Metal transfer controlled pulsed welding process

Abstract

A method of controlling a pulsed welding process, in which an electrode tip of a consumable electrode is advanced toward a workpiece, comprises: generating a pulsed current waveform having repetitive cycles; supplying the pulsed current waveform to the electrode tip to strike an arc on the workpiece during each cycle, wherein a cycle of the repetitive cycles includes: a pulse forming period that includes a forming pulse to form a droplet at the electrode tip, wherein the forming pulse includes a first peak that has a first peak duration; and a pulse detachment period that includes a detachment pulse separated from the forming pulse and configured to transfer the droplet from the electrode tip to the workpiece, wherein the detachment pulse includes a second peak that has a second peak duration that is less than the first peak duration.
