The laser–powder interaction process (LPIP) and molten pool dynamic behaviors (MPDB) during laser directed energy deposition (LDED) have significant effect on the forming quality of parts. In this paper, a LDED numerical model is established for controlling LPIP MPDB by beam defocusing (LBD). Based calculated results from model, influence LBD investigated. With amount increasing, power density (LBPD) its attenuation amplitude are reduced. uniformity distribution (LBPDD) improved average...
The energy distribution in molten pool is highly related to the quality of weld formation aluminum alloy welding. forming defects are often improved by adjusting dynamic behaviors affected distribution. Therefore, characteristics during welding with oscillating laser “∞” shaped path explored this paper. pore found be greatly reduced welds from compared those non-oscillating corresponding obtained and analyzed. process under conditions different discussed. results good agreement experimental...
