S289343-008 - Hobart SubCOR EM13K-S MOD 1/8" Submerged Arc Wire - 600lb Drum

Technical Overview of Hobart SubCOR EM13K-S MOD

The Hobart SubCOR EM13K-S MOD is a premium composite electrode designed for the submerged arc welding (SAW) process. Engineered to meet the rigorous demands of heavy industrial fabrication, this 1/8-inch diameter wire offers a chemical composition that aligns with the AWS A5.17 EM13K classification for solid wires, yet it utilizes a composite (metal-cored) construction. This unique structure allows for enhanced deposition characteristics and tailored alloy additions that stabilize mechanical properties under varying welding conditions.

One of the primary technical merits of the SubCOR EM13K-S MOD is its resilience to high heat inputs. In many submerged arc applications, particularly those involving thick sections of carbon steel such as wind tower manufacturing or pressure vessel fabrication, high amperage and voltage parameters are necessary to achieve productivity goals. Standard wires may suffer from degraded mechanical properties, specifically toughness, under these thermal cycles. However, this modified electrode is formulated to maintain excellent impact toughness and tensile strength even when heat inputs are elevated, ensuring code compliance and structural reliability.

This product is supplied in a substantial 600 lb drum, designed for automated or semi-automated environments where downtime for spool changes must be minimized. It is suitable for both single-pass and multi-pass welding operations on non-alloyed and fine-grain steels. When paired with the appropriate Hobart flux, the SubCOR EM13K-S MOD delivers a stable arc, consistent bead profile, and slag that is easily removed, streamlining the post-weld cleaning process. It is an ideal choice for industries requiring high-integrity welds on critical infrastructure components.
