Background
Ultrasonic welding is performed by converting low-frequency current into high-frequency electric energy through an ultrasonic generator, converting the converted high-frequency electric energy into mechanical motion with the same frequency through a transducer again, and then transmitting the mechanical motion to a welding head through a set of amplitude transformer devices capable of changing amplitude.
The ultrasonic metal welding principle is a special method for connecting the same kind of metal or different kinds of metal by using mechanical vibration energy of ultrasonic frequency. When metal is subjected to ultrasonic welding, current is not transmitted to a workpiece, a high-temperature heat source is not applied to the workpiece, and the wireframe vibration energy is converted into friction work, deformation energy and limited temperature rise among the workpieces under the static pressure. The metallurgical bond between the joints is a solid state weld that is achieved without melting of the parent metal. Therefore, the phenomena of splashing, oxidation and the like generated during resistance welding are effectively overcome. The ultrasonic metal welding machine can perform single-point welding, multi-point welding and short-strip welding on the thin wires or sheet materials of nonferrous metals such as copper, silver, aluminum, nickel and the like, and can be applied to welding a bourdon tube port and a sealing sheet of a pressure gauge.
