    Experimental Investigation of Effect of Laser Process Parameters and Heat Input on Hardened Bead Geometry and Power Density of ASTM Grade 3 Pure Titanium using CW Laser Beam

    By Duradundi Sawant Badkar

    Abstract: This research paper presents the experimental study of laser process parameters and heat input on hardened bead profile of ASTM Grade 3 commercially pure titanium sheet of 1.5 mm thickness using 2kW CW Nd: YAG laser. The selected two laser process parameters are: (1). Low laser process parameter (LLPP): Laser Power (LP): 600 Watts, Scanning speed (SS): 2000 mm/min, Focused position (FP): -10 mm with heat Input (HI): 180 J/cm …
