- Electron Beam Welding (EBW)


Electron Beam Welding provides great strength and consistent weld size of thick to thin materials. Many difficult to weld metals can be welded using the EB welding process. EB welding is able to achieve deep penetration while still having narrow welds.

Electron Beam Welding provides consistent weld size and high joint strength. Welding of thick to thin material and dissimilar metals is easily accomplished. EB welding permits joining of reactive and refractive materials. Materials considered difficult to weld by conventional processes may often be welded using the EB welding process. EB welding is able to achieve deep penetration, narrow welds providing low distortion. The narrow heat affected zone (HAZ) allows joining parts in the finished or near finished shape. Heat sensitive parts benefit from the low overall heat input.

 ATCo's specialty is working with the customer to develop the best method for joining of difficult to weld and/or complex hardware. ATCo utilizes high voltage style electron beam welders which permit a narrower beam profile and lower distortion than low voltage style machines. ATCo is vertically integrated; self sufficient in developing tooling, maintaining equipment, determining processing and handling final inspection.

ATCo's wide range of equipment, with multi-part positioners, allows high volume, cost-effective welding.

  • Various chamber extensions permit welding of very long parts, over 200 inches.
  • Large diameter parts, can be handled in two different welders.
  • One of the most experienced EB welding facilities in the U.S.
  • Over 40 years of experience.
