The Hobart Fabshield 4 is a high-performance, self-shielded tubular wire designed specifically for heavy-duty industrial applications where deposition rates and efficiency are paramount. Classified as AWS E70T-4, this wire is engineered to deposit weld metal rapidly, making it an ideal choice for the fabrication of heavy machinery, large construction components, and structural steel assemblies. The 5/64-inch diameter offers a significant step up in deposition potential compared to smaller diameter wires, allowing for substantial productivity gains in flat and horizontal fillet welds.
One of the primary technical advantages of the Fabshield 4 is its chemical formulation, which provides excellent sulfur tolerance. This feature significantly reduces the risk of hot cracking, a common issue when welding thick sections or steels with varying impurity levels. The wire operates on Direct Current Electrode Negative (DCEN), producing a globular transfer that ensures deep penetration and fusion. The slag system is designed to be self-peeling or easily removable, minimizing post-weld cleanup time and facilitating faster multi-pass operations.
Supplied in a 50 lb coil, this product is intended for industrial wire feeders capable of handling larger bulk packaging. The absence of an external shielding gas requirement simplifies logistics on large jobsites, particularly in outdoor environments where wind can disrupt gas coverage. This makes the Fabshield 4 a strategic choice for barge building, field construction, and heavy equipment repair where maintaining a gas shield is impractical. The wire delivers consistent mechanical properties, with typical tensile strengths exceeding 80,000 psi, ensuring structural integrity in demanding load-bearing applications.
For procurement and operations managers, the Fabshield 4 represents a balance of speed and reliability. Its ability to handle multiple pass applications without inter-pass cleaning issues (provided slag is removed) allows for continuous workflow in erecting heavy steel structures. It is a staple consumable for sectors requiring high-volume metal deposition without the logistical burden of gas cylinders.
