Influence of Nanostructured Powder Modifiers on the Structure of a Welding Bead

Abstract:

Addition of nanopowders of tungsten and aluminum oxyhydroxide to the weld pool has shown positive effect on the structure of metal during arc gas welding with a consumable electrode. It has been shown that introducing the powders decreases dendrite size and leads to the formation of a more equilibrium micrоstructure.
