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. Her research interests focus on Intelligent welding, multi-information processing, welding process modeling, machine learning, intelligent tea picking robot, and image recognition.

Dr. Shanben Chenreceived his BS degree in industrial automation from Dalian Railway Institute (Dalian Jiao Tong University) in 1982, and received his MS and PhD in control theory and application from Harbin Institute of Technology, China, in 1987 and 1991, respectively. He worked as a postdoctoral fellow at the National Key Laboratory of Advanced Welding Production of China in Harbin Institute of Technology (HIT) from 1993 to 1995, and as a professor from 1995 to 2000.

From 2000 to present, he has served as the Special Professor, Cheung Kong Scholar Program of the Ministry of Education of China& Li Ka Shing Foundation, Hong Kong, and engaged at Shanghai Jiao Tong University, China, where he is also director of the Intelligentized Robotic Welding Technology Laboratory. Prof. Chen has also been a visiting professor at the University of Western Sydney (UWS) in connection with the ARC Linkage collaboration since 2009.

Currently, Prof. Chen is a senior member of the IEEE; a member of the American Welding Society; Chair of the Robotics& Automation Committee of the Chinese Welding Society (CWS); Deputy Secretary-General of the Chinese Welding Society; and a standing member of the Board of Directors, CWS.
