FIELD: process engineering.
SUBSTANCE: invention relates to welding. Proposed process comprises application of cyclic vibratory load to welding pool crystallisable metal, load frequency being varied in an application cycle by linear law from 50 to 250 Hz. Pattern of oscillation input by vibratory device is defined proceeding from part sizes and geometrical features.
EFFECT: more efficient removal of residual strains developed in welds, higher strength and reliability of welded structure on the whole.
