METHOD OF ALUMINIUM ALLOYS PULSE-ARC WELDING BY CONSUMABLE ELECTRODE Russian patent published in 2015 - IPC B23K9/09 B23K33/00 B23K103/10

Abstract RU 2553769 C2

FIELD: process engineering.

SUBSTANCE: invention relates to welding of aluminium alloys. Invention can be used in ship building, aircraft engineering, and rocketry, etc. X-like profile of welding edges is formed to perform multipass welding with weld thickening. Every edge comprises central linear section connected by arc-like sections with inclined linear external sections. Arc-like section is curved to radius R=(0.30÷0.50)β, while central linear section is shaped to c=(0.05÷0.10)β, where β is welding edges depth.

EFFECT: higher static strength and fatigue strength of welds.
