METHOD OF MULTIPASS AUTOMATIC ARGON-ARC WELDING OF PRODUCT OUT OF LOW ALLOYED STEEL OF PEARLITE CLASS WITH THICKNESS OVER 30MM Russian patent published in 2016 - IPC B23K33/00 B23K9/173 B23K31/02

Abstract RU 2574902 C1

FIELD: metallurgy.

SUBSTANCE: with layer by layer groove preparation filling of the welded product the welding of lock passes using the welding consumables with increased content of the deoxidizing alloying elements, such as Si, Mn, Al etc.

EFFECT: increased quality of the welded joint, improved plastic and strength properties of weld metal due to porosity prevention up to development of the reaction of the welding pool metal boiling, exclusion of gas inclusions, and formation of the uniform fine structure of the welded joint, wherein using traditional welding equipment and standard welding consumables.
