Why Is Ultrasonic Metal Welding Essential For New Energy Vehicles?

1. Low-temperature process throughout: prevents thermal damage to films, insulation layers, battery cell electrodes, and semiconductor chips.
2. Weld joint properties (conductivity and thermal conductivity) closely match the base material; minimal contact resistance ensures no overheating under high current.
3. Reliable welding of dissimilar metals (aluminum, copper, nickel, nickel-plated steel) without forming brittle intermetallic compounds.
4. No flux residue or halogens; prevents corrosion or circuit failure during long-term use.
5. Forms an integrated structure post-welding; resistant to vibration and thermal cycling, meeting automotive-grade standards for 10-year durability.
