Electron Beam Welding Vs Laser Welding

Electron beam welding ebw and laser beam welding lbw and are both fusion welding techniques that use a high energy density beam to melt the joint of two components.

Electron beam welding vs laser welding.

Both methods have fast cycle times and produce high weld quality. The generation of a high power electron beam in a vacuum environment accelerating this stream of electrons via high voltage applied between the cathode and anode and then electromagnetically focusing that total power to a very small spot on the piece to be welded. However both eb welding and laser welding processes are versatile flexible and if applied correctly each can make reliable and enduring welds. They are similar and can be used side by side in some circumstances but they are not identical.

Electron beam will be the primary choice when the completed assembly must be sealed with internal components under vacuum when weld penetrations exceed 1 2 when the material is challenging to initiate laser coupling or. Lower cost to setup than ebw no vacuum or enclosures required can weld virtually any size component not limited by chambers short cycle times. Pros of laser beam welding. Electron beam and laser welding are excellent means to fuse metals.

Electron beam welding vs laser welding. On the electron beam welding vs laser beam welding debate it is clear there is no clear cut front runner between these two welding methods. The first high power density welding systems were electron beam. Laser processing is required either when the size of the final assembly is too large for an eb welding chamber some component in an assembly is incompatible with vacuum processing such as a liquid or gas or when the weld is inaccessible to an electron beam source.
