Product Description
HF-WX-35NZ Ultrasonic Torsion Welding Machine
The HF-WX-35NZ Ultrasonic Torsion Welding Machine is engineered for high-quality joining of copper wires, aluminum wires, stranded conductors, wire harness terminals, and dissimilar conductive materials. Unlike conventional resistance welding or crimping processes, ultrasonic torsion welding creates a solid-state metallurgical bond through high-frequency vibration and controlled torsional energy, without melting the base material.
This advanced welding technology is particularly suitable for applications requiring low electrical resistance, high pull strength, and long-term reliability. It is widely implemented in new energy vehicles, battery packs, energy storage systems, wire harness manufacturing, power electronics, and electrical equipment production.
As electrical systems demand higher current-carrying capacity and more compact connection structures, manufacturers increasingly require joining solutions that maintain conductivity while reducing heat-affected zones and material degradation. The HF-WX-35NZ is specifically developed to meet these critical requirements.

Key Features
Designed for High-Current Electrical Connections
The HF-WX-35NZ is particularly suitable for electrical connections that must carry high current loads over extended periods. The welding process creates a compact connection area with stable conductivity and low contact resistance.
Solid-State Welding Without Melting
Unlike soldering or conventional fusion welding, ultrasonic torsion welding joins materials without fully melting them. The resulting connection is often stronger and more stable than conventional mechanical joining methods.
Suitable for Copper, Aluminum, and Dissimilar Metals
The machine can be used for various conductive materials, including:
  • Copper wire
  • Aluminum wire
  • Stranded conductors
  • Copper-to-copper joints
  • Aluminum-to-aluminum joints
  • Copper-to-aluminum connections
Process validation is recommended based on conductor size, material type, and performance requirements.
Compact Weld Area with High Strength
Because the welding process does not require filler materials or additional connectors, the finished joint remains compact while maintaining excellent mechanical performance. This is especially beneficial in installations where space is limited and conductor routing is complex.
Typical Applications
  • New Energy Vehicle Wire Harnesses: Suitable for high-voltage wiring systems, battery connections, and power distribution harnesses used in electric vehicles.
  • Energy Storage Systems: Used for battery module conductors, flexible connectors, and current transmission assemblies in energy storage equipment.
  • Battery Pack Manufacturing: Applicable to battery pack internal wiring, collector assemblies, and conductor joining applications.
  • Electrical Equipment Production: Suitable for power distribution assemblies, electrical control systems, and industrial conductor connections.
  • Charging Infrastructure: Used in EV charging equipment, charging cables, and high-current conductive connections.
  • Power Electronics: Applicable to inverter systems, power converters, and electrical control modules requiring reliable conductor connections.
Benefits for Manufacturers
  • Lower Electrical Resistance: The solid-state welding process creates a highly conductive connection, helping reduce energy loss during operation.
  • Strong Mechanical Performance: The welded joint can achieve excellent pull strength and vibration resistance for demanding applications.
  • Improved Production Consistency: Automated ultrasonic welding helps reduce quality variation caused by manual assembly methods.
  • Reduced Consumable Costs: No solder, terminals, adhesives, or shielding gas are required during the welding process.
  • Suitable for High-Volume Production: The process supports rapid cycle times and repeatable results, making it ideal for large-scale manufacturing.
