[Lindsay] has a wonderful writeup about a new toy in the shop, an ultrasonic transducer. The 28kHz, 70W bolt-clamped Langevin transducer by itself is not much use, you need a power supply, a horn t… ...

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 ...

At the heart of ultrasonic plastic-welding machines is the transducer assembly — often referred to as the "stack." The stack typically consists of three components: the converter, booster, and ...

In plastic welding, conventional LINEAR ultrasonic welding heads are arranged vertically and use a converter, operating at between 20kHz and 40kHz together with a booster, to increase the amplitude.

This power-amplifier pair drives piezo and ultrasonic transducers for industrial and medical applications. The MP111 controls a pulsed 50-A output current on a 100-V single-ended supply and 500 ...

The transducer is designed to work within a small band of frequencies — a 40kHz transducer will not work very well if you try to drive it at anything other than it’s resonant frequency.

Similar to ultrasonic welding, MM-Welding uses high-frequency vibration from an ultrasonic stack — which typically comprises a piezoelectric transducer or converter, a booster that modifies the ...

PAWTUCKET, R.I. - Welding isn't just for aircraft carriers anymore. The U.S. Navy could be turning to ultrasonic welding to make its uniforms lighter, stronger and cheaper. And if the project by a ...
