LAMINATE STRUCTURE MANUFACTURING METHOD Russian patent published in 2006 - IPC B21D47/04 B23K11/08 B23K20/14 

FIELD: manufacture of structures of materials capable to super-plastic deformation.

SUBSTANCE: sheet blanks of filler of titanium alloy are joined by contact welding along predetermined pattern. Cavity between them is sealed and sheet blanks of filler are placed between sheets of lining. At least sheet blanks of filler are molded by means of working fluid under controlled pressure and then filler in solid state is joined with linings. Parameters of contact welding are selected according to condition for forming such width of joining zone of filler blanks in plastic state that may prevent occurring of limit molding radius in filler blanks near seam before termination of molding process.

EFFECT: lowered degree of stress concentration in ready structure, elimination of rejections at molding.
