Abstract
An experimental study is reported of the influence of capillary waves on heat and mass transfer in molten metal during gas tungsten arc (GTA)- augmented laser processing by cw CO2-laser radiation of q approximately equals 2- 4.5 MW/cm2 intensity. Capillary waves excited on the melt surface by a periodic pulsed reaction of a metal vapor jet had complex dynamics. An analysis of the experimental results indicated a considerable change in heat and mass transfer in the melt when three-dimensional vibrations were excited, compared with the processes that occur at q < 2 MW/cm2. Such changes enhanced the mixing of an alloying elements (compared with the familiar alloying methods) and established the optimal (for surface processing of metals) shape of a molten bath.
