ADVANTAGES OF USING (OFW) GAS HARDFACING METHOD

  • Low temperature deposition with minimal change to base metal
  • No special equipment required therefore little investment cost
  • Optimal wear properties in first layer therefore savings in filler material cost
  • OFW weld deposits provide greater wear resistance then electric arc overlays.
