Claim 1
Independent Claim
148 words
THE METHOD OF MANUFACTURING A LAMINATED METAL PANEL COMPRISING THE STEPS OF: (A) PLACING A WIRE MESH SCREEN WITH A MESH OPENING OF FROM 1/16 TO 1 INCH FORMED OF A FIRST METAL SELECTED FROM THE GROUP CONSISTING OF STAINLESS STELL AND CARBON STEEL BETWEEN TWO SOLID SHEETS FORMED OF A SECOND METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AND ALUMINUM ALLOYS; (B) HEATING SAID WIRE MESH SCREEN TO AN ELEVATED TEMPERATURE BETWEEN 1200*F.-1500*F. SO THAT UPON CONTACT WITH SAID TWO SOLID SHEETS SAID SHEETS BECOME SEMIPLASTIC; (C) APPLYING PRESSURE ON THE OUTER SURFACES OF SAID SHEETS TO FORCE THEM TOWARD EACH OTHER WHILE IN SAID SEMI-PLASTIC STATE SO THAT SAID SHEETS CONTACT EACH OTHER THROUGH THE INTERSTICES IN SAID WIRE MESH SCREEN; AND (D) THEREAFTER ALLOWING SAID SHEETS TO COOL TO FORM SOLID PHASE BONDS BETWEEN SAID SHEETS AT THE POINTS OF CONTACT BETWEEN SAID SHEETS.
