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.
