Abstract
It is shown that at the present time the calculation methods, which allow determining induction in the weld pool zone, which is generated by two-rod devices for input of transverse magnetic field during arc welding. However, these methods are extremely difficult to use. In this paper, the calculation methods for determining numerical values of the induction components of a transverse magnetic field in the weld pool were proposed. The methods are based on the use of experimental data on the value of the induction generated by the transverse magnetic field input device in the weld pool zone at different value of rod cross-sections of these input devices. The calculation expressions and an algorithm for their use are proposed to determine the magnetic field induction components in the indicated zone. The satisfactory convergence of the calculated data with the experimental ones is shown. The methods are recommended for using in arc surfacing and welding of products of materials which are not ferromagnetics. 8 Ref., 6 Fig.
