S651529-002 - Hobart Fabco 115K3 3/32" Flux-Cored Wire - 60lb Coil

Hobart Fabco 115K3 3/32" Flux-Cored Wire Overview

The Hobart Fabco 115K3 is a premium 3/32-inch flux-cored welding wire designed specifically for joining high-strength, quenched, and tempered steels. Packaged in a substantial 60lb coil, this wire is engineered to meet the rigorous demands of heavy industrial fabrication where weld integrity is paramount. It carries the AWS classification E110T5-K3, indicating its suitability for materials requiring tensile strengths in the 110,000 psi range, such as ASTM A514 and A517 grades (often referred to as T-1 steels).

What sets the Fabco 115K3 apart is its basic slag system (T-5). Unlike rutile-based wires that prioritize operator appeal and all-position capabilities, this basic slag formulation prioritizes metallurgical quality. It produces weld deposits with exceptionally low diffusible hydrogen content (typically under 4ml/100g), which significantly reduces the risk of hydrogen-induced cracking—a critical factor when welding high-strength low-alloy (HSLA) materials. The wire offers superior impact toughness at low temperatures, ensuring the structural integrity of equipment operating in harsh environments.

This wire is versatile regarding shielding gas, operating effectively with either 100% CO2 or a blend of 75% Argon and 25% CO2. While the basic slag system generally limits welding to the flat and horizontal positions, it rewards the operator with deep penetration and excellent fusion. It is the consumable of choice for fabricating crane booms, heavy earth-moving equipment, shipbuilding structures, and other critical components where failure is not an option. Josef Gas provides this high-performance consumable to support your most challenging engineering projects.
