ASM Handbook, Volume 6A: Welding Fundamentals and Processes is a focused revision of the welding process information in the 1993 Volume 6: Welding, Brazing, and Soldering. The new volume expands on the fundamental principles of welding, including heat transfer, solidification, residual stress and distortion, and has an all-new section on modeling and simulation of welding processes. Articles cover all welding processes, from the workhorse methods of arc and resistance welding, to newer methods like friction stir welding and laser beam welding, to specialty methods like explosive welding and ultrasonic welding. One-third of the articles are all-new, and welding articles from the 1993 edition have been updated and expanded, making this volume the most complete reference source anywhere on welding fundamentals and processes. From theory to practice, the book is a comprehensive resource for evaluating and selecting welding methods, working with vendors, understanding how processing variables affect welding outcomes, and more.
