2060 Copper Aluminum Palladium Terminal Welding
Ultrasonic terminal and wire-harness welding demonstration.
Technical Specifications
- Model
- JHN2056
- Rated capacity
- 5600 W
- Frequency
- 20 kHz
- Welding materials
- copper, aluminium, palladium
- Max. welding area
- wire and terminal welding

Why this process
- Cu–Al–Pd stacks are joined directly, which soldering handles poorly.
- No flux means no corrosion risk at the joint.
- Low temperature keeps plated surfaces intact.
- Repeatable parameters let the same stack be welded the same way every time.
Typical applications
Palladium-plated contacts · Cu-to-Al transition terminals · plated terminal welding · precious-metal contact bonding.
FAQs
Why is palladium mentioned separately?
Palladium-plated contacts are common in high-reliability terminals; ultrasonic welding bonds them without damaging the plating, unlike soldering.
Does the plating survive the weld?
The process is solid-state and low-temperature, so the plated surface is consolidated rather than melted away.
Can the same machine weld plain copper?
Yes — the head is used for copper and aluminium wire and terminal welding as well.
