BOR-C is a basic coated electrode producing an air hardening weld metal which has excellent resistance to abrasion or heavy impact or both together. The welds are non-machinable and are ideally suited for applications involving severe abrasion and impact. Typical applications include cane cutting knives, crusher hammers, jaws, rollers, rock drills, tractor grousers, etc.
1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
2. Use short arc and stringer bead.
