The offered method is valid for the electrode stickout area, i.e. from the nozzle inlet to stickout adjacent to the droplet. Expressions for determination of current values of voltage drop in the electrode stickout length as functions of temperature and relations between the current length of electrode stickout and temperature at the end of the given area of stickout are presented.
Keywords: arc welding, CO2, electrode stickout, method of calculation, voltage drop, temperature, investigations, approximation
