522241025H - Hobart SubCOR SL 742 3/32" Seamless SAW Wire, 55lb Coil

Tackle Critical Welds with Hobart SubCOR SL 742

When your project demands the highest strength and reliability, Hobart SubCOR SL 742 delivers the performance professional welders trust. This 3/32" seamless cored wire is built for the submerged arc welding (SAW) process, specifically designed to tackle high-strength steel projects where failure is simply not an option. Whether you are welding crane components, vehicle frames, or pressure vessels, this wire provides the 100 ksi yield strength needed to ensure your welds hold up under immense stress and heavy loads.

The "seamless" difference is a game-changer for shop productivity and weld quality. Because the wire is manufactured as a sealed tube rather than a folded strip, it does not absorb moisture from the air. This means you don't have to worry as much about hydrogen cracking, even in humid shop environments or if the wire has been stored for a period of time. For the welder, this translates to peace of mind and fewer repairs. The wire runs clean and smooth, with a high-quality copper coating that improves feedability and electrical contact, reducing the frustration of burn-backs, arcing in the tip, or erratic wire feeding behavior.

SubCOR SL 742 is a metal-cored wire, which offers significant advantages over solid wire in submerged arc applications. You get higher deposition rates, meaning you can lay down more metal in less time, speeding up long joint runs on girders or tanks. The arc characteristics are typically smoother, and the wetting action at the toes of the weld is superior, reducing the need for grinding or rework. It is designed to work seamlessly (pun intended) with industrial fluxes to create slag that lifts easily, leaving a professional, high-quality bead appearance that passes inspection the first time.

Packaged in a 55lb coil, this wire is ready for continuous production work. It is ideal for multi-pass welding on thick sections found in the transportation, power generation, and oil & gas industries. If you are looking to upgrade your submerged arc process for high-strength steels, the Hobart SubCOR SL 742 offers the perfect balance of weldability, mechanical strength, and low-hydrogen safety. It allows you to push your parameters for maximum efficiency while maintaining the strict code requirements often found in structural and pressure vessel work.

Whether you are repairing heavy castings or fabricating new structural components, this wire gives you the edge in both speed and quality. Trust Hobart's expertise in cored wire technology to keep your arc on and your production moving forward.
