METHOD OF REMOVING RESIDUAL STRESSES IN ANNULAR WELD JOINTS OF METALS IN HIDDEN ARC WELDING AND DEVICE TO THIS END

摘要

FIELD: process engineering.;SUBSTANCE: proposed method comprises applying low-frequency vibratory oscillations during welding in direction in plane parallel with weld seam axis by two vibrators. Said vibrators operate in counter phase. The latter are located in symmetry about seam axis on each butt edge.;EFFECT: higher efficiency.;3 cl, 4 dwg
