71232414FH - Hobart SDX EM13K 1/8-inch SAW Wire 1000lb Drum

Technical Overview: Hobart SDX EM13K Submerged Arc Wire

The Hobart SDX EM13K is a premium-quality, solid carbon steel wire designed specifically for the submerged arc welding (SAW) process. Formulated with a medium manganese and low silicon composition, this wire meets AWS A5.17/A5.17M classifications, making it a standard choice for industries requiring rigorous code compliance and consistent mechanical properties. The 1/8-inch (3.2mm) diameter is optimized for heavy deposition rates, suitable for welding plate thicknesses common in structural steel, bridge construction, and pressure vessel fabrication.

Chemically, the EM13K classification indicates a wire that offers a balanced approach to deoxidation. The medium manganese content enhances the tensile strength of the weld metal, while the lower silicon content makes it particularly versatile when selecting fluxes. It performs exceptionally well with neutral fluxes for multi-pass applications where impact toughness is critical, as well as with active fluxes for single-pass welds on slightly rusty or mill-scaled plates. The copper coating on the wire surface is strictly controlled to ensure excellent electrical conductivity at the contact tip, reducing resistance heating and ensuring stable arc characteristics even at high currents.

This specific SKU is supplied in a 1000 lb (453.6 kg) drum, designed for high-volume manufacturing environments. The bulk packaging significantly reduces downtime associated with spool changes, making it ideal for automated systems, beam lines, and dedicated welding stations. The wire is precision-wound to ensure tangle-free payout, which is critical for maintaining continuous operations in automated submerged arc setups. Storage and handling should follow standard low-hydrogen practices to maintain the integrity of the wire surface and prevent porosity.
