This comprehensive text maximizes reader's understanding of all aspects of welding, brazing, and soldering, explaining traditional as well as advanced joining technologies, including welding metallurgy, safety, testing, quality assurance (QA), and automation/robotic welding. The book contains 200 worked numerical examples, 120 diagrams/illustrations, and 100 multiple-choice questions (MCQs) with their answers. It covers the theory of welding with respect to the physics of welding and metallurgy and the residual stresses and distortions with detailed mathematical analyses and calculations. A range of welding practices are discussed, covering welding design, testing of weldments, fusion welding processes (OFW, SMAW, GMAW, GTAW, SAW, FCAW, PAW, ESW, RSW, RSeW, FEW, and LBW), solid-state welding processes (cold-pressure welding, USW, EXW, DBW, FW, RW, and other.),  advanced welding processes (MPW, magnetic pulse welding, FSW, EBW, etc.). The book contains several case studies on failures of weld joints in structures/machine components. The volume prepares undergraduate students in mechanical, metallurgical, and manufacturing engineering for success in courses in welding and joining technology. In addition, graduate students, researchers, and practitioners would benefit from this book because it stands as a ready reference for both fundamentals and advances in welding and joining technologies.
