Carbon Steel Steel Flux Cored Arc Welding E71T-1
E71T-1 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 70,000 psi 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.
