METHOD TO RECOVER AND STRENGTHEN PLOUGHSHARES BY ELIMINATING RADIAL WEAR VIA TWO-LAYER BUILDING-UP Russian patent published in 2009 - IPC B23P6/00 B23K9/04 

FIELD: process engineering.

SUBSTANCE: invention relates to repair of machinery and welding, namely to the method to recover and strengthen ploughshares by eliminating radial wear via two-layer build-up. Proposed method comprises building up worn-out working surface by electrode material. Here, building up of two different-hardness layers is performed along the radial wear axis. First layer is built up by electrode with carbon content in steel rod not exceeding 0.1% and rolls of plastic built-up metal are produced with their height set depending upon the depth of radial wear. Second layer is built up by wear-resistant electrode to the thickness smaller than that of the first layer.

EFFECT: higher strength and wear resistance.
