Why this process
- Cu–Ni–Al combinations are welded in one automated cycle.
- No flux, so no corrosion risk at a Ni-plated joint.
- Automation removes operator-to-operator variation.
- Low heat protects thin foils and tabs.
Typical applications
Battery tab to busbar · nickel tab to copper foil · automated cell contacting · Cu-Ni-Al transition joints.
FAQs
Why is nickel used in these joints?
Nickel resists corrosion and welds well to both copper and aluminium, so it is common in battery tabs and contacts.
Is the cycle fully automatic?
Yes — parts are fed and welded without manual positioning in this configuration.
Can thin foils be welded without tearing?
Yes — the low-temperature vibration process is gentle enough for thin tabs and foils.
