Laser beam welding in a vacuum for optimized steel welding
Laser beam welding in a vacuum (LaVa-welding) is a new and highly innovative process. Compared to conventional laser beam welding, it is characterized by an increase in process stability [1] with a simultaneous increase in quality (comparable to electron beam welds [2]) and weld penetration depth [3]. Conversely, this also means that a required penetration depth can be achieved with significantly reduced energy input by up to 60 % [4], Figure 1.
