Abstract

Procedure for powder recharge welding of metal parts with metal tapes that fuse to the electric arc, with the formation of weld beads with a width greater than 75 mm, preferably greater than 100 mm, characterized in that the tape-shaped electrode, attached to the pole of a direct current source, during the fusion process is accompanied by a stationary magnetic field, the lines of force that come out of the magnetic poles being essentially curved towards the surface of the workpiece in such a way that in the region of the marginal zones of the welding tape, each having approximately 1/20 to 1/4 of the width of the welding tape, the positive charge carriers in the electric arc are deviated in the direction of movement weld, but obliquely outward, so that the width of the layer is increased by 2 to 15 mm, compared to the bead width without influence po r magnetic field.
