| Abstract: | The paper introduces the key producdon procedures for pure nickel powder: vacuum melting, nitrogen shielding, and fog- solidification. The powder has many advantages: high content of globular grains, pure composition etc. Thereby, the nickel powder is suitable to produce flux - cored welding wires. |
