AbstractThis article considers the nature of magnetic field density distribution from quadripolar magnetic system, applying to weld formation control during arc welding at nuclear power facilities is considered. Existence of concentration of tension in the transition from the main metal to a seam reduces corrosion resistance of welded connections and leads to corrosion cracking during the product work in hostile environment. In the following research measurement results of magnetic field induction are shown. Therefore magnetic field is hyperbolic in the field of burning of an arch and a zone of pro-melting of the main metal.
