Method of centrifugal deposition by consumable electrode / 2457929
Invention is used in arc deposition by consumable electrode made from metal with fusion point lower than that of article metal. Proposed method comprises feeding consumable electrode into deposited article cavity via guide channel of rotary welding torch. Welding torch is revolved in plane, in direction of article rotation. At a time, welding torch is displaced along article rotational axis for deposition in screw line. Prior to deposition, electrode is arranged with angular shift to torch rotational axis. The latter is displaced through definite distance. For deposition by electrode made of metal with fusion point lower than or equal to that of article metal, welding torch is rotated at angular speed lower than that of article. Then, the torch if fitted inside article cavity. For deposition by electrode made of metal with fusion point higher than that of article metal, welding torch is rotated at angular speed higher than that of article. Then, the torch is removed from article cavity.

Method of reconditioning center hoes of tillage row-crop cultivators / 2443523
Invention may be used in reconditioning tillage equipment working tool surfaces.
