Development of nickel base alloy covered electrode enicrmo-3 for all position welding

Nickel base alloy covered electrode ENiCrMo-3 type Ni625 for all position welding was developed by reasonably adjusting ratio of carbonate, fluoride and oxide in the electrode and controlling alloying element content of deposited metal. The results showed that all performances of the developed electrode can meet the requirement and it exhibits good technological performances in all position welding, excellent intergranular corrosion resistance and hot cracking susceptibility.
