Synthesis Lectures on Welding Engineering – serie

The book begins with thorough coverage of Resistance Spot Welding fundamentals and principles, including concepts such as Lobe Curves, contact resistance vs. electrode force, dynamic resistance, heat balance challenges, nugget growth, machine types and power supplies, and electrodes. Subsequent chapters address challenges and approaches to important topics of welding advanced high-strength steels, such as DP, TRIP, TWIP, and Press Hardening Steel, as well as aluminum alloys. Welding issues associated with the various coatings used on these steels are addressed. The final chapters are dedicated to weld quality, monitoring, testing, computational modeling, and common automotive production issues such as the welding of multiple sheet stack-ups and a brief overview of associated codes and standards. The second edition includes updated chapters and additional information, such as expanded information on welding aluminum to steel, a new section on alternative welding and joining methods, and updates on monitoring and control as well as welding issues associated with the latest advanced high-strength steels.

This textbook introduces the reader to the development and qualification of arc welding procedures and personnel to industry codes and standards. The mechanics of using welding standards, how to address their requirements, and their relationship with other standards are explained. The reader will gain a working knowledge of common welding standards including a review of welding processes variables, the inspection and testing of welds, and their acceptance criteria. The reader will develop a basic understanding of:Common arc welding standardsWelding related documentationThe welding procedure development & qualification processEssential, non-essential, & supplementary essential variables for arc welding processesThe requirements for the inspection & testing of weld qualification couponsPurpose, intent, & compliance of a Welding Procedure Specifications (WPS)Purpose, intent, & compliance of a Procedure Qualification Records (PQR)The welder/operator performance qualification processPurpose, intent, & compliance of a Welder Performance Qualification Record (WPQR)This textbook was written for use in an undergraduate course in Welding EngineeringAlthough the book is aimed at Welding Engineering students, it should also serve as a useful guide to other engineers, technicians, and specialists who are working in the field of welding and are seeking how to apply relevant codes and standards to qualify welding procedures and personnel. While the book focused primarily on the common arc welding processes using AWS B2.1 and ASME BPVC Section IX, the principles discussed will apply to most welding processes in general and most welding qualification standards.
