Electron-Beam Welding
We, Rasa Industries, have been achieving remarkable experiences and results in many industrial fields in past decades.
Our large-sized equipment takes advantage of correspondence with many types of business from small-sized works to medium and big sized ones as well.
Recently, we have accomplished great results of typical works in semiconductor field, flat panel field, aerospace field, energy field and etc.
Please take a look our unique process of E-Beam Welding service and feel free to contact us.
■ Strong-points of E-Beam Welding
- The beam will be stable since the control system is performed electronically, so it makes excellent reproducibility at high level of quality.
- Deep penetration welding is possible by narrow width of bead since the electron beam has a high energy density,
- The amount of heat input and the deformation during welding is comparably small, and the range of heat affected zone is also narrow.
- It is available for wide range of welding such as High melting point (W, Mo, Nb) materials, high thermal conductivity (Ag, Cu, Al) materials and etc.
- It is also able to weld nonferrous metals (Al, Cu, Ti).
- It allows to weld between two dissimilar materials (Cu-SUS, Cu-Kovar).
- There is no contamination or oxidation by gas because of its welding in high vacuum.
- You could have a choice between a specific and a general joint shape or both.
