Ultrasonic Copper Wire Spot Welder
Ultrasonic Wire Bonder Spot Welder performs well in the pressure welding of heavy-duty multi-core cables, aluminum wires and copper wires in the wiring harness.
Ultrasonic Copper Wire Spot Welder performs well in the pressure welding of heavy-duty multi-core cables, aluminum wires and copper wires in the wiring harness. Ultrasonic welding is successfully used to weld enameled wires to copper terminals without first removing the enameled layer. This connection shows excellent strength and does not affect electrical conductivity. In the automotive industry, the Ultrasonic Wire Bonder Spot Welder can be used to compact multiple copper wires of different cross-sections of the wire harness. Ultrasonic welding machines currently account for the majority in the electronics and automotive industries.

Features:
Material aspect: Ultrasonic welding requires metal materials to have good flexibility (less mechanical loss during sound wave propagation), so the most commonly used materials are aluminum alloy and titanium alloy. However, ultrasonic metal welding requires wear resistance of the welding head (requiring higher hardness), which makes the selection of materials more difficult, because hardness and toughness seem to be naturally opposed, which requires us to choose materials with very high requirements. The high-quality steel we choose can better solve this contradiction.
Process: Including the processing technology and subsequent processing technology. The processing technology has been described in detail above. Subsequent treatment includes heat treatment and parameter trimming. Based on the materials selected by our company, we have the original heat treatment process to ensure that after the welding head is made, the parameters must be measured and adjusted separately to ensure the product quality.
FAQ
Q: Does the machining accuracy of the ultrasonic welding head have any effect on the Ultrasonic Copper Wire Spot Welder ?
A: Since the ultrasonic welding joint works under high-frequency vibration, it should be designed symmetrically as far as possible to avoid unbalanced stress and transverse vibration caused by asymmetric sound wave transmission (the welding joint we use for welding uses ultrasonic vibration for the whole resonance system, and the unbalanced vibration will lead to the heating and fracture of the weld wool.) Ultrasonic welding is used in different industries to meet different machining accuracy requirements. For extremely thin workpieces, such as the welding of lithium-ion battery pole pieces and lugs, as well as the coating of gold foil, ultrasonic welding can be used in different industries, and the requirements for machining accuracy are very high. All our processing equipment use numerical control equipment (such as machining center) to ensure that the processing accuracy meets the requirements.
