ultrasonic welding


Cars & Driving

  • noun a high-tech welding procedure used for metals (e.g. in wire bonding of integrated circuits) and plastics


  • A process in solid-state welding wherein the metal parts are held together under pressure and joined by applying high frequency sound waves to their surface.


  • Welding in which ultrasonic waves join surfaces, without the generation of heat. Used, for instance, for surfaces which can not, or should not be heated.
  • Welding which is enhanced by ultrasonic waves. The ultrasonic vibrations help remove oxides and otherwise better prepare a surface for welding, making a flux unnecessary.
