The research on intelligent and automatic welding process information monitoring has been getting more concern, within the rise of intelligent manufacturing industry. The important step for the realization of intelligent welding technology is to obtain and analyze the dynamic information of the welding process, and to correspond, quantify and model the characteristics of all kinds of information with the weld pool state. Besides visual sensing technology, the acoustic signal is the most popular feature for automatic welding manufacturing. The book gave a full introduction of all the research on arc sound signal, such as sound source mechanism, classification, feature extraction, modeling and etc.
