Acoustic signal analysis for classification of transfer mode in GMAW by noncontact sensing technique

The objective in this paper is to investigate acoustic signal emitted during metal transfer in gas metal arc welding process (GMAW). Short circuit, globular transfer and spray transfer were classified by using dynamic microphone. Mode of metal transfer can be clearly classified and explained by usin...
