Question

Quizplus · Accepted Answer

Ultrasonic welding involves introducing high-frequency vibrations, typically in the range of 20 kHz to 70 kHz, into the metals being joined. This creates friction between the metals, which causes them to heat up and fuse together. It is commonly used for joining plastics and metals in various industries.
