Abstract
It has been established that increase in the content of oxygen and nitrogen in the weld metal has a negative effect on ductility of welded joints in heat-resistant nickel alloys at a working temperature. The range of the content of oxygen and nitrogen in the weld metal, within which the quality formation of the weld and satisfactory mechanical properties of the welded joints are provided, has been determined for repair microplasma powder welding.
Keywords: microplasma powder welding, cladding, heatresistant nickel alloy, welded joint, content of oxygen and nitrogen, short-time mechanical properties
