Study on Arc and Drop Transfer Behaviors of DCEN MAG Welding

Abstract:

By means of the high speed camera, the arc and drop transfer behaviours of direct current electrode negative MAG welding process are researched. The influences of luminous arc ball on the stability of MAG welding process are analyzed. On this basis, the process interval of DCEN MAG welding is determined. And the influences of wire polarity on wire melting coefficient are compared. By using the shield gas 98%Ar + 2%O₂, the stable drop transfer manner can be divided into two kinds: dropwise transfer with low current, and streaming transfer with high current.
