Deskripsi
Karakteristik:
LKE-NiFe-CI is a covered electrode with graphite type coating and Fe-Ni alloy core rod. The weld metal provides low expansion coefficient, less hardening and good machining property. It is suitable for ductile cast iron, malleable cast iron and gray cast iron.
Aplikasi:
For repairing of mining equipment, engine blocks, marine equipment and other heavy manufacturing equipment.
Catatan tentang Penggunaan:
1.Hot peening prevent the shrinkage stress.
2.Clean up to prevent contamination.
3.Preheat the base metal at 300℃, PWHT at 500-600 °C.
4. Gunakan arus listrik yang kecil dan jaga agar busurnya sependek mungkin
