S243519-002 - Hobart Fabco 115 1/16" Flux-Cored Wire 60lb Coil

Technical Overview of Hobart Fabco 115

The Hobart Fabco 115 is a premium gas-shielded flux-cored wire designed for the welding of high-strength low-alloy (HSLA) steels. Engineered with a basic slag system, this wire is formulated to meet the rigorous demands of quenched and tempered steels such as ASTM A514, A517, and HY-100. The 1/16-inch diameter provides excellent deposition rates for heavy plate fabrication, while the 60lb coil packaging ensures extended run times in industrial settings.

One of the defining characteristics of the Fabco 115 is its low hydrogen weld deposit capability. Hydrogen-induced cracking is a significant concern when welding high-strength materials; the basic slag formulation of Fabco 115 actively assists in reducing diffusible hydrogen levels (typically meeting H4 requirements), thereby significantly mitigating the risk of cold cracking in the heat-affected zone (HAZ). This makes it an essential consumable for critical structural welds where integrity cannot be compromised.

Metallurgically, the wire deposits weld metal with tensile strengths exceeding 110,000 psi, matching the mechanical properties of T-1 and similar steel grades. It exhibits excellent impact toughness at sub-zero temperatures, ensuring ductility and resistance to brittle fracture in harsh operating environments. The wire is designed for use with either 100% CO2 or a 75% Argon / 25% CO2 shielding gas blend, offering flexibility depending on the specific procedure qualification and desired arc characteristics. While basic slag wires typically operate in the globular transfer mode, Fabco 115 is optimized for stability and bead profile control in flat and horizontal positions.

This product is supplied in a 60lb coil, requiring a suitable wire feeder adapter. It is ideal for single and multiple pass applications in heavy manufacturing, where deep penetration and superior fusion are required to meet AWS D1.1 and other structural codes.
