S281215-058 - Hobart Fabcor 80D2 .052 Metal-Cored Wire 1000lb Drum

Technical Overview: Hobart Fabcor 80D2

The Hobart Fabcor 80D2 is a gas-shielded metal-cored wire conforming to AWS A5.28 specifications, typically classified as E80C-D2 or E90C-D2 depending on the specific heat input and cooling rates. This .052-inch diameter wire is engineered for the welding of high-strength, low-alloy (HSLA) steels, utilizing a Manganese-Molybdenum alloying system to achieve superior mechanical properties. It is designed for use with a shielding gas mixture of 98% Argon and 2% Oxygen, which promotes a spray transfer mode that is smooth, stable, and virtually spatter-free.

Metallurgical Properties and Performance

The core composition of Fabcor 80D2 is optimized to provide high tensile strength (typically in the 90-100 ksi range) and excellent Charpy V-Notch impact toughness, even at lower temperatures. This makes it a critical consumable for applications involving ASTM A514, A710, and similar high-yield steels often found in heavy machinery and structural components. The metal-cored design allows for higher current densities than solid wires of the same diameter, resulting in deeper penetration profiles and significantly higher deposition rates. This is particularly advantageous in fillet and groove welds on thick sections where heat input control and fusion are critical.

Operational Characteristics

Welders will appreciate the excellent bead wetting action of the Fabcor 80D2, which helps eliminate cold lap and lack of fusion defects, especially at the toes of the weld. The slag system is minimal, often appearing as small islands of silicon that are easily removed, facilitating multi-pass welding without extensive inter-pass cleaning. The wire is designed for DCEP (Direct Current Electrode Positive) polarity and operates best in the flat and horizontal positions.

Bulk Packaging for Automation

Supplied in a 1000 lb (453 kg) X-Pak drum, this product is tailored for high-volume manufacturing environments, including robotic automation and hard automation cells. The precision winding and payout system of the X-Pak ensures consistent wire feeding with minimal drag, reducing the risk of arc instability or burn-backs caused by feed issues. This bulk format minimizes downtime associated with spool changes, maximizing overall equipment effectiveness (OEE) in production lines.
