Electron Beam Welding Vs Laser Welding

However both eb welding and laser welding processes are versatile flexible and if applied correctly each can make reliable and enduring welds.

Electron beam welding vs laser welding.

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. Eb welding can achieve high production speeds with the right part and the right fixturing and laser beams can make beautiful pure welds with the right materials and setup. The first high power density welding systems were electron beam. Both methods have fast cycle times and produce high weld quality.

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. 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. Each method has its pros and cons. 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.

Electron beam and laser welding are excellent means to fuse metals. They are similar and can be used side by side in some circumstances but they are not identical. But in some cases even that isn t true. Lower cost to setup than ebw no vacuum or enclosures required can weld virtually any size component not limited by chambers short cycle times.
