FIELD: process engineering.
SUBSTANCE: invention may be used in repair of structural elements using damaged area recess filling by welding. Recess 4 features outline 16 to locate structural element outer surface 13 relative to recess 4. Recess 4 is filled with a layer of beads, preferably, with the use of laser welding. To prevent joint flaws and cracks layers are applied to make beads get onto outer surface 13 outside of recess outlines 16. Several layers of beads are used for filling recesses 4 unless the last layer is completely extended beyond surface 13.
EFFECT: ruled out joint defects.
