Abstract
An article comprising additively manufactured metal portions is described. The article comprises a first additively manufactured metal portion, and a second additively manufactured metal portion coupled to the first additively manufactured metal portion at a welded joint. The article further comprises a resistive heating material disposed within an interior of the welded joint, the resistive heating material comprising a different material than the first additively manufactured metal portion and the second additively manufactured metal portion.
Claims7
A method of forming a metal article, the method comprising:
- additively manufacturing a first portion of the metal article;
- additively manufacturing a second portion of the metal article;
- placing the first portion of the metal article adjacent to the second portion of the metal article to locate a resistive heating material within an interface between the first portion of the metal article and the second portion of the metal article, the resistive heating material comprising a different material than the first portion of the metal article and the second portion of the metal article;
- directing electric current through the resistive heating material to produce heat via the resistive heating material;
- and
- welding the first portion of the metal article and the second portion of the metal article together via the heat produced via the resistive heating material.
