Ultrasonic Welding Principle/Theory Ultrasonic welding, also known as ultrasonic bonding, is a process in which high-frequency (ultrasonic) sound waves are applied to two or more workpieces that are being held together under pressure to fuse them into a single piece. Commonly used to join plastic parts—especially those made of different types of plastic—ultrasonic welding permanently … Read more
