Model of Quasi-Steady Weld Pool Dynamics and Numerical Simulation,terial. The welding process can be optimized in three aspects: determining a set of process parameters which make the welding process basically stable and reproducible; monitoring the changes of various parameters in the welding process to ensure the quality of the joint; real-time control of the pa

Coupling Model and Numerical Computation Method of Keyhole and Weld Pool,ing. A self-consistent heat source model dependent on the transient three-dimensional keyhole profiles is presented by using the ray tracing algorithm. Governing equations for three-dimensional transient heat transfer and fluid flow of weld pool and keyhole free surface tracking are given in detail.

Simulation of Transient Keyhole and Weld Pool,del. Transient keyhole dynamics and its physical characteristics as a function of welding parameters are presented. Transient weld pool dynamics under a stable keyhole as well as an unstable keyhole condition are also characterized by high resolution numerical simulations. The influence of physical

Dynamic Behaviors of Metal Vapor/Plasma Plume Inside Transient Keyhole,eed plasma/plume dynamics based on compressible Euler flow assumptions are given. Characteristics of the time dependent plasma/plume behaviors such as uneven distribution, multiple flow directions, strong oscillations and local evaporations at keyhole wall are found and discussed by numerical simula
