S616529-084 - Hobart Tube-Alloy 861-S 3/32" Sub-Arc Hardfacing Wire Drum

Maximize Deposition with Tube-Alloy 861-S

For professional welders and automation operators tackling large-scale resurfacing projects, the Hobart Tube-Alloy 861-S offers a superior welding experience. This 3/32-inch metal-cored wire is formulated for the submerged arc process, delivering smooth, consistent beads with excellent slag release. If you are rebuilding crane wheels, mine car wheels, or heavy industrial rollers, this wire provides the smooth runnability you need to maintain high travel speeds without sacrificing bead quality. The metal-cored design allows for higher amperage utilization, meaning you can lay down more metal in less time compared to conventional solid wires.

The 600lb Auto-Pak is a game-changer for shop efficiency. Forget about stopping every few hours to swap out small spools; this bulk drum allows for long, uninterrupted welding cycles, which is essential when working on large circumference parts where stop-starts can introduce defects. The wire feeds smoothly from the drum, reducing the risk of burn-backs or bird-nesting in the drive rolls. The resulting weld deposit is a tough, martensitic steel that stands up to heavy metal-to-metal friction, ensuring that the parts you repair stay in service longer.

Post-weld finishing is often a concern with hardfacing, but the Tube-Alloy 861-S deposit can be machined with carbide tools, allowing you to bring parts back to precise dimensional tolerances. It is recommended to use this wire with a neutral flux to prevent altering the alloy's chemistry, ensuring predictable hardness and performance. With Hobart's reputation for quality consistency, you can trust the 861-S to perform identically from the top of the drum to the bottom, giving you the confidence to tackle critical buildup jobs with ease.
