Description: E71T-8-H8  is a self-shielded, carbon steel, flux cored electrode. It is intended for the welding without a shielding gas of carbon and certain low alloy steels where excellent low temperature toughness is required. A fast freezing slag facilitates welding in all positions. It has a smooth globular transfer, excellent bead shape and easily removed slag. E71T-8-H8 is designed for structural applications such as bridge fabrication, ship and barge construction, as well as other general fabrication. Classification & Approvals: E71T-8-H8 per AWS A5.20, ASME SFA 5.20 E71T8-A2-CS3-H8 per AWS A5.36, ASME SFA 5.36 AWS D1.8 Seismic, CWB E491T-8-H8, ABS 3YSA, DNV IIIYMS Advantages: Operates on straight polarity (DCEN) with no external shielding gas. Fast freezing slag facilitates excellent weldability in all positions. Exhibits a smooth globular transfer, minimal spatter and easily removed slag.
