METHOD OF DECREASING RESIDUAL STRAIN IN WELDED METAL JOINTS Russian patent published in 2011 - IPC B23K37/00 C21D9/50 

Abstract RU 2424885 C1

FIELD: process engineering.

SUBSTANCE: invention relates to welding, particularly, to method of removing residual strain originating in welded parts. Vibration oscillations are applied in lengthwise direction in vertical plane perpendicular to welded seam axis bi two vibrators operated in counter phase at 50 to 300 Hz with amplitude of 0.8-1.0 mm and arranged in symmetry about welded seam axis on both welded edges.

EFFECT: higher efficiency.

3 cl, 3 dwg
