Vinoo Kumar is a Mechanical Engineer with almost 20 years experience in ultrasonic plastic welding. He makes good use of that experience to produce this highly-detailed yet accessible book, which is published privately by his own company. For the newcomer he covers the basic principles, systems specification and safety without assuming any prior knowledge, and there is also a useful glossary. The main subject of the book, plastic welding, is covered in great detail - including materials selection, joint design, equipment selection, tooling design and a comprehensive troubleshooting guide. An excellent introduction to the subject.

This book is now available as a free download from the author's website.
