However well equipped the workshop may be there seems to be an incessant need to make up special gadgets of one sort or another. These may range from mutilating a clothes peg to act as a 'third hand' up to major modifications to an existing machine tool. The making of such devices can be fun (indeed, some may appear to do nothing else!) but nevertheless the time taken up in 'devising the device' can often delay the completion of an important project. Shared experience is a most potent tool in reducing such delays, and can, moreover, often provide solutions to problems hitherto believed to be intractable. Tubal Cain has enjoyed more than sixty years' experience in designing and building engines and machines (in both full size and model dimensions) and over this time has made many ancillary devices. In this book he shares 52 of them with you. A number of these had been published in magazines from time to time and some were assembled in volume form about thirty years ago. The opportunity was later taken not only to reprint that book but to revise some of the entries to take advantage of user experience, to add new material and to introduce it into the popular Workshop Practice Series.

Describes the weldability aspects of structural materials used in a wide variety of engineering structures, including steels, stainless steels, Ni-base alloys, and Al-base alloys Welding Metallurgy and Weldability describes weld failure mechanisms associated with either fabrication or service, and failure mechanisms related to microstructure of the weldment. Weldability issues are divided into fabrication and service related failures; early chapters address hot cracking, warm (solid-state) cracking, and cold cracking that occur during initial fabrication, or repair. Guidance on failure analysis is also provided, along with examples of SEM fractography that will aid in determining failure mechanisms. Welding Metallurgy and Weldability examines a number of weldability testing techniques that can be used to quantify susceptibility to various forms of weld cracking. * Describes the mechanisms of weldability along with methods to improve weldability * Includes an introduction to weldability testing and techniques, including strain-to-fracture and Varestraint tests * Chapters are illustrated with practical examples based on 30 plus years of experience in the field Illustrating the weldability aspects of structural materials used in a wide variety of engineering structures, Welding Metallurgy and Weldability provides engineers and students with the information needed to understand the basic concepts of welding metallurgy and to interpret the failures in welded components.

The book is aimed at those wishing to gain a basic knowledge of the practical aspects of the four most widely used welding processes: manual metal arc (MMA), metal inert/active gas (MIG/AG), tungsten inert gas (TIG) and oxy-acetylene welding and cutting. In addition to a detailed treatment of these four methods, further sections deal with the various angles at which welding can be carried out, the effect of the different materials, and quality assessment. Important safety information is collected into a preliminary section whilst highlighted safety warnings carry the safety theme through the entire text. Features to aid comprehension include a glossary of welding terms and symbols, self-assessment questions and a guide to current welder qualifications in the light of recent European standardisation.

This is the second volume of three designed to give an insight into the current state of CNC technology with a focus on practical applications. Following a brief historical introduction to cutting tool development, chapters 1 and 2 explain why CNC requires a change in cutting tool technology from conventional methods. A presentation is given of the working knowledge of cutting tools and cutt ing fluids which is needed to make optimal use of the productive capacity of CNC machines. Since an important consideration for any machine tool is how one can locate and restrain the workpiece in the correct orientation and with the minimum of set-u p time, chapter 3 is concerned with workholding technology. The author draws on his extensive experience as a practitioner and teacher. The text is thoroughly practical in character and generously illustrated with diagrams and photographs.

The first part of Volume I outlines the origins and development of CNC machine tools. It explains the construction of the equipment and also discusses the various elements necessary to ensure high quality of production. The second part considers how a company justifies the purchase of either cells or systems and illustrates why simulation exercises are essential prior to a full implementation. Communication protocols as well as networking topologies are examined. Finally, the important high-speed machining developments and the drive towards ultra-high precision are mentioned. Following a brief historical introduction to cutting tool development, chapters 1 and 2 of Volume II explain why CNC requires a change in cutting tool technology from conventional methods. A presentation is given of the working knowledge of cutting tools and cutting fluids which is needed to make optimal use of the productive capacity of CNC machines. Since an important consideration for any machine tool is how one can locate and restrain the workpiece in the correct orientation and with the minimum of set-up time, chapter 3 is concerned with workholding technology. Volume III deals with CNC programming. It has been written in conjunction with a major European supplier of controllers in order to give the reader a more consistent and in-depth understanding of the logic used to program such machines. It explains how why and where to program specific features of a part and how to build them up into complete programs. Thus, the reader will learn about the main aspects of the logical structure and compilation of a program. Finally, there is a brief review of so me of the typical controllers currently available from both universal and proprietary builders.

The Science and Practice of Welding, now in its tenth edition and published in two volumes, is an introduction to the theory and practice of welding processes and their applications. Volume 2, The Practice of Welding, is a comprehensive survey of the welding methods in use today and gives up-to-date information on all types of welding methods and tools. Processes described include manual metal arc welding (MMA or SMAW); gas shielded metal arc welding (MIG, MAG or GMAW); tungsten inert gas shielded welding (TIG or GTAW) and plasma arc (PA) and cutting. Resistance, flash butt and oxy-acetylene welding are also included. Cutting processes are given a separate chapter. This new edition has been brought right up-to-date with a new chapter on the welding of plastics, and new sections on the welding of duplex stainless steel and air plasma cutting. The text is illustrated by up-to-date photographs of plant and equipment. As in previous editions, the appendices bring together a wealth of essential information, including British and American welding symbols, tables of conversion, information on proprietary welding gases and mixtures, testing practices, safety features and tables of brazing alloys and fluxes. Both volumes contain numerous questions of the type set at craftsman and technician grade of the City and Guilds of London Institute examinations.

The Study Guide helps reinforce your understanding of concepts presented in the text. Each chapter starts with a review of the important topics discussed in the chapter. You can then test your knowledge by answering additional questions and completing lab exercises (as appropriate) to reinforce the primary objectives of the lesson, and view artwork and safety precautions.

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.
