Main thermophysical processes in laser beam buildup welding of metal powders

Autor: M. G. Galushkin, A. I. Misyurov, V. Ya. Panchenko, I.N. Ilichev, V. V. Vasil'tsov

Publikováno v: Inorganic Materials: Applied Research. 5:199-203

The energy balance of laser beam buildup welding of powders is analyzed. Comparison of the obtained results with the experimental data shows that a significant portion of the absorbed power of the laser beam is consumed for evaporation the of powder.
