Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The method of claim 1 , wherein placing the first portion of the metal article adjacent to the second portion of the metal article comprises clamping the first portion and the second portion together via a clamp. 3. The method of claim 1 , wherein additively manufacturing the first portion of the metal article comprises forming a channel in the first portion of the article, and wherein the method further comprises placing the resistive heating material in the channel. 4. The method of claim 1 , further comprising adding filler material to the channel. 5. The method of claim 1 , further comprising additively manufacturing the resistive heating material by depositing a layer of the resistive heating material on the first portion of the metal article. 6. The method of claim 1 , wherein placing the first portion of the metal article adjacent to the second portion of the metal article comprises connecting the first portion and the second portion together via one or more of complementary connectors and threads. 7. The method of claim 1 , wherein directing electric current through the resistive heating material to produce heat via the resistive heating material comprises inductively directing electric through the resistive heating material.
