OUTER WALL FOR RAILWAY VEHICLE CAR BODY AND METHOD FOR ITS MANUFACTURING Russian patent published in 2015 - IPC B61D17/04 

FIELD: transport.

SUBSTANCE: invention relates to transport facilities. To manufacture outer wall (1) or outer wall module for railway vehicle car body the flat-made metal sheets (10, 11) with different properties are connected in outer sheeting (3) made as self-supported module of stiffening panel. The metal sheets (10, 11) are put one to another with their butt ends adjoining and connected by continuous laser welds (13) thus forming free from displacements outer surface (18) on outer side of stiffening panel module. Carcass (4) is manufactured of carcass profiles which are fixed by laser welds (13) on outer sheeting (3). Metal sheets (10, 11) with different properties (15, 16) include the first metal sheets (10) and the second metal sheets (11), where the latter have higher resistivity: strength and/or thickness (15) of material, than the first metal sheets (10), and the second metal sheets (11) are built in the area of outer sheeting (3) with increased tensions. Body includes at least one outer wall or outer wall module manufactured according to the mentioned method.

EFFECT: higher reliability, reduced weight.
