▎Welding Instruction

  • Formation of key-hole during welding is very important in order to supply slag onto reverse side bead.
  • The melting rate of flux cored wire is higher than that of solid wire due to flux addition. The speed of wire feeding must be higher.

  • Only for root pass in single-side welding, not for cover pass.

▎Application

Suitable for welding 18%Cr-8%Ni-Nb steel (AISI 347) and18%Cr-8%Ni-Ti steel (AISI 321).
