FIELD: the invention is designed for increasing homogeneity of metal structure of welded joints of austenitic steels.
SUBSTANCE: the essence is that the ultrasonic vibrations with the frequency of 22,1-22,7 kilocycle are introduced into the zone of the seam.
EFFECT: exclusion of anisotropy and disappearance of structural disturbances in the welded seam.
