The results of studying the formation of welded joint in electric arc surfacing on copper by the wires, providing a deposited metal based on iron and nickel, which according to the authors and publications in the technical literature have a high resistance to different types of wear at elevated temperatures. The modes were selected and technologies of arc surfacing on a copper basis by selected wires were developed, which provide a satisfactory formation of the deposited metal and its fusion with the base metal. According to the results of experiments on electric arc surfacing on copper, as well as the study of macro- and microstructure of deposited specimens, it was shown that the best results in terms of welding and technological properties are provided by the use of nickel-based wire. The permissibility of individual defects that were found in the deposited metal and on the fusion line of the base and deposited metal during studies will be determined by the operating conditions of specific parts. 8 Ref., 1 Tabl., 8 Fig.
