E71T-1/1M is an all-position, flux cored welding wire, which is intended for single and multiple pass welding of low-alloy and carbon steel where a minimum 70 ksi tensile strength and good notch toughness is required. It is an excellent general purpose welding wire. This wire has very low fume, stable arc, good slag removal and excellent mechanical properties. Typical Applications • Buff and fillet welding of hulls and storage tanks. • Structural steel • Farm machinery • Construction equipment • General carbon steel fabrication AWS Specification AWS A5.20/A5.20M:2005 AWS Classification E71T-1 /1M Welding Current DCEP (Electrode Positive, Reverse Polarity) Typical Wire Chemistry C 0.12 Mn 1.75 Si 0.90 S 0.03 P 0.03 Cr 0.20 Ni 0.50 Mo 0.30 V 0.08 Cu 0.35 Typical Mechanical Properties Yield Strength, ksi 58 Tensile Strength, ksi 70 - 95 Elongation%, min 22 Minimum Charpy V-Notch Impact Energy 20ft•lbf@0ºF Welding Positions All positions Available Diameters and suggested Operating Range in Amps .035" 100 - 250 .045" 200 - 300 .052" 100 - 330 1/16" 150 - 400
