S650429-008 - Hobart Fabco 105D2 3/32-inch E100T5-K3 Flux-Cored Wire Drum

High-Performance High-Strength Flux-Cored Wire

The Hobart Fabco 105D2 is a premium gas-shielded flux-cored wire designed specifically for the welding of high-strength low-alloy (HSLA) steels. Formulated with a basic slag system, this wire is engineered to meet the rigorous demands of industries requiring welds with tensile strengths in the 100,000 psi (690 MPa) class. It carries the AWS classification E100T5-K3, indicating its suitability for critical structural applications where mechanical integrity and crack resistance are paramount. The 3/32-inch diameter is a heavy-duty size intended for high-deposition welding, allowing for significant productivity gains in heavy fabrication environments.

This product is supplied in a bulk 600 lb drum, making it an ideal choice for automated welding cells, robotic systems, or continuous hard automation stations where minimizing downtime for spool changes is essential for operational efficiency. The drum packaging ensures a consistent, twist-free feed of wire over long durations, which is critical for maintaining arc stability and weld quality in high-volume production settings. The wire is designed to operate with 100% CO2 shielding gas, which not only provides deep penetration profiles but also offers a cost-effective shielding solution compared to argon mixtures.

Metallurgically, the Fabco 105D2 excels in providing superior low-temperature impact toughness. The basic slag formulation assists in reducing the hydrogen content of the weld metal, thereby significantly lowering the risk of hydrogen-induced cracking (cold cracking), which is a common concern when welding high-strength quenched and tempered steels like T-1 or HY-80. This makes the wire particularly suitable for the fabrication of heavy earthmoving equipment, crane booms, offshore structures, and other dynamically loaded components that operate in harsh environments. Procurement managers and welding engineers can rely on the Fabco 105D2 for consistent mechanical properties that meet or exceed stringent industry specifications.

Storage and handling are critical for basic slag wires to maintain their low-hydrogen status. The 600 lb drum offers robust protection, but standard industrial practices for moisture control should be observed to ensure optimal performance. With its combination of high strength, excellent toughness, and bulk packaging efficiency, the Hobart Fabco 105D2 represents a top-tier solution for heavy industrial welding projects.
