The shape of welded joints directly affects the quality and stability of joints, so the weld shape prediction has great significance and engineering value to for process parameters selection. A mathematical model of fiber laser welding temperature field simulation is proposed for weld shape prediction in this paper. A new hybrid heat source model with double ellipsoid heat source and linear attenuation peak heat is applied, and the simulation process is conducted on Fluent 14.0. The simulation results are in good agreement with the experimental results, which demonstrates the proposed hybrid heat source can more accurately simulate the weld shape. Meanwhile the use of structured hexahedral mesh reduced computer storage space and the amount of computation greatly in ensuring the accuracy, thus raising the simulation speed eventually.
