摘要： Systems and methods for affecting an appearance of a deposited weld bead by modulating one or more welding parameters. For example, an electrode negative portion of a welding output current may be modulated to affect the appearance of a deposited weld bead. Furthermore, a wire feed speed of a welding electrode may be synergistically modulated with an electrode negative portion of a welding output current to affect a deposited weld bead appearance. Two or more welding processes may be interleaved with each other at a specified modulation frequency to affect a deposited weld bead appearance. One or more welding parameters may be modulated based on a welding travel speed to provide a consistent appearance of a deposited weld bead.

摘要： Systems and methods to affect heat input to a weld and, therefore, an appearance of a deposited weld bead by modulating a mixing ratio of shielding gases and/or one or more welding parameters. For example, a mixing ratio of two different shielding gases from two sources of shielding gases may be modulated to affect the appearance of a deposited weld bead. The modulation frequency may be based on a selected travel speed of a welding tool. Furthermore, a wire feed speed of a welding electrode may be synergistically modulated with the shielding gases to affect a deposited weld bead appearance. Other welding parameters may be synergistically modulated with the shielding gases to affect a deposited weld bead appearance.

摘要： Systems and methods for facilitating the starting and stopping of arc welding processes, as well as for responding to events in mid-weld. Specially designed signals may be briefly applied between a welding electrode and a welding workpiece at the start and end of a welding process to gracefully and properly start and stop a weld. Furthermore, specially designed signals may be briefly applied in the middle of a welding process, if determined events occur, to counter the undesirable effects of the events.

摘要： A welding system comprises a welding power source that provides an alternating current in a selected wave form having a set of positive and negative portions, the negative portion consisting of a peak, tailout, and background phase, and the positive portion consisting of a peak, tailout, and background; wherein the power source provides an upward ramping current during the pinch and detachment phase, switches to an electrode negative current during the negative peak, tailout, and background phases, and switches to a subsequent electrode positive portion; wherein, the positive portion may repeat prior to the next shorting event.
