Abstract
A CO2-shielded long arc welding stability increase technique is suggested, which is attainable by pulsed arc welding application. At pulse pile-up, power dispensing is carried out on the droplets melting, starting from the moment of droplet detachment, which is registered by the voltage spike at the arc space. This allows for keeping up equal sizes of the droplets, favours higher process stability and weld upgrading.
