Principles of Ultrasonic Metal Welding
Principles of Ultrasonic Metal Welding The principle of ultrasonic metal welding is to use the mechanical vibration energy of ultrasonic frequency (over 16KHz) to connect the same metal or dissimilar metal in a special method. When metal is ultrasonically welded, it neither delivers current to the workpiece nor applies a high-temperature heat source to the workpiece, but under static pressure, the vibration energy of the frame is converted into friction work, deformation [...]
