Hobart Fabco 115 .045 High-Strength Flux-Cored Wire 33lb

Heavy-Duty Welding with Hobart Fabco 115 .045" Wire

Hobart Fabco 115 is the professional's choice for joining high-yield strength steels in heavy industrial environments. This gas-shielded flux-cored wire is classified as an E110T5-K4 (depending on gas), indicating its capability to produce welds with a minimum tensile strength of 110,000 psi. It is the go-to consumable for fabricators working with T-1, HY-80, HY-100, and other quenched and tempered steels used in the manufacture of heavy machinery. The wire's formulation is distinct because of its basic slag system, which functions similarly to a lime-based coating on a stick electrode, acting as a powerful scavenger of impurities to produce clean, sound weld metal.

Fabricators choose Fabco 115 for its robust mechanical properties. In applications involving earthmoving equipment, agricultural machinery, and crane fabrication, welds are subjected to immense dynamic loads and fatigue. The Fabco 115 excels here by offering superior elongation and Charpy V-Notch impact values, reducing the risk of brittle failure. The wire is capable of both single and multiple pass welding, making it versatile for filling large bevels on thick plate sections. While it requires a bit more operator skill than standard rutile wires due to the globular transfer and fluid puddle, the resulting weld quality is unmatched for high-strength applications.

This 33lb spool of .045" wire is optimized for DCEP polarity and performs best in the flat and horizontal positions. It is highly recommended to ensure proper preheat and interpass temperatures are maintained when welding the high-strength base materials this wire is designed for, to fully realize the crack-resistant benefits of the low-hydrogen deposit. With Hobart Fabco 115, you get the assurance of radiographic quality welds that meet the stringent requirements of the mining, construction, and heavy fabrication sectors.
