E71T-11 .035 Flux Core 2 lb Spool Welding Wire MIG Blue Demon
E71T-11 is a self-shielding flux cored wire used for welding carbon steels. This product does not require a shielding gas and can be used in limited multi-pass welding operations. The bead appearance is not equal to a gasshielded product, but the benefits of not having to use gas makes this product popular. E71T-11 operates on straight polarity only (DCEN). Typical Applications • Butt, lap and fillet welds on steel 16 gauge through 1/2″ • Assembly and maintenance welding • Machine parts • Tanks • Prefab construction • Light structurals • Short assembly welds • Railroad car repairs AWS Specification AWS A5.20/A5.20M:2005 AWS Classification E71T-11 Welding Current DCEN (Electrode Negative, Straight Polarity) Typical Wire Chemistry C 0.30 Mn 1.75 Si 0.60 S 0.03 P 0.03 Cr 0.20 Ni 0.50 Mo 0.30 V 0.08 AI 1.8 Cu 0.35 Typical Mechanical Properties (As Welded) Yield Strength, ksi 58 Tensile Strength, ksi 70 – 95 Elongation%, min 20 Welding Positions F,H,V-down,OH Available Diameters and suggested Operating Range in Amps .030″ 40 – 100 035″ 100 – 130 .045″ 140 – 180 1/16″ 175 – 300
