THE METHOD OF EDGE-BONDING AND CLADDING METAL PIECES HAVING PAIRS OF OPPOSITE FACES; COMPRISING FORMING SAID PIECES WITH LINEARLY COMPLEMENTARY CLEAN EDGE SURFACES WHICH EXTEND SUBSTANTIALLY PERPENDICULARLY WITH RESPECT TO SAID FACES, PLACING SAID EDGE SURFACES TOGETHER IN EDGEWISE CLOSE COMPLEMENTARY ABUTTING RELATIONSHIP WITH MINIMIZED VOIDS THEREBETWEEN, PLACING CLEAN CLADDING PIECES IN INTERFACIAL CONTACT AGAINST OPPOSITE CLEAN FACES OF SAID PIECES AND EXTENDING ACROSS THE COMPLEMENTARY EDGE SURFACES TO FORM AN ASSEMBLY, LOCATING THE ASSEMBLY WHILE COMPARATIVELY COOL IN A PRESS WHICH HAS BEEN PREHEATED TO A SUBSTANTIAL DEGREE OF TEMPERATURE ADAPTED FOR RAPID SUBSTANTIAL SOLID-PHASE BONDING OF SAID PIECES, QUICKLY APPLYING A SUBSTANTIAL BUT ESSENTIALLY NONDEFORMING PRESSURE BY THE HEATED PRESS TO SAID ASSEMBLY PERPENDICULARLY TO SAID FACES OVER A SUBSTANTIAL AREA ADJACENT THE EDGE SURFACES TO PREVENT ANY SUBSTANTIAL TRANSVERSE SLIDING MOVEMENTS OF THE PARTS OF THE ASSEMBLY, SUBSTANTIALLY HOLDING SAID PRESSURE FOR A PERIOD OF TIME SUFFICIENT TO EFFECT A SUBSTANTIAL ELIMINATION OF SAID VOIDS AND GROWTH OF A SUBSTANTIAL SOLID-PHASE BOND ACROSS SAID EDGE SURFACES, AND THEREAFTER REMOVING SAID ASSEMBLY.
