摘要:
The figure-8 oscillating laser can improve the quality of cladding and has great value for industrial applications, but its molten pool heat transfer and flow behavior are poorly known and seldom reported. For this reason, an in-depth understanding of the heat flow characteristics of the molten pool in this special laser mode is of great significance to the molding law of microstructure as well as the regulation work. In this work, a finite element model of laser cladding with multi-physical fields is established to investigate the effects and laws of different oscillation frequencies and ampl...
