一， Basic principle of ultrasonic metal welding machine

  Ultrasonic metal welding machine is a special method to connect the same metal or different metals by using the mechanical vibration energy of ultrasonic frequency (more than 16KHz). During ultrasonic welding of metals, neither current nor high temperature heat source is applied to the workpiece, but under static pressure, the vibration energy of the frame is transformed into friction work Deformation energy and limited temperature rise. Metallurgical bonding between joints is a kind of solid state welding realized without melting the base metal. Therefore, it effectively overcomes the splash and oxidation phenomena generated during resistance welding. Ultrasonic metal welding machine can perform single point welding, multi-point welding and short strip welding on thin wires or sheets of non-ferrous metals such as copper, silver, aluminum, nickel, etc. It can be widely used in SCR leads, fuse pieces Welding of electrical lead wire, lithium battery pole piece and pole lug.

二， Welding advantages

1) . The welding materials are non molten and non fragile.

2) After welding, the conductivity is good, and the resistance coefficient is extremely low or near zero.

3) Low requirements on the surface of welding metal, oxidation or electroplating can be used for welding.

4) Short welding time without any flux, gas or solder.

5) No spark in welding, environmental protection and safety.

三、 Applicable products for ultrasonic metal welding

1) Nickel metal hydride battery Nickel metal hydride battery Nickel mesh and nickel sheet are mutually melted and nickel sheet is mutually melted.

2) Copper foil and nickel foil of lithium battery and polymer battery are mutually melted, and aluminum foil and aluminum foil are mutually melted.

3) . The wires are fused to each other, forming one and multiple wires.

4) The wires are fused with various electronic components, contacts and connectors.

5) The mutual melting of large heat sinks, heat exchange fins and honeycomb cores for household appliances and automotive products.

6) Electromagnetic switch, fuse free switch and other high current contacts, mutual melting of dissimilar metal chips.

7) The tail sealing and cutting of metal pipe can be water tight and air tight.
