The disclosure relates generally to welding and, more specifically, to tubular welding wires for arc welding processes, such as Gas Metal Arc Welding (GMAW), Flux Core Arc Welding (FCAW), and Submerged Arc Welding (SAW). The tubular welding wire includes a metal sheath surrounding a granular core. The metal sheath includes greater than approximately 0.6% manganese by weight and greater than approximately 0.05% silicon by weight. Further, the metal sheath has a thickness of between approximately 0.008 inches and approximately 0.02 inches.

Tubular welding wire with a thinner sheath for improved deposition rates

The present systems and methods relate generally to the field of welding systems, and particularly to flux-cored arc welding systems with self-shielded electrodes (FCAW-S). In an embodiment, a tubular welding wire includes a core and a sheath disposed around the core. Further, the tubular welding wire includes greater than approximately 2.4% glassy slag promoter by weight.

Root pass welding solution

A tubular welding wire includes a granular core and a metal sheath encircling the granular core. Furthermore, the metal sheath includes at least approximately 0.3% manganese by weight and at least approximately 0.05% silicon by weight.
