Abstract
The invention relates generally to welding and, more specifically, to electrodes for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). In one embodiment, a tubular welding wire includes a sheath and a core. The core includes a carbon source and a potassium source that together comprise less than 10% of the core by weight. Furthermore, the carbon source is selected from the group: carbon black, lamp black, carbon nanotubes, and diamond.
