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

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for increasing wear resistance of outer cylindrical surfaces. Proposed method comprises arranging the article to be surfaced horizontally. Note here that two plates are fitted atop the article in symmetry about vertical and radially relative to the article. Said plates are made of heat-resistant non-metal. Spacing between said plates equals the width of a single built-up layer. Portion of surfacing metal is applied between said plates and treated by inductor. Melt hardened the article is turned through surfacing pitch. Then, first plate as seen along turning direction is moved to the place occupied by the second plate. Second plate is removed. Surfacing material is applied between surfacing layer and rearranged plate and processed by inductor. Then, surfacing cycles are repeated over the article circle. Now the built-up surface is turned to required diameter.

EFFECT: optimised surfacing.
