Our ultrasonic metal welding machines provide precise, reliable and efficient bonding of conductive materials without solder, flux or excessive heat. Designed for stability, repeatability and ease of automation, they offer strong joints with low electrical resistance and minimal impact on sensitive components, making them ideal for high-volume industrial production.
These systems are widely applied in automotive wire harnesses, battery tabs and busbars, copper and aluminum strips, and electronic connectors. Our product range covers dedicated wire harness welders, battery tab and foil welding systems, sheet and strip welders, as well as customized ultrasonic solutions to meet specific customer requirements.
The features of our ultrasonic metal welding machine
Ultrasonic metal welding works on the principle of high-frequency vibration. The welded joints feature extremely low resistance and excellent electrical conductivity. As a low-temperature process, ultrasonic welding has minimal impact on the workpieces.
The equipment allows precise control of energy, time, and pressure during welding. It can easily switch settings for different materials and joint sizes, and is capable of storing up to 100,000 welding records.
Ultrasonic welding does not require melting or additional filler materials to bond metals, meaning there are no consumables. The equipment is easy to maintain, with no need for frequent replacement of wear parts (the four-piece welding set), resulting in low operating costs.
The welding process is extremely fast, with each weld taking only fractions of a second, and it generates no harmful gases during operation.
Why choose KoneTech ultrasonic metal welding machine
The advantages of KoneTech ultrasonic metal welding machine
High-Precision Power and Frequency Control
Our ultrasonic welding generator adopts a fully digital control system with real-time frequency tracking, amplitude compensation, and automatic tuning.
This ensures stable energy output, consistent vibration performance, and prevents resonance drift even under continuous operation.
The result is precise control of welding parameters — energy, time, amplitude, and power — for consistently reliable weld quality.
Advanced Acoustic and Mechanical Structure Design
The converter, booster, and horn assembly are engineered using Finite Element Analysis (FEA) to achieve ideal vibration balance and amplitude uniformity.
All components are made from high-strength titanium alloy, ensuring high conversion efficiency (>95%), low heat generation, and long service life.
This structural optimization allows stable welding of copper, aluminum, and dissimilar metals while minimizing wear and mechanical fatigue.
Intelligent Pressure and Process Control
A closed-loop pressure control system, powered by servo or pneumatic feedback, ensures precise downforce adjustment during each weld.
Combined with real-time monitoring of energy, displacement, and time, the system automatically evaluates weld quality and issues alarms when deviations occur.
This enables repeatable results, full process traceability, and consistent welding quality in high-volume production.
Modular Design and Industrial Reliability
The system’s modular architecture allows easy integration into multi-head workstations or automated production lines.
Built-in protections against overcurrent, overheating, and overvoltage safeguard both equipment and operators.
Designed for 24/7 industrial environments, our ultrasonic metal welding machine delivers stable performance, low maintenance, and long-term reliability.
