S283715-002 - Hobart FabCO 803 0.052 Flux-Cored Wire 60lb Coil

Technical Overview of Hobart FabCO 803

The Hobart FabCO 803 is a premium gas-shielded flux-cored wire designed specifically to meet the rigorous demands of industries requiring high-strength welds in low-temperature environments. This 0.052-inch diameter wire, supplied in a substantial 60lb coil, is formulated for joining fine-grained steels and is particularly ideal for welding 2% Nickel steels. Its metallurgical composition ensures that the weld deposit maintains excellent Charpy V-Notch (CVN) toughness even at sub-zero temperatures, a critical requirement for structural integrity in arctic or deep-sea conditions.

One of the standout technical features of the FabCO 803 is its fast-freezing slag system. This characteristic significantly enhances the puddle control, allowing welders to perform single or multiple pass welds in all positions, including vertical-up and overhead, without sacrificing bead contour or quality. The wire is engineered to produce a stable arc with low spatter generation, which not only improves the operator's visibility and comfort but also reduces non-productive time spent on post-weld grinding and cleanup.

Versatility in shielding gas is another key benefit of this consumable. It operates effectively with either 100% Carbon Dioxide (CO2) or a mixture of 75-80% Argon and balanced CO2. This flexibility allows fabrication shops to optimize their gas selection based on availability, cost, or specific arc characteristic preferences. Whether utilized in the construction of offshore platforms, pipelines, or heavy earth-moving equipment, the FabCO 803 delivers consistent mechanical properties and reliable performance.

Applications and Metallurgy

The primary application for FabCO 803 revolves around projects where the base material is subject to high stress and low temperatures. The inclusion of nickel in the weld metal microstructure refines the grain and boosts impact resistance. This makes it the consumable of choice for the petrochemical industry, power generation facilities, and shipbuilding sectors where failure is not an option. The 60lb coil packaging is designed for industrial wire feeders, supporting longer continuous welding durations and reducing changeover downtime in high-volume production environments.
