S295743-S66 - Hobart SDX EM14K 1/8" SAW Wire 660lb Drum

Technical Overview of Hobart SDX EM14K

The Hobart SDX EM14K is a premium quality solid welding wire designed specifically for the Submerged Arc Welding (SAW) process. Engineered to meet the rigorous standards of AWS A5.17 and ASME SFA 5.17, this wire falls under the EM14K classification. It is characterized by a medium manganese and silicon composition, enriched with a specific addition of titanium. This unique chemical formulation is critical for applications requiring robust deoxidation and resistance to porosity, particularly when welding over base materials that may exhibit light rust or mill scale.

With a diameter of 1/8 inch (3.2 mm), this wire is optimized for high-deposition welding in heavy fabrication environments. The inclusion of titanium acts as a powerful scavenger, helping to stabilize the arc and refine the microstructure of the weld metal. This results in a deposit that maintains high integrity and mechanical strength even under variable fit-up conditions. The wire is copper-coated, a standard feature in high-quality SAW wires, which serves dual purposes: it enhances electrical conductivity at the contact tip for stable arc initiation and maintenance, and it provides corrosion resistance to the wire surface during storage.

Packaged in a substantial 660 lb (approx. 300 kg) drum, the S295743-S66 SKU is tailored for industrial automation and continuous welding operations where downtime for spool changes must be minimized. The drum packaging ensures a straight payout (cast and helix control), which is vital for accurate wire placement in automated seams. This wire is compatible with a variety of neutral and active fluxes, allowing welding engineers to tailor the mechanical properties of the final weldment to specific project requirements, such as low-temperature impact toughness or high tensile strength.

Commonly utilized in the fabrication of structural steel, pressure vessels, and heavy machinery, Hobart SDX EM14K provides a reliable solution for single-pass and multi-pass welding. Its ability to produce smooth bead profiles with self-releasing slag (flux dependent) reduces post-weld cleaning time and improves overall productivity in the shop.
