Electron beam welding fuses metals by applying a high-energy electron beam to the joint, where the beam is transferred into heat, which forms the weld.
The process is typically carried out in a vacuum in order to achieve pure welds with high depth-to-width ratios. However, special orifices designed to provide varying levels of vacuum are sometimes used.
Advantages of Electron Beam Welding
Disadvantages of Electron Beam Welding
- High equipment and weld preparation costs
- Possible cracking due to rapid solidification
- Welding in vacuum may cause time delay
Applications of Electron Beam Welding
Electron-beam welding is the preferred method for manufacturing high-value welds in applications in which defects cannot be tolerated. The nuclear energy and aerospace industries, as well as the Department of Energy, rely on electron-beam welding to join critical components; welds created through the electron-beam process are of high reliability, consistency and reproducibility.
