FAQs
Can a wire and a flat sheet be welded together?
Yes — the anvil supports the sheet while the horn consolidates the wire into it, making one solid joint.
Why is palladium used?
Palladium-plated surfaces resist corrosion and are common on high-reliability contacts; ultrasonic welding bonds them without damaging the plating.
Is the plating damaged?
No — the solid-state process consolidates the materials without melting the plated layer.
