FIELD: mechanical engineering; compressors.
SUBSTANCE: according to proposed method of manufacture of impellers of centrifugal compressors, main disk with blades is made and cover disk consisting of two rings, outer and inner ones, with ring welded edges. Outer and inner rings are welded in turned over entire perimeter and from two sides to blades of main disk, and rings of cover disk are interconnected by girth weld. Proposed method provides welding without additional intermediate parts ensuring reliability and strength of weld joint of rings of cover disk with blades of main disk.
EFFECT: increased service life and trouble-free operation of centrifugal compressor machines.
