S295743-020 - Hobart SDX EM14K Submerged Arc Wire 1/8" 55lb Coil

Hobart SDX EM14K Submerged Arc Welding Wire

The Hobart SDX EM14K is a premium copper-coated solid carbon steel wire engineered specifically for the submerged arc welding (SAW) process. This wire is manufactured to meet the rigorous demands of heavy industrial fabrication, offering a precise chemical composition that includes moderate levels of manganese, silicon, and titanium. This specific alloying approach is designed to significantly enhance the weld metal's mechanical properties, particularly its impact toughness at lower temperatures. For industries where structural integrity is paramount, such as bridge building and pressure vessel manufacturing, the SDX EM14K provides the reliability and consistency required for code-compliant welds.

One of the standout technical characteristics of this wire is its ability to maintain improved Charpy V-Notch (CVN) toughness even when subjected to high heat input welding procedures. This makes it an excellent choice for thick-section welding where deposition rates and heat management are critical factors. The copper coating on the wire not only improves electrical conductivity at the contact tip but also aids in feeding capability, reducing wear on liners and tips while preventing corrosion during storage. The wire is versatile enough for both single-pass and multiple-pass welding operations when paired with the appropriate neutral or active fluxes, depending on the specific application requirements.

In the context of industrial supply and MRO, the Hobart SDX EM14K represents a high-performance consumable for large-scale fabrication shops. It is categorized under AWS A5.17 as an EM14K class wire, suitable for welding mild and low-alloy steels. Its formulation helps mitigate the risk of cracking in heavy weldments and ensures a smooth bead profile with excellent slag detachment when used with compatible flux systems. This 55lb coil packaging is standard for industrial wire feeders, ensuring long run times and reduced downtime for spool changes.
