Abstract

In this article the dynamic model of the process of the laser welding with deep penetration based on the variation principles is presented. The model takes into account melting flow, wave motion on the cavity surface, melting viscosity, bubble pressure, recoil pressure and radiation parameters. The model predicts self-oscillation character of the cavity behavior in welding, moreover the cavity oscillations are stochastic in general case.
