Abstract

PROBLEM TO BE SOLVED: To keep the appearance and designability of a product good by eliminating thermal damage applied to the ultrasonic welding point of the product in a method and apparatus for joining two parts by ultrasonic processing. SOLUTION: An aluminum heat radiator 70 is set at a ultrasonic welding point in a receiving fixture 60, and a cooling system 80 for cooling the radiator 70 which is heated by heat from the welding point during ultrasonic welding is installed. As the cooling system 80, cooling air is ejected from an air supply pump to the radiator 70, or the heat in the radiator 70 is discharged outside by vacuum suction, the radiator 70 is cooled by heat diffusion, etc., by heat radiating fins 73 to eliminate the thermal damage on the surface side of the product.
