A METHOD FOR CONTINUOUSLY BONDING A METAL HAVING A RELATIVELY LOW MELTING POINT TO THE SURFACE OF A MOVING STRIP OF METAL HAVING A RELATIVELY HIGH MELTING POINT WHICH COMPRISES COATING THE SURFACE OF THE MOVING STRIP OF HIGHER MELTING METAL WITH A MOLTEN MASS OF THE LOWER MELTING METAL AT A TEMPERATURE ABOVE THE MELTING POINT OF THE LOWER MELTING METAL AND BELOW THE MELTING POINT OF THE HIGHER MELTING METAL, IMMERSING THE TIP OF A VIBRATORY DEVICE IN SAID MOLTEN MASS OF METAL WITH THE LOWERMOST END OF SAIF TIP BEING SPACED FROM THE SURFACE OF THE METAL HAVING A RELATIVELY HIGH MELTING POINT A DISTANCE OF BETWEEN 0.001 TO 0.085 INCH, EXPOSING THE MOLTEN MASS OF THE LOWER MELTING METAL TO A SUFFICIENT AMOUNT OF MECHANICAL VIBRATORY WAVE ENERGY HAVING A FREQUENCY OF BETWEEN 59 AND 300,000 CYCLES PER SECOND TO EFFECT CAVITATION IN SAID MOLTEN MASS AND BONDING OF THE MOLTEN MASS TO THE UNDERLYING METAL SURFACE, AND THEN COOLING SAID MOLTEN MASS OF METAL TO A TEMPERATURE AT WHICH IT SOLIDIFIES.
