Joining : Understanding the Basics

Extending ASM's Understanding the Basics series into fabrication technologies, this book is an introduction to the most important industrial joining methods: welding, brazing, soldering, fastening, and adhesive bonding. It addresses metallurgical issues that must be understood during welding, and provides an overview of issues to consider when joining systems of materials that are the same, similar, or different.
