The results for submerged arc overlaying coatings of parts of agricultural, transportation, construction and forest machinery are achieved. The highest wear resistance was achieved through DUR 600 solid wire electrode, FBTT flux and intermediate alloy of Lin- colnweld 860 flux. The wear of the coatings is very slightly increased for long period of time that provides conditions for long-term predic- tions about their general condition and remaining resource.
