Select EM13KS

Carbon Steel / Submerged Arc / Flux Shielded

Resources

Features

  • Intended for single and multiple pass welding of carbon and certain low alloy steels, and can be substituted anywhere that a solid EM13K electrode is used.
  • Produces a weld deposit chemistry similar to EM13K solid wire electrodes.
  • 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 active and neutral fluxes can be used in place of this.
