Select ECB2-S

Low Alloy / Submerged Arc / Flux Shielded


Features

  • Intended for single and multiple pass welding of base metal with similar Cr-Mo composition.
  • Higher deposition rates than solid wire 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
  • Typical applications include welding of 1¼ Cr – ½ Mo pipe and plate like ASTM A335-11 pipe and A387 Grade 11 plate, All welds need to be post weld heat treated.
  • Arcflux BF-10MW is the recommended flux, although other neutral fluxes with high basicity can be used as well.
