Key Technologies of Intelligentized Welding Manufacturing

This book presents the recent research results of the application of arc spectrum in the welding process. It sheds light on the fundamentals of monitoring welding quality using arc spectral information. By analyzing the topic both from a global and local perspective, it establishes a knowledge base of features characterizing welding statuses. Researchers, scientists and engineers in the field of intelligent welding can benefit from the book. As such, this book provides valuable knowledge, useful methods, and practical algorithms that are applicable in real-time detection of welding defects.

Focuses on the application of the welding arc spectrum in monitoring the process and the quality of arc welding Offers feature extraction algorithms for different kinds of welding defects Presents useful methods to develop on-line detection and improve the quality of the welding process
