Technical Performance of Hobart Fabshield 21B

Hobart Fabshield 21B is a general-purpose, self-shielded flux-cored wire conforming to AWS E71T-11 specifications. This 1/16-inch diameter wire is supplied on a 33-pound spool and is specifically formulated for high-deposition welding on mild and coated steels. As an E71T-11 class wire, it is designed to operate on DCEN (Direct Current Electrode Negative) polarity, providing a smooth arc characteristic that is manageable for operators of varying skill levels. It is an ideal solution for applications where gas shielding is unavailable or impractical, such as field erection and outdoor repair work.

The chemical composition and flux formulation of Fabshield 21B allow it to excel in welding galvanized and zinc-coated steels, minimizing porosity and burn-through that can occur with solid wires. It is capable of bridging gaps effectively and is rated for both single-pass and multi-pass welding operations. The wire offers excellent mechanical properties for general structural applications, ensuring weld integrity even in less-than-ideal surface conditions. Its all-position capability ensures that vertical and overhead welds can be executed with good bead contour and fusion.

Welders will appreciate the practical benefits of the Fabshield 21B, including its easy slag removal and low spatter levels relative to other self-shielded wires in its class. It is a staple consumable for industries ranging from agricultural equipment manufacturing to barge construction and general structural steel fabrication. By eliminating the need for shielding gas equipment, it simplifies the welding setup and reduces overall operational costs while maintaining high standards of weld quality.
