Low Alloy / Submerged Arc / Flux Shielded


  • Intended for single and multiple pass welding, primarily of T1 steel. Can also be used to weld other alloys where a strength level of 110 ksi is required.
  • Normally used in the as-welded condition.
  • 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 clean up time
  • Arcflux BF-10MW is the recommended flux, although other neutral fluxes with high basicity can be used as well.
