Metal wire offers high-impact strength at low temperatures

March 30, 2010

As a complement to its Fabshield® XLR-8™ all-position welding wire, Hobart Brothers now offers the Fabshield XLNT-6™ self-shielded flux-cored wire for flat and horizontal welding applications that require impact toughness properties. Designed for use on structural steel weldments and bridge construction, the wire (AWS classification E70T-6) also is suitable for heavy equipment repair applications, as well as ship and barge construction. It features high deposition rates and excellent arc stability, the company reports.

The wire's impact strength at low temperatures (25 ft/lbs at -20 degrees F) helps resist cracking in applications subject to severe weather. The wire also features a fast-freezing, easy-to-remove slag to prevent slag entrapment.

The wire provides a tensile strength of 87,200 PSI with a yield strength of 66, 250 PSI, and it requires no shielding gas, which makes it highly portable for outdoor welding.

Currently, the wire is available in 3/32 and 5/64-in. dia. in a 25-lb. vacuum-sealed package or a 50-lb. coil. Both wires conform to AWS A5.20 requirements and can be used for single- or multi-pass welding. The 3/32-inch diameter meets the D designator also, which makes it usable for AWS D1.8 Demand Critical welds.
