Explore the evolution of joint-making technologies in EV battery production used to create efficient battery pack joints.

Ultrasonic welding is based on high-frequency vibrations (typically between 20 and 40 kHz) that cause surface friction and viscoelastic heating at the weld. The most important process parameters are ...

Continuous ultrasonic welding was used to weld the stringers to the in-situ solidified thermoplastic aircraft skin - a world first. The resistance welding process, which was further developed by DLR ...

Optimizing these processes is essential for achieving sustainable car plastic welding. Ultrasonic and Laser Welding: These ...
