Modeling of heat field in weld bath with consideration of material evaporation during pulse laser welding in vacuum


G. Turichin, E. Zemljakov, E. Pozdeeva, A. Abdurachmanov

The article devoted to development calculations model for simulation of temperature field and melt pool behavior in pulse laser welding under the space conditions. The model based on 3-dimentional linear heat transfer solution in irritated material and non-linear boundary conditions on work piece surface. The superficial boundary conditions are taken follow Anisimov model of evaporation. Developed model has been used for estimated of evaporation influence on formation of weld bath in conditions of manual laser welding. More...
