We offer Electron Beam Welding on a contract basis. This is a high energy density
process which can make welds with very low distortion. The welding is done in a vacuum, so
external contamination is not introduced. Welds can be made in metals that are not
weldable by other methods.
Key Benefits
- Clean - all welds done under high vacuum
- Deep, narrow welds possible - depth = 10-40 times width
- Very low distortion
- Can eliminate secondary operations
- No filler metal or bevels required
- High welding speeds - 30/100 ipm
- Normally inaccessible joints can be welded

- Carbon and Stainless Steels
- Aluminum Alloys
- Nickel-Based Alloys
- Titanium and Zirconium
- Refractory Metals:
