In which of the following welding techniques in vacuum environment req...
-Electron-beam welding is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.

-It is performed in a vacuum without shielding gas.
-Electron beam welding is used to melt and join base materials. Because the welding is characterized by a small spot with minimal heat effects, couplings with no gaps are ideal.

Electron Beam Welding
Electron beam welding is a technique that involves using a high-velocity electron beam in a vacuum environment to join metals together. This process is commonly used in industries such as aerospace, automotive, and electronics due to its ability to provide precise and high-quality welds.
Why Vacuum Environment is Required
- In electron beam welding, a vacuum environment is necessary to prevent the electrons from colliding with air molecules, which can scatter the beam and reduce its effectiveness.
- The absence of air also helps to minimize oxidation and contamination of the weld, resulting in stronger and more reliable joints.
Advantages of Electron Beam Welding
- High precision: Electron beam welding can provide highly precise welds with minimal distortion, making it ideal for applications where accuracy is crucial.
- Deep penetration: The high-energy electron beam can penetrate deep into the material, allowing for the welding of thick sections in a single pass.
- High welding speed: Electron beam welding is a fast process, making it efficient for large-scale production.
Conclusion
In conclusion, electron beam welding is a powerful technique that requires a vacuum environment to operate effectively. By harnessing the energy of high-velocity electrons, this welding method offers numerous advantages for joining metal components in various industries.
