Abstract

The article studies the process of restoration of worn parts of agricultural machinery by submerged arc welding, defines similarity criteria characterizing this restoration process and revealing their physical essence. A technique has been developed and a general criteria equation has been obtained for determining and optimizing the hardness of the resulting metal coatings, which is the scientific basis for conducting targeted experiments. For surfacing of plowshares and other parts under flux, the existing standard installation was modified in order to automate the process and increase productivity, and several devices were manufactured taking into account the shape of the working elements being restored. Experimental studies were conducted as a result of which an analytical form of the criterial equation was obtained and rational modes for restoring parts during electric arc surfacing under flux were established. The composition and structure of the obtained metal coatings were studied and different compositions were proposed as new fluxes. obtained in Georgia using the remains of manganese processing in the city of Chiatura.
