Abstract
Application of high-production electrodes in welding-up of casting defects and repair of stands is still relevant up to present moment. Efficiency of surfacing process can be increased by using exothermal mixtures in coating. The work studies the possibility of optimizing fusion of electrode coating with iron powder containing scale of rolling industry and aluminum powder. Statistical model was proposed allowing optimizing content of exothermal mixture in coating for minimizing loss of electrode metal. 6 Ref., 6 Figures.
