Use of audible sound for on-line monitoring of gas metal arc welding process

[摘要] In this paper sound generated during the gas-metal arc welding process was studded. Experimental analyses of the acoustic signals have shown that there are two main noise-generating mechanisms, first having impulse form is arc extinction...
