Abstract
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.
