The article is devoted to the improving of technologies of strengthening components of plows by dip-transfer surfacing. A new scientific and technological approach to the increase of the resource of plow components, based on the technological processes of dip-transfer surfacing. A new optimality criterion of geometry of strengthening zones (Local coefficient of the wear rate) of the welding process has been established, which is the ratio of the working surfaces of the plow components at the measuring point to the average wear of the working surfaces of the components of plows. A design methodology for determining the Local coefficient of the wear rate has been proposed. The expediency of applying the semiautomatic dip-transfer surfacing is shown and the necessary technological equipment is developed. The technical and economic effectiveness of the wear-resistant hard-facing of the working surfaces of the components of plows by the unrecovered rollers is examined. Increase in the resource of the reinforced components was confirmed by tests. Using the technique of dip-transfer surfacing by the new technology can increase the resource of the components of plows by 200 %.
