ESAB Launches Self-Shielded Flux Cored Wire For Offshore, Construction, Pipe and Bridge Applications
August 13, 2021
Annapolis Junction, Md. – ESAB Welding & Cutting Products has globally introduced Coreshield 71T-8 OS, a 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. It features a diffusible hydrogen content lower than 8ml/100g and provides excellent low temperature impact toughness. As-welded mechanical properties include a Charpy V Notch strength of up to 172J (127 ft.-lb.) at -40o C and typical tensile strength of 521 MPa (76 ksi).
“Coreshield 71T-8 OS offers excellent arc characteristics and high welder appeal,” says Neil Farrow, Global Product Manager – Cored Wires, ESAB. “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.”
Farrow 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. 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.
ESAB will initially offer Coreshield 71T-8 OS wire in a diameter of 2 mm (5/64th in.) on 200 mm (8 in.) plastic spools. In the future, ESAB will offer additional wire diameters and a 300 mm (12 in.) spool option. The wire comes in a vacuum-seal package to prevent moisture absorption and preserve its low hydrogen content.
At ESAB, we exist to shape the future of welding and cutting. We connect fabricators with the widest range of products under our industry-leading brand portfolio with the latest technologies to solve virtually any industry challenge — then we back it up with our knowledge, experience and passion to help them be more productive than ever before
ESAB’s new Coreshield 71T-8 OS self-shielded flux cored wire offers excellent performance for all-position welding of critical structural applications, such as TKY joints in offshore construction, pipe structures, bridges and storage tanks.
