Abstract
Welding wires and methods for welding metal work pieces using the welding wires are provided. The welding wires are composite materials comprising a metal alloy and high temperature nanoparticles dispersed in the metal alloy.
Claims20
A method of welding metal work pieces comprising metal alloys, the method comprising:
- melting at least a portion of the metal alloy of the work pieces in the proximity of an interface between the work pieces;
- melting at least a portion of a welding wire in the proximity of the interface, the welding wire comprising a metal alloy and a plurality of high temperature ceramic or high temperature intermetallic nanoparticles dispersed in the metal alloy, whereby a molten weld pool comprising molten metal alloy from the work pieces and molten metal alloy from the welding wire is formed;
- and
- allowing the molten weld pool to solidify, thereby forming a welded joint at the interface.
A welding wire comprising a composite material comprising a metal alloy and a plurality of high temperature ceramic or high temperature intermetallic nanoparticles dispersed in the metal alloy, wherein the composite material is in an elongated form characterized by a length and a diameter, both of which are sized to render the elongated form suitable for use as a welding wire.
