A survey on future research about electron beam welding for aerospace applications

Electron beam welding plays an important role in the aerospace industry where components like sensors, gears, actuators and air frames used in aircraft and rocket engines were welded using this technique. Welding is normally performed in a vacuum to avoid the scatter of electron due to the presence of gas molecules in the atmosphere and hence electron beam welding process provides the greater results. But still joining of dissimilar metals is challenging. This paper represents review of process, generation and distribution of heat source various input parameters, materials, microstructure, mechanical strength and the possibilities of joining dissimilar metals using electron beam welding.
