OVERVIEW

Hobart Fabco 91K2-M: Premium High-Strength Flux-Cored Wire

The Hobart Fabco 91K2-M is a premier choice for industrial welding applications requiring high tensile strength and exceptional toughness, particularly in low-temperature environments. This .045-inch diameter gas-shielded flux-cored wire is engineered to meet the rigorous demands of heavy fabrication, offering a reliable solution for welding high-strength low-alloy (HSLA) steels. Packaged in a 33-pound vacuum-packed spool (VPSP), the wire is protected against moisture absorption, ensuring low diffusible hydrogen levels and reducing the risk of hydrogen-induced cracking in critical welds.

Designed for use with mixed shielding gas (typically 75% Argon and 25% CO2), the Fabco 91K2-M delivers a smooth, stable arc with minimal spatter, which significantly reduces post-weld cleanup time. Its fast-freezing slag system allows for excellent puddle control, making it suitable for welding in all positions, including vertical-up and overhead. This versatility is essential for complex structural projects where rotating the workpiece is not feasible. The wire's formulation includes roughly 1.5% nickel, which enhances its mechanical properties and ensures consistent impact toughness down to -40°F (-40°C).

Industries such as shipbuilding, offshore platform construction, and heavy equipment manufacturing rely on the Fabco 91K2-M for its consistency and performance. Whether used for single-pass or multi-pass applications, this wire produces X-ray quality welds with excellent bead appearance. By choosing Hobart's VPSP packaging, operators can trust that the product arrives in factory-fresh condition, ready for immediate high-quality deposition.

Key Industrial Benefits

  • Low Temperature Toughness: Meets strict impact requirements for harsh environments.
  • All-Position Capability: Fast-freezing slag supports vertical and overhead welding.
  • Moisture Protection: Vacuum packaging preserves wire integrity and low hydrogen status.
  • High Productivity: High deposition rates and easy slag removal improve throughput.

FAQ

This wire is designed for use with a mixed gas, typically 75% Argon and 25% CO2.

The AWS classification is E91T1-K2M-H4.

Yes, the Fabco 91K2-M has a fast-freezing slag that makes it suitable for all-position welding, including vertical-up and overhead.

The wire produces a weld deposit with a tensile strength in the range of 90,000 psi (90 ksi).

It comes in a Vacuum Packed Spool (VPSP) to protect against moisture. Once opened, it should be stored in a dry environment or a rod oven if necessary to maintain low hydrogen levels.

This wire operates on Direct Current Electrode Positive (DCEP), also known as DC+.

It is suitable for both single and multiple pass applications.

The wire contains approximately 1.5% Nickel to improve impact toughness at low temperatures.
