Abstract

The data obtained for the variation of the melting rate and voltage in CO₂ welding with the change of the electrode extension are analysed. The dependences of the mean resistance of the unit length of the extension, the increase of the melting factor and the arc voltage on the electrode wire diameter are determined. The appropriate approximating dependences are derived. The average value of the melting factor in the reverse polarity arc at zero extension is determined.
