Chosun CI-500 Cast Iron Welding Rod
Repairing and filling up of cavities of various kinds of cast iron products such as cylinder covers, motor beds, casings and gears. Repairing of meehanite cast iron, alloy cast iron and malleable cast iron.
| Classification | AWS A5.15 ENi-Cl |
| Applications | Repairing and filling up of cavities of various kinds of cast iron products such as cylinder covers, motor beds, casings and gears. Repairing of meehanite cast iron, alloy cast iron and malleable cast iron. |
| Characteristics | CI-500 is a graphite type coated electrode, depositing weld metal consisting of almost nickel. Hardening of the weld metal and fusion zone in cast iron is smallest and machining of the welds is comparatively easy. Therefore, it is suitable for welding alloy cast iron of poor weldability, malleable cast iron and hydraulically pressured parts as well as common cast iron. |
| (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) It is not necessary preheating and postheating in general but satisfactory results can be obtained by preheating at 100~200℃ in accordance with kind, shape and size of base metal. | |
