Non-Machinable weld for applications involving severe abrasion
LoTherme-623F is a basic coated electrode producing an air hardening weld metal which has excellent resistance to abrasion. The welds are non-machinable and are ideally suited for applications involving severe abrasion.
Typical applications include cane cutting knives, crusher hammers, jaws, rollers, rock drills, tractor grousers, etc
53 – 56 HRC
Ensure that the electrodes are perfectly dry before use. In case of moisture pick-up, re-dry the electrodes at 250-300°C for one hour before use. Clean the weld area free of any surface contamination.Hold a short arc length and weld with stringer beads.
