Application of Nanostructured Powders to Control Characteristics of Electrode Metal Transfer and the Process of Weld Structurization

Abstract:

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 Al₂O₃ is the most consistent process and application of nanostructured powders enables controlling the structure and the morphology of a surfaced metal.
