Use of Beam Deflection to Control an Electron Beam Wire Deposition Process

NASA Langley Research Center researchers have a strong technology foundation in the use of electron-beam (e-beam) deposition for freeform fabrication of complex shaped metal parts. While e-beam wire deposition is of interest for rapid prototyping of metal parts, cost-effective near-net shape manufacturing, and potential use in space, it is also of intense interest for industrial welding and fabrication in a range of applications, from small components to large aerospace structures. Through significant advancements in techniques to improve control of the process, NASA greatly expands upon the capabilities of the e-beam fabrication and welding process.
