Description

technical field [0001] The invention relates to the technical field of welding materials for metal welding, in particular to a method for calculating the addition amount of flux-cored wire alloy powder raw materials. Background technique [0002] With the development and progress of steel materials, various new steel products are used in various industries. Welding consumables for welding iron and steel materials need to be selected according to the composition design characteristics and strength grades of steel products. Flux-cored welding wire has the advantages of short development period, good welding process performance, and beautiful weld shape, so it has a wide range of application fields in welding. Flux-cored welding wire is composed of thin metal strip and evenly distributed welding wire powder in the strip. After the welding wire is welded, the metal thin strip and welding wire powder are melted to form weld metal, and the mechanical properties, corrosion perform...
