METHOD OF INDUCTION SURFACING Russian patent published in 2013 - IPC B23K13/01 B23K101/04 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building. Proposed method comprises placing the article in retainer for them to revolve with aligned article rotation axis and mirror axis. Spreader is arranged inside article inner cylindrical surface bottom section. Spreader is fixed relative to revolving article and with clearance relative to its surface. Then inductor is installed to start the article to revolve. The inductor is switched on to feed facing material gradually onto revolving surface to required thickness of facing layer over the entire surface area. Here speed of rotation equals that whereat facing material crumbling and melt spreading are prevented. After facing said inductor is switched off. Note that revolution is continued unless hardening of the melt. Now the built-up surface is turned to required diameter.

EFFECT: optimised process, higher quality of built-up layer.
