S225719-079 - Hobart Fabshield XLR-8 1/16" Self-Shielded Flux-Cored Wire

Technical Overview of Hobart Fabshield XLR-8

The Hobart Fabshield XLR-8 is a premium self-shielded flux-cored wire designed to meet the rigorous demands of critical structural applications. Engineered with a fast-freezing slag system, this wire provides exceptional operator appeal and weld pool control, particularly in vertical-up positions. It is formulated to produce weld deposits with excellent mechanical properties, specifically high impact toughness at low temperatures, making it a preferred choice for industries requiring AWS D1.8 Seismic Supplement compliance.

This 1/16-inch diameter wire operates on DCEN (Direct Current Electrode Negative) polarity and is classified under AWS A5.20 as E71T-8JD H8. The 'H8' designation indicates a diffusible hydrogen content of less than 8ml per 100g of weld metal, significantly reducing the risk of hydrogen-induced cracking in heavy structural steel sections. The wire's chemistry is optimized to deliver consistent arc stability and a flat bead profile, even when welding out of position at higher amperage settings.

One of the standout technical features of the XLR-8 is its deslagging capability. The slag is designed to be self-peeling or easily removable, which minimizes inter-pass cleaning time and improves overall throughput in multi-pass welding scenarios. The vacuum-sealed packaging (Vcsp) ensures the product remains moisture-free during storage and transport, preserving its low-hydrogen characteristics until the moment of use. This wire is suitable for welding ASTM A36, A572, and similar carbon steels found in bridge construction, shipyards, and offshore platforms.

By eliminating the need for external shielding gas, the Fabshield XLR-8 simplifies equipment setup and logistics, particularly in field erection environments. It provides deep penetration and fusion, ensuring structural integrity in demanding service conditions. The wire supports a wide range of operating parameters, allowing welding engineers and technicians to tailor procedures for specific joint configurations and plate thicknesses.
