Why is electron beam welding used in the aerospace industry ?
Electron beam welding is used in the aerospace industry to handle difficult and exotic materials and dissimilar metal combinations. Electron Beam welding is an exact process due to the narrow beam, so it does well in avoiding damaging nearby electronics and minimizing the heat input into an assembly. This allows the weld to maintain about 97% of the strength of the base materials. Electron Beam welding is also a very repeatable process which maintains the consistency and quality of the welds over hundreds and thousands of parts in a batch.
