About the problem of construction of a dynamic model of weld pool in electric arc welding
G.I. Leskov, S.V. Pustovojt
E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.Abstract
Theoretical and experimental investigations of weld pool in comparison with an existing quasi-static model are analyzed. Contradictions and drawbacks, typical of this model, are outlined. The more perfect dynamic model was constructed and described on the basis of available data, laws of motion of liquids and gases and equations of electrodynamics
Keywords: arc welding, weld pool, electromagnetic and aerodynamic forces
