Abstract

The increasing availability of highest power lasers broadens the economic use of deep penetration laser welding by increasing maximum welding depth and by increasing welding speed. The problems encountered in those two areas of interest differ significantly. Whereas the maximum welding depth is strongly affected by the absorption mechanism1,2, the maximum welding speed is limited by fluid dynamic phenomena . Theoretical modelling allows to seperately investigate the different processes.
