Laser beam welding (LBW) and electron beam welding (EBW) are well-established methods for industrial application. Although being in competition to one another every so often, their process-specific properties allow the processes to cover their own application fields. In the field of beam welding methods there have, for years, been constant attempts to change and extend the possibilities for application. Among those are the further development of the equipment technology and also the improvement of the mathematical models for process simulation and prediction of welding results. Laser beam welding in vacuum (LBW-V / LaVa) is a new process variation which may allow to open up new application fields. To the users of beam welding technology, this process variation may provide an alternative to the LBW- or EBW methods/equipment which have been applied so far. The process variation offers, moreover, important data for process modeling since it is possible to examine the beam-matter-interactions during laser beam welding without the interaction with the atmosphere. This paper presents a comparison between laser beam welding in vacuum and electron beam welding in vacuum. |
