METHOD OF MANUFACTURE OF TWO-LAYER STRUCTURE WITH INNER SPACES |
摘要 |
FIELD: aviation and space industry, production of radiators; manufacture of laminated structures of aluminium alloys. SUBSTANCE: sheet blanks are pressure welded over outer contour and inner space contour at temperature or 0.3-0.4 of blank material melting temperature in die by means of inserts with projections. Spaces are blown off by gas under pressure. At temperature of 0.7-0.9 of blank melting temperature, gas is fed onto their outer surfaces to carry out diffusion welding. EFFECT: improved reliability and quality of structures. 4 dwgr
