Available in PDF, EPUB and Kindle. Book excerpt: The fundamental mechanisms of ultrasonic welding and the application of this process to the joining of various heat-resistant materials were investigated. Previous studies which had shown the effects of time, temperature, and clamping force on ultrasonic welds were expanded to include studies of the shear force during welding. Ultrasonic spot welds made in various combinations of heat-resistant alloys generally confirmed the results of previous work with these alloys. Cracks were found at the edges of the spot welds in most of the material combinations studied. The effects of these cracks on weldment properties varied with the material. The presence of a reaction zone, apparently consisting of intermetallic compounds, was apparent in ultrasonic welds made between Ti and stainless steel. These findings indicate that ultrasonic welding is not suitable for the production of aircraft-quality spot welds in heat- resistant and dissimilar metal combinations. It is apparent as a material's hardness increases, and the ratio of tensile strength to yield strength decreases, that weldability by the ultrasonic process decreases.

Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic Welding of Metal Sheets covers various aspects of ultrasonic welding (USW) of metal sheets, including the discussion on modeling and numerical simulations of ultrasonic welding to improve this welding process and performance. This book aims to provide an accessible, comprehensive and up-to-date exposition of the various aspects of joining of dissimilar metal sheets ranging from its fundamentals thorough to metallurgical characteristics covering fundamental concepts, in-detailed explanation about the USW including its implementation, design criteria, work material, welding, thermo-mechanical and research scopes. The book is aimed at researchers, professionals and graduate students in manufacturing, welding, mechanical engineering. Features The ultrasonic spot welding of various metal sheets is described in simplified expression and concepts are elucidated by relevant illustrations. Discusses modeling and numerical simulations of ultrasonic welding to improve the ultrasonic welding process and performance As opposed to competition in the market, this title provides thorough clarification of ultrasonic spot welding of metal sheets with its applications.

Download or read book A CRITICAL LOOK AT ULTRASONIC WELDING written by Thomas H. Hazlett and published by . This book was released on 1965 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical article reviews the state of the art of ultrasonic welding and discusses some of the advantages and disadvantages of the process. It examines several theories of the nature of the bond; factors affecting the strength of the bond; and the mechanisms and applications of the process. It concludes that although ultrasonic welding appears to be an attractive process, fundamental and applied research is necessary before it will find its special place in the field of joining similar and dissimilar metals.

Available in PDF, EPUB and Kindle. Book excerpt: The primary aim of this volume is to provide researchers and engineers from both academia and industry with up-to-date coverage of recent advances in the fields of robotic welding, intelligent systems and automation. It gathers selected papers from the 2018 International Conference on Robotic Welding, Intelligence and Automation (RWIA 2018), held Oct 20-22, 2018 in Guangzhou, China. The contributions reveal how intelligentized welding manufacturing (IWM) is becoming an inescapable trend, just as intelligentized robotic welding is becoming a key technology. The volume is divided into four main parts: Intelligent Techniques for Robotic Welding, Sensing in Arc Welding Processing, Modeling and Intelligent Control of Welding Processing, and Intelligent Control and its Applications in Engineering.

Download or read book Physical Principles of Ultrasonic Technology written by L. Rozenberg and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third work in a series of monographs* written by a col lective group of authors and is devoted to the physical mechanisms of specific ultrasonic technological processes that have already come into general use, as well as those which have just begun to enjoy practical applications. The problems covered in the book are exceedingly important insofar as the understanding of the phys ical mechanisms of ultrasonic processes forms the solitary basis of an intelligent approach to the design of industrial equipment and proper choice of optimum working conditions. The purely em pirical approach to the solution of these problems does not afford satisfactory results, because the state of affairs in a high-inten sity acoustic field is complex and diversified. Many papers in the Soviet Union and abroad have been con cerned with the practical utilization of ultrasound, but the over whelming majority is limited to the solution of highly individual ized practical problems, usually under conditions that are not amenable to comparison. Systematic studies have been initiated in the Ultrasonics Section of the Acoustics Institute of the Academy of Sciences of the USSR on the physics of high-intensity ultrasonic waves and their effects on matter; the results of these studies form the basis of the present book.
