Cast iron welding wire rod electrode without any nickle
Cast iron welding wire rod electrode without any nickle
1. Characteristics
CI-600 is a graphite type coated electrode, depositing weld metal consisting of pure iron. It is designed for welding of cast iron when machining of the
deposit is not required. Hardness of the bonded area will be higher than that with nickel type electrode.
2. Applications
Repairing of various kinds of cast iron products.
3. Notes on usage
(1) Clean base metal before welding.
(2) If there is a possibility that cracking spreads, make the stopholes at both ends of repairing part.
(3) Keep bead length less than 50mm to disperse welding heat. Adopt back step, stepping stone or symmetry method by turns.
(4) Hot peen in every pass.
(5) The preheat temperatures vary in accordance with kind, shape and size of base metal. Preheating at 200~350℃ is appropriate to prevent cracking.
Slow cooling is recommended after welding.
