Parameters optimization of Ti6Al4V alloy welding by pulsed Nd:YAG laser
Original language description
The butt welds of thin Ti6Al4V alloy sheets using a pulsed Nd:YAG laser were investigated to determine the optimal value of peak power and pulse length for creating sound welds. The width of the weld face and the depth of penetration were found to be proportional to increasing peak power and decreasing pulse length. The weld surfaces were measured using a contact profilometer. The influence of laser pulse overlap on the thermal cycle in representative point and cross-section planes was demonstrated by a numerical model. Repeated melting and heating above the transformation temperature by previous and following pulses probably caused the occurrence of a mixed microstructure of α´martensite and massive α in the fusion zone and near the heat-affected zone. Nanohardness tests on the transverse cross-sections showed that the fusion zone was approximately 50% harder than the base material.
