METHOD OF BIMETALLIC MULTILAYER PANAL PRODUCING Russian patent published in 2008 - IPC B32B1/06 B32B15/01 B23K20/00 B64C1/12 

FIELD: production methods.

SUBSTANCE: during the producing of bimetallic multilayer panels between the sheets of trimming transverse frames and box-view profil es are installed, at the same time there is a gap between the sheets of the trimming and box-view profiles that allows for performing welding. The breadth of transversal frames is chosen with taking into account the number of additional metal the way, that during adding welding force the additional metal of the transverse frames deformed with generating of double-side fillet and the gap should disappear. The box-view profiles are the embedded details, they are not removed from bimetallic multilayer panel after the welding, and made of the metal with coefficient of liner expansion lower then the coefficient of liner expansion of the transverse frames and the sheets of trimming.

EFFECT: it is trivialized the panel producing.
