Method for surfacing crowns of teeth of digging machines by means of lying electrode / 2243868
Method comprises steps of placing electrodes with gap on part to be surfaced; using flux and additive powder material; exciting electric arc between electrode and surfaced surface; performing multi-layer surfacing alternatively on upper and lower sides of crown; using steel substrate whose width is equal to distance between lateral faces of crown and whose length is equal approximately to difference of length values of new and worn crowns along axis of lateral side; arranging steel substrate in direction of plane crossing axes of lateral faces of crown and welding it to crown along contour of wear; fixing crown with welded substrate in such a way that at first its upper side is arranged horizontally, then its lower side is arranged horizontally; placing electrodes across lengthwise axis of crown at first on substrate and then on surfaced zones until their complete restoration.

Method for restoring rolling rolls / 2245771
Method comprises steps of mechanically removing damaged layer and performing electric arc surfacing of rotated roll in place of damaged layer removal while feeding steel austenite wire electrode with diameter 3 - 5 mm to welding zone. Surfacing is realized at density of electric current 30 - 40 A/sq. mm and at electrode feeding speed 80 - 110 m/h. After surfacing journal is subjected to spontaneous cooling.

Surfacing machine tool / 2246384
Surfacing machine tool includes column with yoke, cross piece, carriage, face chuck, table with adjustable inclination angle, surfacing head having mechanism for reciprocation motion in horizontal plane, mechanism for vertically moving surfacing head, mechanism for rotating in horizontal plane surfacing head with mouthpiece. On surfacing head there are mounted: reel with surfacing wire, mechanism for feeding wire to surfacing zone through mouthpiece and mechanism for reciprocation motion of surfacing head in horizontal plane. Machine tool is provided with matching device having actuating organ and providing kinematic connection between mechanism for rotating surfacing head and mechanism for vertical motion of surfacing head. Handle and flywheel kinematically joined with toothed rack of cross piece are secured to carriage. Matching device is in the form of worm reduction gear of rotation mechanism that is kinematically joined through first cone reduction gear with face chuck and through set of gear wheels - with connection coupling. The last through spring of actuating organ in the form of electromagnet and through second and third cone reduction gears is joined with lead nut of vertical motion mechanism.

Machine part restoration method / 2247014
Method comprises steps of mounting on surface of part prepared for restoration before surfacing, blank of additive material in the form of band; using band with thickness 0.1 - 5.0 mm and mounting it at gap no more than 0.2 mm; performing multi-layer surfacing of additive material in vacuum by means of scanning electron beam; mechanically working part after surfacing each layer of additive material.

Method for restoring steam turbine blades / 2251476
Method comprises steps of removing worn portion and then surfacing in impulse mode metal whose ductility exceeds that of blade material; welding on protection cover strip by two seams while forming one seam on base material of blade and forming other seam on surfaced metal. Surfaced metal has high cracking resistance; its melting temperature is less than that of base material of blade. Heat treatment with use of heat insulation jacket is performed after surfacing and welding on of protection cover strips.

Method for surfacing copper or copper alloys on substrate of high-alloy nickel alloys / 2252117
Method comprises steps of placing copper plate on substrate and melting it by means of electric-arc welding with use of non-consumable electrode; before placing plates, applying flux layers onto mutually joined surfaces; insulating ( for preventing contact with arc plasma) end edges of copper plate and portions of substrate near edges of plate along the whole perimeter; realizing surfacing at melting temperature of copper plate that causes no fusion of base metal of substrate.
