Rybalkin E. The development of mathematical models of electromagnetic effect on the liquid metal in the underwater arc welding

Dissertation is devoted to the development of mathematical models of electromagnetic effect on the liquid metal in the underwater arc welding with an external electromagnetic influence on the basis of the method of integral equations. It is considered three-dimensional and axisymmetric problem statement. Designed axisymmetric integral mathematical model of electrodynamic processes in the arc welding with an external electromagnetic effect on the basis of its software package for finding the electrodynamic forces in the liquid metal of the weld pool and predict the behavior of the movement of the metal itself and the quality of the weld.
