ABSTRACT

The problem of the movement of liquid metal in a welding pool in arc welding process is solved in three-dimensional formulation. The velocities of liquid metal flows in the bath melt were investigated. Tetrahedral finite elements are used. Discretization of Navier-Stokes equations by coordinates in space is carried out according to the Galerkin scheme with analytical integration along the element's volume. The Eulerian inverse scheme is used to solve the non-stationary problem. Numerical results are presented.

KEYWORDS
