To help operators achieve success, ESAB has produced an instructional video on Coreshield 71T-8 OS featuring techniques for welding in the vertical up (3G), vertical down, and 6G positions.ĮSAB will initially offer Coreshield 71T-8 OS wire in a diameter of 2 mm (5/64 th in.) on 200 mm (8 in.) plastic spools. “Compared SMAW, this flux-cored wire offers the productivity benefits of a continuous process and deposition rates of up to 2.3 kg/hr with a 2 mm wire.”įarrow notes that, compared to gas-shielded flux-cored wires, the AWS 71T-8 (EN ISO 17632-A) class of self-shielded wires requires different equipment configurations, parameter settings, and techniques. “Coreshield 71T-8 OS offers excellent arc characteristics and high welder appeal,” says Neil Farrow, Global Product Manager – Cored Wires, ESAB. As-welded mechanical properties include a Charpy V Notch strength of up to 172J (127 ft.-lb.) at -40 o C and typical tensile strength of 521 MPa (76 ksi). It features a diffusible hydrogen content lower than 8ml/100g and provides excellent low-temperature impact toughness. – ESAB Welding & Cutting Products has globally introduced Coreshield 71T-8 OS, self-shielded flux-cored wire for all-position welding of critical structural applications, such as TKY joints in offshore construction, pipe structures, bridges and storage tanks.
