Abstract

Studies have been worked on the restoration of various perishable parts with welding. The main purpose of the research is to increase the strength of the working surfaces of parts different coating by welding different types of covered electrodes. Studies have been carried out to determine the composition, structure, rigidity and eroding resistance of the welded covering material. As a result of laboratory research, the optimal composition of the covering material is determined and the optimal method of welding them to the eroded working surface of the parts is selected.
