Drawing on state-of-the-art research results, Resistance Welding: Fundamentals and Applications, Second Edition systematically presents fundamental aspects of important processes in resistance welding and discusses their implications on real-world welding applications. This updated edition describes progress made in resistance welding research and practice since the publication of the first edition. New to the Second Edition: Significant addition of the metallurgical aspects of materials involved in resistance welding, such as steels, aluminum and magnesium alloys, zinc, and copper Electric current waveforms commonly used in resistance welding, including single-phase AC, single-phase DC, three-phase DC, and MFDC Magnesium welding in terms of cracking and expulsion The effect of individual welding parameters 2-D and 3-D lobe diagrams New materials for the ultrasonic evaluation of welds, including A-scan, B-scan, and in-line A-scan The book begins with chapters on the metallurgical processes in resistance spot welding, the basics of welding schedule selection, and cracking in the nugget and heat-affected zone of alloys. The next several chapters discuss commonly conducted mechanical tests, the monitoring and control of a welding process, and the destructive and nondestructive evaluation of weld quality. The authors then analyze the mechanisms of expulsion-a process largely responsible for defect formation and other unwanted features-and explore an often overlooked topic in resistance welding-related research: the influence of mechanical aspects of welding machines. The final chapters explain how to numerically simulate a resistance welding process and apply statistical design and analysis approaches to welding research. To obtain a broad understanding of this area, readers previously had to scour large quantities of research on resistance welding and essential related subjects, such as statistical analysis. This book collects the necessary information in one source for students, researchers, and practitioners in the sheet metal industry. It thoroughly reviews state-of-the-art results in resistance welding research and gives you a solid foundation for solving practical problems in a scientific and systematic manner.

This textbook covers chemical thermodynamics in materials science from basic to advanced level, especially for iron and steel making processes. To improve a process by applying knowledge of thermodynamics or to assess the calculation results of thermodynamic software, an accurate and systematic understanding of thermodynamics is required. For that purpose, books from which one can learn thermodynamics from the basic to the advanced level are needed, but such books are rarely published. This book bridges the gap between the basics, which are treated in general thermodynamic books, and their application, which are only partially dealt with in most specialized books on a specific field. This textbook can be used to teach the basics of chemical thermodynamics and its applications to beginners. The basic part of the book is written to help learners acquire robust applied skills in an easy-to-understand manner, with in-depth explanations and schematic diagrams included. The same book can be used by advanced learners as well. Those higher-level readers such as post-graduate students and researchers may refer to the basic part of the book to get down to the basic concepts of chemical thermodynamics or to confirm the basic concepts. Abundant pages are also devoted to applications designed to present more advanced applied skills grounded in a deep understanding of the basics. The book contains some 50 examples and their solutions so that readers can learn through self-study.

What makes this book unique is a specific focus on aluminum recovery, rather than just recycling in general. It also offers an integrated discussion of scrap recovery and re-melting operations and includes economic as well as technical elements of recycling.

This second edition features more information on aluminum scrap pricing and the economics of recycling, the analysis of dross processing methods currently in use by the industry, and drosses produced. The book has been updated throughout to include the most up-to-date information.

A commonly used practice in industry is the machining of sculptured part surfaces on a multiaxis numerical control (NC) machine. While this practice is vital, it is also a costly aspect of the surface generation process. After investing more than 40 years of research into the theory of part surface generation, the author of Generation of Surfaces: Kinematic Geometry of Surface Machining considers an approach that provides optimal machining while factoring in the lowest possible cost. This book presents the modern theory of part surface generation with a focus on kinematic geometry of part surface machining on a multiaxis (NC) machine, and introduces key methods for applying the DG/K-based approach to part surface generation. The DG/K approach is based on the results of research found in two main areas: differential geometry (DG) of surfaces, and kinematics (K) of rigid body in three-dimensional Euclidian space E3. It is an extremely powerful tool for solving a plurality of problems in mechanical/manufacturing engineering. The text is presented in three parts: the basics, the fundamentals, and applications of part surface generation. The first part of the book provides an analytical description of part surfaces, details the principal elements of the theory of multiparametric motion of a rigid body in E3 space, and defines applied coordinate systems. The second half introduces the theory of part surface generation, and includes an analytical description of contact geometry, while the final portion illustrates the potential development of highly effective part surface generation methods. The author illustrates the most complex features of the book with examples, explains all of the results of analysis mathematically, and uses just one set of input parameters-the design parameters of the part surface to be machined. The book considers practical applications for part surface machining and cutting tool design. Developed for use with computer-aided design (CAD) and computer-aided machining (CAM), this text is useful for anyone starting work on new software packages for sculptured part surface machining on a multiaxis NC machine.

Pipeline integrity is key to maintaining operational success, safety and security and minimising harm to the environment. Corrosion is a dominant contributory factor to failures, leaks and integrity threat in pipelines. Therefore, its optimum control within an integrity management framework is paramount for the cost effective design of facilities and ensuring continued, uninterrupted and safe operations within the expected design life. This recommended practice (RP) is a compendium of current best practices and state of the art knowledge by major operators, engineering contractors and service companies involved in hydrocarbon production and transportation. The RP incorporates some minimum operational requirements and practices to ensure that when managing corrosion in pipelines, fundamental principles are followed. It covers management of corrosion for pipelines carrying hydrocarbons, injection water and/or produced water from design to decommissioning. It is structured to follow the logical steps of a basic corrosion management process and makes references to relevant and available International standards and/or recommended practices. It is intended for use by personnel from the petroleum industry having knowledge of corrosion and materials. It is hoped that this RP will prove to be a key reference document for engineers, suppliers and contractors working in the oil and gas industry, paving the way for corrosion free operation of pipelines with the ultimate goal of improving safety, security and minimising the impact on the environment.

The world's output of metals during the 100 year period of 1863-1963 was greater than in all the previous years of man's history. In the nineteenth century the only metals available to industry were cast and wrought iron and a few non-ferrous metals and their alloys; by the latter part of the twentieth century, steel and aluminum dominated the world, and metals that were mere laboratory curiosities provided the basis for the technology of nuclear energy and space travel. This book records the extraordinary history of metallurgical progress, in which metal art was replaced by metal science. It remains a classic work on the subject. The book begins with an introductory chapter that surveys the entire field to be covered, and follows with eight chapters each dealing with progress in one of the major branches of the metallurgical industry: ore dressing, pyrometallurgy, iron and steel, the major non-ferrous metals, new metals (such as uranium, germanium and cobalt), precious metals, the shaping of metals, and metallography. The book reviews developments in all countries, but American practice - which led the world - is given special prominence. A glossary of metallurgical terms and full name and subject indexes are included. The book is a basic reference work as well as an absorbing history of an important aspect of man's technological progress.
