S281612-058 - Hobart Fabcor 90 Metal-Cored Wire, 0.045, 1000lb Drum

Technical Overview of Hobart Fabcor 90 Metal-Cored Wire

The Hobart Fabcor 90 is a premium metal-cored welding wire designed for the fabrication of high-strength, low-alloy steels. Classified under AWS A5.28 as E90C-K3, this consumable is engineered to deliver weld deposits with a minimum tensile strength of 90,000 psi, making it suitable for critical applications requiring robust structural integrity. The wire features a 0.045-inch diameter and is supplied in a substantial 1000 lb Rx-Pk (Exacto-Pak) drum, a packaging format specifically intended to support high-volume manufacturing environments by drastically reducing the frequency of spool changes and associated downtime.

Technically, the Fabcor 90 excels in providing high deposition rates and transfer efficiencies that surpass traditional solid wires. It is formulated to operate with a shielding gas mixture of 75-95% Argon and a balance of Carbon Dioxide. This gas composition, combined with the wire's chemical makeup, produces a stable, smooth arc with minimal spatter generation. The resulting weld beads exhibit excellent wetting characteristics and a flat profile, which reduces the need for post-weld grinding or cleanup. Furthermore, the wire is designed to provide deep penetration, ensuring sound fusion in thicker base materials often found in heavy equipment and shipbuilding sectors.

Mechanical properties are a key highlight of the Fabcor 90. It offers impressive Charpy V-Notch (CVN) impact toughness values at low temperatures (typically down to -40°F/-40°C), which is essential for equipment operating in harsh environments. The wire is suitable for both single and multiple pass welding in the flat and horizontal positions. The 1000 lb bulk packaging is particularly advantageous for automated or robotic welding cells, as well as continuous manual operations, ensuring consistent wire feeding and maximizing arc-on time. This product is an optimal choice for industries demanding high throughput and stringent quality standards in joining high-strength steels.
