JHNSONIC Releases Technical Guide: Ultrasonic Welding for High-Voltage EV Harnesses
As EV platforms move from 400V toward 800V, crimping is reaching its limits. Our new guide shows — with measured data — why ultrasonic welding is taking over.
- 1–3 μΩ — contact resistance
- < 1 sec — per weld cycle
- Cu + Al — dissimilar-metal ready
Large cross-section ultrasonic welding delivers ultra-low, stable resistance and metallurgical bond strength for high-voltage EV harnesses — supporting 800V platform requirements where crimping can no longer guarantee contact quality.
