Technical Field

Background

Ultrasonic metal welding is a solid phase welding technique. In the welding process, a welding tool head (ultrasonic welding head) applies pressure and high-frequency ultrasonic vibration to metal to be welded, so that the metal interface generates severe friction and plastic deformation to promote the interface to form good connection.

Ultrasonic metal welding is a special method for connecting the same metal or different metals by using mechanical vibration energy of ultrasonic frequency, when the metal is subjected to ultrasonic welding, the metal does not transmit current to a workpiece or apply a high-temperature heat source to the workpiece, only under static pressure, the mechanical energy is converted into internal energy, deformation energy and limited temperature rise, and two base metals are subjected to solid-phase welding at the crystallization temperature. 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 widely applied to welding of silicon controlled rectifier leads, fuse pieces, electric appliance leads, lithium battery pole pieces and pole lugs.
