properties and performance of the friction stir welds. The present work investigates these two aspects of the FSW with main emphasis on the friction stir lap joints (FSLJs) on the AA6111 sheets. Due to the characteristic material flow during FSW, the faying surfaces in FSLPs are deposited in and around the weld nugget and create unavoidable defects. These defects reduce the load carrying thickness of the joints by providing an easy path for the weld failure. Therefore, to control the faying surface defects, a clear understanding of the material flow in FSW and its effect on the FSLJs is needed. With this objective, a comprehensive study of the material flow during FSLJs and the effects of various process parameters on the faying surface defects were conducted. This study not only revealed the mechanism of the formation of the faying surface defects but also explained the detailed material flow in the FSW. This investigation was further extended to study the role of FSW tool features on the material flow and the tool features to control the faying surface defects were proposed. The microstructure evolution during the FSW of AA6111 was investigated by differential scanning calorimetry (DSC), microhardness and transmission electron microscopy (TEM) techniques. This study showed that the increase in the heat input during FSW resulted in better aging response of the joints. The microhardness and strength variation across the FSW weld were explained from the DSC and TEM observations"--Abstract, leaf iv.

In friction stir welding (FSW) of two similar or dissimilar metals, the work materials are positioned in such a way against a rotating-travelling stirring tool that allow FSW operations to be performed. The operation is begun by pushing the bottom of rotating tool pin against the initial position of weldment to be produced along desired welding line. The push by the bottom of rotating tool pin on the surface of work materials to be welded is made in order to generate local heating by mechanical friction. This book examines the weldment formation in friction stir welding.
