S289619-058 - Hobart Fabcor Edge D2 1/16 Metal Core Wire 1000lb Drum

Technical Overview of Hobart Fabcor Edge D2

The Hobart Fabcor Edge D2 is a premium low-alloy metal-cored welding wire designed to meet the rigorous demands of high-strength fabrication. Engineered with a precise chemical composition, this wire produces a weld deposit containing approximately 0.5% Molybdenum (Mo) and roughly 1.4% Manganese (Mn), aligning with the AWS A5.28 E90C-D2 classification. This specific metallurgy makes it an ideal choice for welding high-strength low-alloy (HSLA) steels where tensile strengths in the 90,000 psi range are required. The 1/16-inch diameter offers a substantial current-carrying capacity, allowing for high deposition rates that significantly outperform solid wires in flat and horizontal positions.

One of the defining technical characteristics of the Fabcor Edge D2 is its versatility in shielding gas selection. It operates effectively with mixtures ranging from 75-95% Argon with a Carbon Dioxide balance, as well as 95-98% Argon with an Oxygen balance. This flexibility allows welding engineers to tailor the arc characteristics and penetration profile to specific joint configurations. The metal-cored construction ensures a high current density at the sheath, resulting in a broad, spray-like transfer that provides excellent fusion and sidewall wetting. This is critical in heavy fabrication to mitigate defects such as cold lap, especially when welding thicker sections of pressure vessels or heavy equipment components.

The product is supplied in a 1000 lb Rx-Pk (Recyclable X-Pak), a bulk packaging solution designed for high-volume manufacturing environments. This packaging format reduces the frequency of spool changes, thereby increasing arc-on time and overall throughput. The wire is wound to ensure tangle-free feeding, which is essential for automated or robotic welding cells where feed interruptions can cause costly downtime. The Fabcor Edge D2 also exhibits low hydrogen levels, reducing the risk of hydrogen-induced cracking in sensitive alloy steels.

In terms of mechanical properties, the weld metal delivers consistent toughness and strength, maintaining integrity even in demanding service conditions. The slag formation is minimal and typically appears as small islands of silicon, which are easily removed, facilitating multi-pass welding without extensive inter-pass cleaning. This efficiency makes the Fabcor Edge D2 a technically superior option for structural, pipe, and transportation fabrication sectors requiring E90C-D2 specifications.
