Application of nanostructured powders to control characteristics of electrode metal transfer and the process of weld structurization

摘要

The paper considers the influence of nanostructured powder-modifiers on transfer of the electrode metal drop and the microstructure of a surfaced metal in consumable electrode welding in argon shielding. It is found, that welding with the nanopowder Al_2O_3 is the most consistent process and application of nanostructured powders enables controlling the structure and the morphology of a surfaced metal.
