It was established experimentally that a normal component of induction along the side surfaces of rods of the input device of the transverse magnetic field is distributed almost uniformly (has the same values). A slight increase in the values of this induction component is observed only in the zones at the ends of rods and coils, placed on these rods. To study the distribution of transverse magnetic field induction in the welding pool zone (at the base metal surface), it was proposed to use the well-known assumption that there is an analogy between the structure of magnetostatic and electrostatic fields. On this basis, a procedure was proposed which allows calculating the distribution of transverse and longitudinal induction components of the magnetic field generated by the input device of the transverse magnetic field at the surface of welded plate of nonmagnetic materials. In this case, the known equations of electrostatics are used. It was assumed in the calculations that charges of electrostatic field on the side surfaces and rod ends of the input device of the transverse magnetic field are uniformly distributed. It is shown that the proposed method provides a satisfactory convergence of calculated and experimental data. 8 Ref., 6 Figures.
