What is 9-Abaqus - Ti-6Al-4V TIG Weld Analysis Using FEM Simulation and Experimental Characterization about?

This research paper analyzes the TIG welding of Ti–6Al–4V alloy using FEM simulation and experimental methods to optimize welding current for improved mechanical properties. A 3D transient FEM model was developed to predict heat input, weld bead geometry, and residual stress distribution, with validation against experimental data showing a suitable welding current range of 130–170 A. Results indicated that lower welding currents lead to higher tensile strength and hardness due to reduced heat input and a fi
