Applied Welding Engineering: Processes, Codes, and Standards
While there are several books on market that are designed to serve a company's daily shop-floor needs. Their focus is mainly on the physically making specific types of welds on specific types of materials with specific welding processes. There is nearly zero focus on the design, maintenance and troubleshooting of the welding systems and equipment. Applied Welding Engineering: Processes, Codes and Standards is designed to provide a practical in-depth instruction for the selection of the materials incorporated in the joint, joint inspection, and the quality control for the final product. Welding Engineers will also find this book a valuable source for developing new welding processes or procedures for new materials as well as a guide for working closely with design engineers to develop efficient welding designs and fabrication procedures. Applied Welding Engineering: Processes, Codes and Standards is based on a practical approach. The book's four part treatment starts with a clear and rigorous exposition of the science of metallurgy including but not limited to: Alloys, Physical Metallurgy, Structure of Materials, Non-Ferrous Materials, Mechanical Properties and Testing of Metals and Heal Treatment of Steels. This is followed by self-contained sections concerning applications regarding Section 2: Welding Metallurgy & Welding Processes, Section 3: Nondestructive Testing, and Section 4: Codes and Standards. The author's objective is to keep engineers moored in the theory taught in the university and colleges while exploring the real world of practical welding engineering.

Corrosion of Weldments
Corrosion failures of industrial components are commonly associated with welding. The reasons are many and varied. For example, welding may reduce the resistance to corrosion and environmentally assisted cracking by altering composition and microstructure, modifying mechanical properties, introducing residual stress, and creating physical defects. This book details the many forms of weld corrosion and the methods used to minimize weld corrosion. Chapters on specific alloys groups--carbon and alloy steels, stainless steels, high-nickel alloys, and nonferrous alloys--describe both general welding characteristics and the metallurgical factors that influence corrosion behavior. Corrosion problems associated with dissimilar metal weldments are also examined. Case histories document corrosion problems unique to specific industries including oil and gas, chemical processing, pulp and paper, and electric power. Special challenges caused by high-temperature environments are discussed. Commonly used methods to monitor weld corrosion and test methods for evaluation of intergranular, pitting, crevice, stress-corrosion cracking, and other forms of corrosion are also reviewed.

Joining Processes: An Introduction
This is an introductory text for students of materials science and engineering interested in the scientific background to the joining and assembly of components in engineering systems. The principles of joining and the common methods employed to achieve a reliable joint are covered in chapters that all conclude with a summary of the points covered, and a set of problems for individual study, or class discussion. In the first chapters, thorough introductory overviews are given of firstly, the mechanical, chemical and physical phenomena related to surfaces, contacts and joins. In subsequent chapters, any necessary metallurgical or chemical background is adequately covered to enable students to understand the basic principles of a variety of joining methods, microelectronic devices and vacuum assemblies. Contents: Introduction; Surface Science; The Mechanics of Joining; Mechanical Bonding; Welding; Weld Metallurgy; Soldering and Brazing; Metal-ceramic Joints and Diffusion Bonding; Adhesives; Vacuum Seals; Micro-electronic Packaging.
Principles of Soldering
If you work with soldering processes or soldered components, Principles of Soldering will help you understand and solve practical engineering challenges. Clearly written and well referenced, this book takes you from the fundamental characteristics of solders, fluxes, and joining environments to the impact these have in the selection and successful use of soldering processes. Priority is given to the fundamental principles that underlie this field of technology rather than recipes for making joints. Striking a balance between being unduly simplistic or overly mathematical in their approach, the authors provide the critical analysis that is missing from much of the literature on soldering. An entire section is devoted to the difficult art of fluxless soldering and includes strategies for devising successful processes. The final chapter is devoted to recent advances in soldering technology and covers a variety of topics including lead-free solders, flip-chip interconnection, diffusion soldering, amalgams as solders, composite solders and other "hot" areas of research. Containing approximately 200 figures and 60 tables, this book updates and greatly expands the soldering content in the book Principles of Soldering and Brazing (1993) by the same authors. A companion volume, Principles of Brazing, is in development.
Solder Joint Reliability
The decision to move to lead-free solders has been made, but processing and performance challenges remain. This paper considers the transition in terms of performance, with particular emphasis on long term, high reliability applications. Comparison of key mechanical properties indicates generally beneficial outcomes of the transition to lead-free alloys, although there is a lack of understanding surroundingˆanomalous’’ observations, such as the effects of the bismuth. The lower melting point of Sn-Zn-Bi alloys, together with their comparable mechanical properties, provide further impetus to address their shortcomings during processing. Some lead-free alloys, such as Sn-0.5Cu, are susceptible to tin-pest formation following prolonged exposure below 138C, and this possibility remains for the more concentrated Sn-3.8Ag-0.7Cu alloy.

Welding Symbols on Drawings
Weld symbols on drawings was originally published in 1982 based on BS 499 (British Standards Institution 1980), ISO 2553 (International Standards Organisation 1979) and ANSI/AWS A2.4 (American Welding Society-1979) standards. These standards have been through numerous revisions over the last few years; and the current standards are ISO 2553 1992, BSEN 22553 1995, and ANSI/AWS A2.4 1998. The American system of symbolisation is currently used by approximately half of the world's industry. Most of the rest of the world use ISO. The British system was standardised in 1933 and the latest of five revisions was published in 1995 as BSEN 22553, which is identical to ISO 2553. For many years an ISO committee has been working on combining ISO and AWS to create a combined worldwide standard, but while discussions continue this could take many years to achieve. This contemporary book provides an up-to-date review on the application of ISO and AWS standards and a comparison between them. Many thousands of engineering drawings are currently in use, which have symbols and methods of representation from superseded standards. The current European and ISO standards and the American standard are substantially similar, but the ANSI/AWS standard includes some additional symbols and also symbols for non-destructive testing. Although symbols in the different standards are similar, the arrows showing locations of welds are different, these important differences are explained. ISO contains limited information on brazed or soldered joints these are covered in ANSI/AWS. Some examples of the application of welding symbols are also included.
