Whether your requirements call for the development of a prototype part or fabrication services for large volume production, Sciaky has the right solution to meet your needs. Best of all, Sciaky's welding services are competitively priced and offer tremendous advantages over smaller job shops in terms of equipment and expertise. Give us a call. There's simply no other welding services provider on the planet like Sciaky.

Why EB?

EB is an excellent choice for applications containing refractory alloys and dissimilar materials. Advantages of electron beam welding include a high power density with very low overall heat input and, therefore, minimum distortion. Electron beam welded parts require a minimum of post weld machining and heat treatment, and, unlike other fusion welding processes, electron beam requires no shielding gases. The weld quality is exceptional and the process is extremely efficient (typically 95%), carefully controlled and fully automated.

Our Electron Beam Welding services offer you the following advantages:

• Versatility to weld thin foils to thick sections (greater than 2.5" depth
of penetration)
• Multi-axis EB control
• High ratio of depth-to-width
• Maximum penetration with minimal distortion
• Exceptional weld strength
• Inert atmosphere (vacuum)
• High precision and repeatability with virtually 0% scrap

Sciaky has been at the forefront of EB welding technology for decades and has used this time-tested technology to meet stringent military specifications on items such as airframes, landing gear, jet engines, guided missiles and vehicle parts.

EB Direct Manufacturing

Sciaky's exclusive Direct Manufacturing (DM) solution, which utilizes our state-of-the-art EB systems, is the only commercially-available, large-scale, fully-programmable means of achieving near-net shape parts. This unique technology can be provided as a service to produce functional prototypes and production parts at a fraction of the cost of traditional manufacturing methods. The process starts with a 3D model from a CAD program and utilizes Sciaky's fully-articulated, moving electron beam gun to deposit metal, layer by layer, until the part is ready for finish machining. Depending on the part being manufactured, deposition rates can range from 15 to 40 pounds of metal per hour.

Example of assemblies/components/parts welded using Sciaky's EB technology

• Superconducting Cavities for High Energy Physics
• Aircraft Engine Cases & Assemblies
• Military Aircraft Components & Structures
• Rock-bit Assemblies & Tank Tubes for Petroleum/Mining Diaphragm Assemblies for Power Generation
• Transmission Gears for Automotive & Truck/Off-Highway
