Title of Paper:Experimental and simulation study on the microstructure of TA15 titanium alloy laser beam welded joints

Journal:OPTICS AND LASER TECHNOLOGY

Key Words:TA15 titanium alloy Laser beam welding Microstructure Simulation

Abstract:Laser beam welding technique offers obvious advantages over other fusion welding processes in terms of joining titanium alloy. The microstructure of welded seam and heat affected zone resulted from diverse welding speeds and laser powers were investigated after simulating welding heat treatment. The analysis of the thermal transport properties successfully explained the morphology. Optimal process parameters were obtained. The simulation results were consistent with the corresponding experimental observations. (C) 2017 Published by Elsevier Ltd.
