Overview

The development and introduction of new advanced materials has posed a serious welding challenge. Primarily based on experience and being as much an art as a science, the traditional wisdom for spot welding mild steels cannot be directly applied to new materials such as high strength steels and aluminum alloys. This book builds a solid foundation that will allow readers to deal with a variety of problems in resistance and other welding processes. In addition to an in-depth treatment of the fundamentals of resistance welding, it thoroughly examines its application and summarizes state-of-the-art research results and recent developments in resistance welding.

Reviews

[this book] will almost certainly find its way into the library of anyone who needs or wants to understand the physics behind resistance spot welding! [It offers] a detailed analysis of the physics involved in the resistance welding process that is, for the most part, remarkably easy to understand. This astounding feat is achieved through a novel exploitation of the differences in the way that aluminum and steel react during the resistance welding process. By dealing with the two materials in tandem, the authors are able to clearly show unique responses to the same welding variable. They have also reinforced their methodical explanations with nearly 300 original graphics!to reinforce concepts... [and] the material is well indexed so the book can be used as a quick reference. For both the student and process user, there is a lot of basic information presented in an easy-to-read fashion! For theoretical studies or laboratory work, there is a bounty of information beyond the excellent compilation of reference materials. It might be too soon to proclaim this work as historically significant, but it seems a virtual certainty that it will be viewed as such. In any case, the authors have certainly done a great service to the resistance welding industry. --David Beneteau, CenterLine Ltd., Windsor, Ontario, Canada, 2006
