Claim 1
Independent Claim
109 words
THE METHOD OF PRODUCING A HARD-SOLDER JOINT BETWEEN TWO STRUCTURAL METAL COMPONENTS, PARTICULARLY OF A NUCLEAR REACTOR, WHICH COMPRISES THE STEPS OF DEPOSITING A SOLDER COATING UPON THE JUNCTION SURFACE OF A FIRST ONE OF THE TWO COMPONENTS BY REACTION-FREE DEPOSITION, HEATING THE SECOND COMPONENT TO A TEMPERATURE ABOVE THE MELTING POINT OF THE SOLDER COATING, PLACING THE HEATED SECOND COMPONENT IN INTIMATE CONTACT WITH THE COATED AREA OF SAID FIRST COMPONENT WITH THE LATTER INITIALLY IN COLD CONDITION AND SIMULTANEOUSLY DISCONTINUING THE HEATING OF SAID SECOND COMPONENT, WHEREBY THE RESULTING HARDSOLDER BOND HAS AN EXTREMELY THIN TRANSITION TEXTURE BETWEEN THE SOLDER AND THE MATERIAL OF SAID FIRST COMPONENT.
