Numerical Simulation of Temperature Fields by Welding of Ti-Al Alloys Applying Volumetric Heat Source

Article Preview

Abstract:

Transient temperature fields during formation of dissimilar butt joints of Ti-Al alloy plates by laser welding process were investigated by numerical simulation. Gaussian volumetric heat source was applied to model the heat input to the weld. For verification of the developed simulation model and results of numerical simulation, Ti-Al butt weld joints were produced by TruDisk 4002 disk laser. During experiments, the temperatures were measured by thermocouples and subsequently compared with results of FEM analysis. Based on the results of preliminary numerical calculations and experimental tests, the parameters of the laser beam welding for production of dissimilar Ti-Al butt joints will be optimized using FEM simulations in the program code ANSYS.
