The advantage of Electron Beam Welding compared to Laser Welding is superior quality of welds with no oxidization. The advantage of laser beam welding vs electron beam welding is that no vacuum is required. Therefore, this eliminates the need for a vacuum chamber a pumping system and the time necessary to evacuate the chamber. Faster cycle time translates to lower cost.
Applications for electron beam welding include: aerospace, automotive, semi-conductor, electronic components and jewelry. The process has proved very reliable and cost-effective in high volume production due to the advent of small vacuum chamber machines.
An advantage of electron beam welding is the ability to weld in areas not possible by conventional means since an electron beam can be projected into previously inaccessible locations.
