Fiber Laser Marking, Colour Intensity, Marked WidthAbstract
The paper deals with the analysis of marking quality on Ti6Al4V by using thermal energy of laser beam. The variation of process variables such as laser irradiation, pulse rate, scan rate, duty cycle and transverse feed resulted in the generation of colours on the surface which have a considerable marking contrast value. The intensity analysis conducted on line marking and surface marking reveals the fact that variables like laser irradiation, transverse feed, and scan rate plays a significant role in the change of colours when other process variables are held constant. Experimental studies revealed that the highest mark intensity obtained was 0.70 (pinkish colour) where lowest value obtained was 0.10 (purple colour whereas the standard maximum and minimum mark intensity were 1 (white) and 0 (black).
