METHOD OF PRODUCING WEAR RESISTANT WORKING SURFACE OF TILLAGE IMPLEMENT PARTS Russian patent published in 2011 - IPC B23K9/04 B23P6/00 

FIELD: process engineering.

SUBSTANCE: invention may be used in agricultural machinery for increasing wear resistance of tillage implements by fusion welding. Wear resistant filler material is built up on part working surface, which represents parallel strips with 2-4 mm-thick layer at right angle to part working surface travel direction, space apart by not over 15 thicknesses of the layer. Built-up strips may be made up of alternate different-length sections spaced apart by, at least, the built-up strip width, or identical sections spaced apart by 1 to 3 their widths, or sections with length equal to width arranged at distance between them equal to their width, or staggered with spacing between adjacent strip sections being overlapped in direction of working surface travel.

EFFECT: decreased wear rate o both main and built-up metal due to reduced friction between tool and soil.
