Numerical Simulation of the Formation Process of the Keyhole in Laser deep Penetration Welding

摘要：

In order to simulate accurately the formation process of the keyhole in laser deep penetration welding.Multiple reflection and Fresnel absorption are implemented simultaneously with the ray tracing technique in the keyhole.With all the governing equations including continuity,momentum and energy equation,the VOF method is adopted to trace the free surface of the molten pool.Simulation results are compared with the experimental ones to verify its validity.
