Thermohydrodynamic models of laser irradiation of metals examines models of continuous- and recurrent-pulse irradiation under conditions of dimensional and thermochemical treatment. Hydrodynamic mechanisms of melt displacement under conditions of dimensional and thermochemical treatment. Hydrodynamic mechanisms of melt displacement under conditions of laser drilling are discussed and the space-time structure of temperature in metal under the effect of a moving recurrent-pulse heat source is studied analytically and numerically. A thermo-hydrodynamic model of the welding process is analyzed and the two-dimensional problem of the heating of metal and melt motion under vapour pressure and surface tension is modelled numerically. Convective stirring of an admixture under the effect of pulsed laser radiation is considered and numerically investigated.
