METHOD FOR SUBMERGED MULTIARC WELDING OF METAL PRODUCTS Russian patent published in 2017 - IPC B23K9/18 B23K9/22

Abstract RU 2613831 C1

FIELD: metallurgy.

SUBSTANCE: welded joint welding bath is filled with successive electrodes. Ultrasonic vibrations are fed to one of welding electrodes in a welding bath at 30-70% of volume of welding bath filling with molten metal by prior electrodes.

EFFECT: invention improves quality of welded joint macrostructure in case of automated submerged multiarc welding, and also removes its internal defects in form of slag inclusions, pores.
