METHOD OF MAKING SANDWICHED PANELS Russian patent published in 2015 - IPC B23K20/14 B23K103/14 B21D47/04

Abstract RU 2555260 C2

FIELD: process engineering.

SUBSTANCE: invention can be used in aerospace engineering for production of sandwiched panels from titanium alloy VT-23. After preliminary annealing of filler sheets at 680°C and holding in air for 25 minutes said sheet blanks are stacked. Said sheets are locally interconnected by electric contact welding by several continuous perpendicular seams and stack is sealed all over its edges. Said stack is arranged between sheets of lining and heated to 875°C for shaping and welding of filler with lining by gas feed under pressure. Said preliminary annealing of filler sheets executed under above said conditions ups the stress velocity sensitivity index.

EFFECT: higher strength of finished products of titanium alloy.
