METHOD OF REMOVING RESIDUAL STRESSES IN ANNULAR WELD JOINTS OF METALS IN HIDDEN ARC WELDING AND DEVICE TO THIS END Russian patent published in 2013 - IPC B23K9/18 C21D9/50

Abstract RU 2477202 C1

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.
