Novel classification method of metal transfer modes in gas metal arc welding by real time input electrical impedance
Source abstract
Abstract
This paper presents an online, accurate and easy to use method for metal transfer mode classification using the input electrical impedance of arc welding as the signature. The records of the input electrical impedance are obtained by processing the welding voltage and current signals picked up at the output terminal of a welding machine. Similar to a typical linear electrical circuit consisting of a resistor, an inductor and a capacitor connected in series, the real and imaginary part of the input electrical impedance represents the combination of these electrical elements in the arc welding. Their variations directly reflect the switching among the metal transfer modes. A few experiments were conducted to confirm the above working principle and correlations between the input electrical impedance of arc welding and metal transfer. The results were then used to develop a method for online classification of metal transfer modes.
