Summary
"This dissertation presents a unified mathematical model which can be used to simulate the heat and mass transfer during the gas metal arc welding process. An interactive numerical method has been developed to calculate the complex transport phenomena occurring during the transient coupling between the arc plasma and the metal domain. The droplet is treated as an internal obstacle while the arc plasma transport phenomena are calculated, and conversely the calculated arc plasma velocity and temperature are employed as the boundary conditions for the iteration and calculation of the metal domain. The shape and size of the droplet is determined by the balance between electromagnetic force, arc pressure, plasma shear stress, and surface tension. The Volume of Fluid (VOF) method is used to handle the free surfaces of the droplet and the weld pool. The predicted trends, such as the arc plasma distribution, the droplet flight trajectories and droplet velocities, are generally in agreement with published data. The modeling results are presented in three parts"--Abstract, leaf iv
