Resumo: This paper presents a continuation of a study carried out on the use of the out-of-phase current pulses technology applied to the Double Wire MIG/MAG welding process with Insulated Potentials on welded coatings. In the first part it was reported how the level of out-phase pulsed current acts on arc configuration, droplet paths, bead finishing and arc stability. The objective now is to show the effect on the bead geometry caused by changes in arc and metal transfer. Beads were deposited on plate in a flat position and out-of-phase levels were varied. The results showed that, with the electrodes positioned side by side and mean currents below the transition current, the lag time between out-of-phase current pulses have a remarkable influence on the penetration profile of the weld bead.
