What is torsional ultrasonic welding?

In fact, torsional welding is sometimes found to be the only solution for electric car battery manufacturers and in the termination of high-voltage cables. Other examples where torsional ultrasonic welding proves to be the superior method are bus bars, 3D terminals and integrated gate bipolar transistors (IGBT).

What is torsional welding & how does it work?

With the Telsonic PowerWheel, torsional welding provides such gentle vibrations that studies show the effect is much less for both stranded cables and flexible busbars, depending on the terminal designs (see figure 9). This allows shorter cables and appropriate connectors be welded together.

What is ultrasonic welding?

Ultrasonic welding technology is a proven joining process that is increasingly specified by carmakers for use in EV for cables to terminal connections, busbars, battery manufacturing and power electronics. Linear welding is the more traditional and well-known technique used by all equipment manufacturers as a standard process for splicing wires.

Why do EV welds require high power ultrasonic oscillations?

The larger conductor / termination sizes and cross sections involved in EV applications require high power ultrasonic oscillations using Telsonic’s Torsional technology to deliver high levels of energy within very short process times to produce the weld.

What is the difference between a torsional and a strong joint?

Torsional energy is gently exerted on the area of the joint, thus suitable even for highly sensitive parts. On the other hand, even very strong forces may be applied in a very short time, which is critical, for example, for joining aluminum or copper foils.

What are the limitations of linear welding?

However, like many other joining processes, linear welding comes with limitations in size, difficulties welding in smaller areas and certain geometrical shapes, problems with orientation of welding, and vibration effects on peripheral components.
