Drawing on state-of-the-art research results, Resistance
Welding: Fundamentals and Applications, Second Edition
systematically presents fundamental aspects of important processes
in resistance welding and discusses their implications on
real-world welding applications. This updated edition describes
progress made in resistance welding research and practice since the
publication of the first edition.
New to the Second Edition:
- Significant addition of the metallurgical aspects of materials
involved in resistance welding, such as steels, aluminum and
magnesium alloys, zinc, and copper
- Electric current waveforms commonly used in resistance welding,
including single-phase AC, single-phase DC, three-phase DC, and
MFDC
- Magnesium welding in terms of cracking and expulsion
- The effect of individual welding parameters
- 2-D and 3-D lobe diagrams
- New materials for the ultrasonic evaluation of welds, including
A-scan, B-scan, and in-line A-scan
The book begins with chapters on the metallurgical processes in
resistance spot welding, the basics of welding schedule selection,
and cracking in the nugget and heat-affected zone of alloys. The
next several chapters discuss commonly conducted mechanical tests,
the monitoring and control of a welding process, and the
destructive and nondestructive evaluation of weld quality. The
authors then analyze the mechanisms of expulsion a process largely
responsible for defect formation and other unwanted features and
explore an often overlooked topic in resistance welding-related
research: the influence of mechanical aspects of welding machines.
The final chapters explain how to numerically simulate a resistance
welding process and apply statistical design and analysis
approaches to welding research.
To obtain a broad understanding of this area, readers previously
had to scour large quantities of research on resistance welding and
essential related subjects, such as statistical analysis. This book
collects the necessary information in one source for students,
researchers, and practitioners in the sheet metal industry. It
thoroughly reviews state-of-the-art results in resistance welding
research and gives you a solid foundation for solving practical
problems in a scientific and systematic manner.
