A METHOD OF CLADDING A STRIP OF BASE METAL, COMPRISING THE STEPS OF COVERING AN UNHEATED STRIP OF THE BASE METAL WITH A LAYER OF UNHEATED OXIDATION-SENSITIVE METAL IN POWDER FORM, CONVEYING THE UNHEATED COMBINATION IN AIR THROUGH PRESSURE ROLLS WHICH ARE HEATED TO A TEMPERAATURE IMPARTING SUFFICIENT HEAT TO THE METAL POWDER TO RAISE IT ABOVE ITS RECRYSTALLATION TEMPERATURE AND WHICH SUBJECT THE HEATED METAL POWDER TO SUFFICIENT PRESSURE TO CONSOLIDATE THE LAYER OF POWDER AND SIMULTANEOUSLY BOND IT TO THE BASE STRIP, THE TEMPERATURE OF THE ROLLS BEING HIGHER THAN THE TEMPERATURE OF THE POWDER.
