Electron Beam Welding (EBW) is a fusion process in which a beam of high-velocity electrons is applied to the materials being joined. As the electrons strike the work surface, their energy is converted into heat, instantly vaporizing the metal, creating a keyhole. 

The heat penetrates deeply, making it possible to weld thicknesses over 2 inches and still capable of welding foils, which is typically not possible with most other welding processes. Because the electron beam is tightly focused, the total heat input is magnitudes lower than most processes including Laser Welding. SWS-Trimac performs Electron Beam Welding at vacuum levels greater than 1 micron to prevent dispersion of the electron beam. As a result, the effect of welding on the surrounding material is minimal and the heat-affected zone is small, distortion is slight, and the work piece cools rapidly. 

The electron beam can be finely focused to .008” beam spot sizes offering very deep yet narrow signatures with depth to width ratios of 20:1, conversely, the beam can be defocused to create a larger beam spot resulting in wider weld signatures for applications that demand precise weld widths at specified depths. The beam may also be oscillated or stirred to create an array of possibilities depending weld settings, tailored to your application needs.
