Description :

A semi-basic type electrode depositing air hardening type of weld metal which has excellent resistance to severe abrasion and moderate impact. The electrode is very easy to use and gives smooth weld surface. The deposit is non-machineable and can be shaped by grinding.

Applications :

  • Crusher jaws : Cane cutting knives
  • Crusher hammers : Shear blades
  • Heavy earth moving equipment : Paper cutting knives
  • Conveyor parts : Punches, dies

Recommendations :

  • Keep electrodes dry. In case of moisture pick-up re-dry the electrodes at 150oC for one hour.
  • Use short arc, low current and minimum weaving of electrodes.
  • For thick deposits on austenitic manganese steel components, GM- Mn electrode should be used for buffer layers.
