Numerical Simulation of GMAW Process Based on Level Set Method

Abstract:

A model based on level set function is proposed to predict gas shielded arc welding. The model describes not only the free surface tracking of molten drop and metal transfer in gas metal arc welding, but it simulates the phase change on substrate during heat transfer，which is based on porous media theory. The result of simulation shows that this model can describe the drop diameters, transfer frequency and the shape of solidification precisely.
