Abstract

The possibility of using the heredity effect under arc deposition and its impact on the structure and properties of multilayer tool steel-type metal was investigated. Deposition was performed using flux-cored wires with varying preparation methods and compositions of charge materials, calculated such to achieve the same chemical composition in the deposited metal. The charge materials in the experimental flux-cored wires included granulated metal powder PG-R6M5 in three particle size ranges: 50–100; 200–250 and 50–300 μm. In the reference flux-cored wire, ferroalloy powders with a particle size of 50–300 μm were used. The replacing ferroalloys with chemically purer and physi­cally more homoge­neous granulated metal powders improves the welding-technological properties of flux-cored wires, stabilizes the deposition process, and enhances the structure of the deposited metal. The best results were achieved using metal powder with a particle size of 50–100 μm.
