WELDING OF LAPPING JOINTS OF DIFFERENT METALS Russian patent published in 2015 - IPC B23K9/23 B23K33/00 B23K103/18

Abstract RU 2542938 C2

FIELD: process engineering.

SUBSTANCE: invention relates to welding of overlap joints and can be used in power production, motor production, ship and railway car building. Power supply is connected. Plasma-forming protective gas is fed. Arc is excited at top element to penetrate both elements. Note here that top element features higher density that that of lower element metal. Depths of top and bottom elements are related as 1:3. Note also that elements are assembled to overlap by at least tem depths of bottom element while welding time is set (2…4)δ seconds where δ is total depth of the elements, mm.

EFFECT: reliable weld.
