A physical model of laser welding process is presented. At the beginning of this paper a short characteristic of correct modeling procedure is shown. In the further part, the form of beat transport in laser welding is described. Finally the cylindrical - involution - normal (C-1-N) beat source (H-S) model and the Fourier - Kirchhoff partial differential equation are made and discussed.
