6500W Ultrasonic Wire Harness Welding Machine For Copper Wire
Product Description
ACEY-UWM-20-6500 ultrasonic wire welding machine is designed for joining conductive wires and metal strips in battery module assembly and industrial wire harness manufacturing. It uses high-frequency ultrasonic vibration combined with controlled pressure to create solid-state metal joints without conventional soldering.
For lithium battery applications, this machine is configured for welding copper wires to nickel-plated copper strips. Typical applications include main module connection wires and cell connection system (CCS) wiring. The welding tooling and process parameters can be selected according to the wire size, material combination and required joint dimensions.
Operating at 20 kHz with a rated power of 6500 W, the system features a DSP circuit, ICS digital control, a pneumatic welding head and a 7-inch touchscreen. Operators can adjust ultrasonic amplitude, select energy or time welding modes, and recall stored parameters for previously validated welding processes. The separate welding head and ultrasonic generator simplify equipment layout and maintenance. Automatic frequency tracking and built-in electrical protection functions support stable operation
Application
- Copper wire to nickel-plated copper strip welding in lithium battery modules
- Main electrical connection wires in battery module assembly
- CCS (Cell Contact System) wire connections
- Automotive wire harness manufacturing
- Industrial electrical wire and cable assembly
Final material compatibility, tooling selection and welding quality should be verified using the customer's actual workpieces before mass production.

FAQ
Q1: Can this ultrasonic wire harness welding machine be used for lithium battery module assembly?
Yes. The ACEY-UWM-20-6500 is configured for selected battery module applications, including copper wire-to-nickel-plated copper strip connections used for main module wiring and CCS connections. Actual compatibility should be confirmed through sample welding.
Q2: How do we choose the correct welding tooling for different wire sizes?
The upper welding horn and related tooling must match the wire size, material combination and required joint geometry. Different wire sizes, such as AWG 8, AWG 12 and AWG 20, require their corresponding tooling and validated process settings.
Q3: Can the machine connect to a factory MES system?
The machine provides welding result output and an MES interface. Before ordering, customers should confirm the required communication protocol, data fields and integration requirements to determine the appropriate connection configuration.
