What is Electron Beam Welding?

 Our seven electron beam welding machines are equipped with vacuum chambers up to 36″ x 36″ x 52″. Generated by an “electron gun”, the stream of electrons travels at up to 60% of the speed of light. Its kinetic energy is converted into extremely high temperature on impact with the workpiece. Because the power density (watts per square inch) is so high, difficult welds can be performed. For example, a two inch thick stainless steel part can be welded with only 6 kw. of beam power.


With low total energy input to the workpiece, distortion and deformation are reduced to an absolute minimum. The fusion zone is deep but very narrow as compared with other welding processes – ratios as high as 20:1 are obtained. Both beam power and spot size can be precisely controlled, for welds ranging from .003 to 1.25 inches deep.

The high purity of the electron beam process permits welding of reactive materials that are very sensitive to contamination. Electrons have no chemical or material properties, and because the welding is performed in a hard vacuum, the fusion zone is kept contaminant free.

Please call us for detailed information and technical recommendation on your specific application. From one-of-a-kind prototypes to full production, Electron Beam Fusion can insure the highest level of competitive, quality welding.
