Drawing on the power of high-frequency vibrations, ultrasonic welding brings unmatched speed to the process of welding thermoplastic materials and metals. This approach to welding can be incredibly cost-effective, not to mention practical, as it eschews the need for traditional fasteners.

Ultrasonic welding has come a long way in just a few short decades, and yet, it remains a mystery to many business leaders in Rochester. This practice is even more impressive when you know the science behind it. We clarify how it works below:

It All Comes Down to Friction

The high vibrations generated during ultrasonic welding make conditions favorable for binding without requiring any outside fasteners.

Vibrations are made possible by a power supply that converts electricity to a high-frequency version. This is then converted to high-frequency sound, which is finally focused by a sonotrode. Air pressure may be needed to hold materials together by force while welding.

Variations in Ultrasonic Welding

While most ultrasonic welds follow the same basic steps outlined above, the process may vary based on the selected sound frequency, the amount of pressure needed to hold items together, and the amount of time for which the ultrasound is applied. This can vary dramatically, with sound waves ranging from 20 to 40 kHz, while timing may last a few milliseconds or longer than a second.
