This book gives a full picture of the welding quality real-time control via arc sound information. This book presents all aspects of acoustic signal research during the welding dynamic process from the last five years. It also offers valuable and practical strategies for achieving the real-time control of welding quality via arc sound signal. Researchers, scientists, and engineers who have interests in intelligent welding could acquire intensive view and experiment procedures from the book.

Dr. Na Lv received her Ph.D. degree in Materials Processing Engineering from School of Materials Science and Engineering, Shanghai Jiao Tong University, in 2014. She currently worked as an assistant research fellow in School of Electronic information and electrical engineering, Shanghai Jiao Tong University.
