Most forestry machines and mechanisms operate in adverse conditions: an abrasive medium at low temperatures, which impede lubrication of parts and components of mechanisms and affect the mechanical characteristics of metals; under significant loads caused by working conditions in the forest. Therefore, the issues of operation and repair of precisely logging machines are most relevant. Scientific research and best practices of repair enterprises currently have a significant number of studied methods for building up worn parts in the recovery process. Scientific research and best practices of repair enterprises currently have a significant number of studied methods for building up worn parts in the recovery process. The requirement to ensure high productivity of the extension operation is relevant and important. The most high-performance methods are metallization, casting, electro contact, surfacing. But the first two methods do not provide guaranteed adhesion to the base metal. When applying metal to a worn surface by surfacing, good adhesion and the possibility of obtaining a wear-resistant surface are ensured. When floating metal overhead, technological work is performed, which means “work to change the shape, properties, condition and position of the subject of labor. “Productivity of the equipment is determined by the amount of technological work performed for a certain period of time.
