Resistance Spot Welding

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.

Covers welding of modern advanced high-strength steels, coated steels, and aluminum alloys Emphasizes Resistance Spot Welding fundamental concepts and equipment Addresses common production issues, such as welding of multiple sheet stack-ups and electrode wear

Dr. David Phillips is a Professor of Practice in the Welding Engineering program at The Ohio State University. After completing his Master's degree in Welding Engineering in 1986, he spent approximately 20 years in industry, with most of his experience in the aerospace and automotive sectors. David then earned his Ph.D. in Welding Engineering and began teaching at Ohio State in 2008 where he now teaches a variety of welding processes and weld metallurgy courses from sophomore to graduate level. David is a licensed Professional Engineer (P.E.) in Welding Engineering, an International Welding Engineer (I.W.E.), and was a Certified Welding Inspector (C.W.I.) for 12 years. He is also the author of a recently published textbook titled Welding Engineering: An Introduction.
