Electron Beam Welding SERVICES
EBTEC's array of Electron Beam Welding machines allows us to handle everything from development and small runs of prototypes to large-volume production of our clients' components, with the precision and speed expected of an industry leader.
Our facilities house 13 Electron Beam welders, ranging from low-voltage machines producing 2.5kw to high voltage machines producing 25kw. Our machines' chamber capacity runs from as small as 1 cubic foot to the largest Electron Beam Welder on the East Coast, at 1,320 cubic feet.
Additionally, our fully automated shuttle systems allow us to process high-volume production quickly. All of EBTEC's Electron Beam Welding machines are either full- or semiautomatic-CNC control, ensuring the highest amount of precision in production, and our facility is both ISO and NADCAP certified.
About Electron Beam Welding
Electron Beam (EB) Welding is used for joining ferrous metals, light metals, precious metals, and other alloys to themselves or each other. Our Electron Beam Welding services offer you and your components the following advantages:
- Versatility from .002" depth to 3.00" depth of penetration
- Multi-axis EB control
- High ratio of depth-to-width
- Maximum penetration with minimal distortion
- Exceptional weld strength
- Ability to weld components up to 10' in diameter
- High precision and repeatability with virtually 0% scrap

The Electron Beam Machine Process
An Electron Beam Welding system is composed of an electron beam gun, a power supply, control system, motion equipment, and vacuum-welding chamber. Fusion of base metals eliminates the need for filler metals. The vacuum requirement for operation of the electron beam equipment eliminates the need for shielding gases and fluxes. The electron beam gun has a tungsten filament, which is heated, freeing electrons. The electrons are accelerated from the source with high-voltage potential between a cathode and anode. The stream of electrons then passes through a hole in the anode. The beam is directed by magnetic forces of focusing and deflecting coils. This beam is directed out of the gun column and strikes the workpiece.
The potential energy of the electrons is transferred to heat upon impact of the workpiece and cuts a perfect hole at the weld joint. Molten metal fills in behind the beam, creating a deep, finished weld. The electron beam stream and workpiece are manipulated by means of precise, computer-driven controls, within a vacuum welding chamber, therefore eliminating oxidation or contamination.
