Extensively revised and updated from the eighth edition, this comprehensive volume enlisted more than 50 experts in materials and materials applications assure its accuracy and the currency of its content. It is a great reference source for engineers, educators, welding supervisors, and welders.  The handbook covers carbon and low-alloy steels: high-alloy steels: coated steels; tool and die steels; stainless and heat-resisting steels; clad and dissimilar metals; surfacing cast irons; maintenance and repair welding; and underwater welding and cutting.
Scope : This is Volume 4 of the five-volume series in the Ninth Edition of the Welding Handbook. It is Materials and Applications, Part 1, presented in ten peer-reviewed chapters covering the metallurgical properties of various forms of ferrous metals and how these properties affect welding. The titles of the chapters in this book, which includes two applications chapters, indicate the variety of challenges presented to welders, designers, welding engineers, and others in the welding workplace. The ability of scientists to examine the microstructures of the metals, identify constituent elements, and determine how the properties of the metals can be used and controlled during welding is reflected in the updated and expanded information in this book. Many of the best scientists in the welding industry from university, government or other research laboratories, metals producing companies, fabricators, consulting firms, and testing facilities have stepped forward as volunteers to update this volume. These highly regarded experts are recognized on the title pages of their respective chapters. Three basic chapters of this volume, Chapter 1, Carbon and Low-Alloy Steels; Chapter 2, High-Alloy Steels; and Chapter 5, Stainless and Heat-Resistant Steels contain detailed sections on the metallurgy, composition and properties of steels, and methods of producing high-integrity welds in carbon steels, alloy steels, and stainless steels. Different sets of welding conditions, challenges, and solutions are presented for the specialized steels represented in Chapter 3, Coated Steels; Chapter 4, Tool and Die Steels; Chapter 6, Clad and Dissimilar Metals; Chapter 7, Surfacing Materials; and Chapter 8, Cast Irons. The chapters provide information on the composition, metallurgy, weldability, and recommended welding procedures for these metals. Two major applications are included in this volume. Chapter 9, Maintenance and Repair Welding, contains a model for a systematic approach to the sometimes difficult procedures involved in repair welding. Chapter 10, Underwater Welding and Cutting, contains critical information on producing strong, durable welds, sometimes under very difficult welding conditions, for use in the severest of service conditions. A table of contents of each chapter is outlined on the cover page, along with names and affiliations of contributors of the updated information. A subject index with cross-references appears at the end of the volume. Appendix A contains a list of safety standards and publishers. Frequent references are made to the chapters of Ninth Edition Volumes 1, 2, and 3. To avoid repetition of information published in these volumes, a reference guide is presented in Appendix B. This book follows three previously published volumes of the Ninth Edition of the Welding Handbook: Volume 1, Welding Science and Technology, which provides prerequisite information for welding and the welding processes; Volume 2, Welding Processes, Part 1, which contains the technical details of arc welding and cutting, the gas processes, brazing, and soldering; and Volume 3, Welding Processes, Part 2, which is devoted to the resistance, solid state, and other welding processes, such as laser beam, electron beam, and ultrasonic welding.
