ABSTRACT

The method of reduction of the boundary-value problem for Maxwell’s equations to a system of integral equations has been further developed for the analysis of electromagnetic processes in the axisymmetric system of the arc welding of a gap in the plate by sinusoidal current. The conditions of the process and the actual electrophysical characteristics of materials forming the essentially non-uniform media – the calculation region – were taken into account.

KEYWORDS
