<p>The invention relates generally to welding and, more specifically, to welding wires for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). In one embodiment, a tubular welding wire (50) includes a sheath (52) and a core (54), in which the sheath (52) includes less than approximately 0.06% carbon by weight. The core (54) includes a carbon source and a potassium source that together comprise less than 10% of the core by weight.</p> |
