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.
