Select ECF2

Low Alloy / Submerged Arc / Flux Shielded

Resources

Features

  • Intended for single and multiple pass welding of high strength low alloy (HSLA) and micro-alloyed steels where a combination of 90 ksi ultimate strength and good notch toughness are required.
  • Higher deposition rates than solid wire when run at the same current level
  • Exhibits a broader and shallower bead profile than when using solid wire, reducing the tendency for burn through
  • Capable of running directly over root passes with proper procedure – eliminating requirement for a hot pass
  • Easy slag removal – reduces post weld cleanup time
  • Arcflux BF-10MW is the recommended flux, although other fluxes with high basicity can be used in place of this.
