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.
