S650419-002 - Hobart Fabco 105D2 1/16" Flux-Cored Wire 60lb Coil

High-Strength Low Alloy Flux-Cored Wire

The Hobart Fabco 105D2 is a premium 1/16-inch flux-cored welding wire designed for demanding industrial applications requiring high tensile strength and superior toughness. Formulated with a basic slag system, this wire produces a low hydrogen weld deposit that is highly resistant to cracking, making it an excellent choice for critical structural repairs and fabrication. The wire is specifically engineered to join manganese-molybdenum steels and other low alloy high-strength materials.

Post-Weld Heat Treatment Capability

One of the standout features of the Fabco 105D2 is its ability to maintain high mechanical properties even after post-weld heat treatment (PWHT). Many standard flux-cored wires lose significant strength or toughness after stress-relieving heat cycles, but the 105D2 chemistry is balanced to retain a tensile strength in the neighborhood of 100,000 psi. This makes it indispensable for fabricating heavy wall pressure vessels, thick structural components, or castings that require stress relief to prevent service failure.

Operational Characteristics

Designed for use with 100% CO2 shielding gas, this wire offers deep penetration and reliable fusion. The basic slag system, while requiring more operator skill than rutile wires, rewards the welder with exceptional deposit cleanliness and mechanical integrity. It is particularly effective for the repair of manganese-moly castings found in mining and earthmoving equipment. The 60lb coil packaging is suited for industrial wire feeders in shop environments where long-run continuous welding is standard practice.

Technical Specifications

The wire typically meets AWS E100T5-D2 classifications (check specific lot conformance). It delivers a deposit composition rich in manganese and molybdenum, providing the hardenability and strength required for heavy-duty service. The 1/16" diameter allows for high deposition rates in the flat and horizontal positions, maximizing productivity on thick sections.
