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
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 …

Overlapped Multipass Laser Transformation Hardening of Ti-6Al-4V Titanium Alloy Using Continuous Wave Rectangular Beam
Abstract: Overlapped multitrack laser transformation hardening (OMLTH) of Ti-6Al-4V titanium alloy of Grade 5 of 2 mm thickness sheet has been carried out using 2 kW Nd:YAG laser source with a CW rectangular beam of size 1×14 mm2. The present research article intended to provide a profound understanding of the multipass laser hardening process of TI-6Al-4V titanium alloy, and to investigate the effect of rectangular laser beam process parameters i.e., the …
