Description

technical field [0001] The invention belongs to the technical field of welding materials, and in particular relates to a nickel-based alloy submerged arc welding sintered flux and a preparation method and application thereof. Background technique [0002] With the rapid development of my country's economy, new energy development has gradually become a hot spot in my country's energy development. [0003] In the development process of new energy, more and more equipment manufacturing uses nickel-based alloy welding. In order to improve welding efficiency, nickel-based alloy submerged arc welding is gradually widely used. Domestic nickel-based alloy submerged arc welding materials mainly rely on Imported, for the welding of nickel-based alloys, the domestic related research started relatively late, and some experience has been accumulated at present, but it still needs to be further improved and improved. [0004] So far, there are not many patents related to nickel-based sub...
