Abstract
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.
