Abstract : CONCLUSIONS: The equation of dynamic equilibrium of a welding arc situated in a transverse magnetic field was analyzed. Approximate expressions are given for individual members of this equation: (1) inertia forces of the gaseous stream of the arc, (2) aerodynamic resistance of the medium, and (3) electrodynamic elastic force of the magnetic field of deformed arc column. Calculations of an arc with magnetic deformation are more difficult in connection with the necessity of solving nonlinear differential equations, which is possible only during the application of special methods. On the basis of the theoretical analysis a rated dependence was obtained between the current, the intensity of the controlling field, and the radius of curvature of the electric arc which is in a constant and uniform magnetic field.
