Abstract
A new quasi-three-dimensional model of the laser welding of thin metal plates and a numerical algorithm of its implementation are proposed. Computations of thermophysical processes at a laser joining of titanium plates are carried out. It is shown that the new model adequately describes thermophysical and hydrodynamic processes occurring in the welding region.
