WELDED JOINT PRODUCTION PROCESS Russian patent published in 1994 - IPC

Abstract RU 2021088 C1

FIELD: welding of materials. SUBSTANCE: process includes welding and forced deformation of parts. The forced deformation is performed after the welding through the effect on a piezoelectric or magnetostrictor rendered by pulsed electric or magnetic field of constant polarity at a pulse frequency equal to the frequency of inherent mechanical oscillations of the piezoelectric or magnetostrictor. Pulsed field promotes relaxation of internal stresses in the joint area and in the piezoelectric or magnetostrictor. EFFECT: high quality of a welded joint. 3 dwg
