Ultrasonic welding is a fast, easily repeatable, and cost-effective way to bind materials. It's especially beneficial in the medical device manufacturing industry, allowing for quick, efficient production while providing reliable welds that are safe for the end user. Learn more about ultrasonic welding with these frequently asked questions.

A Guide to Ultrasonic Welding

What happens during the welding process?

The binding power of this process comes from mechanical vibrations above the range of audibility. High-frequency acoustic vibrations are applied to two components that have been clamped together. The vibrations generate a fast buildup of heat, which creates the weld that binds the two base materials without any substantial melting.

What are its benefits?

The vibrations produce a workable accumulation of heat in about two to four seconds, a fraction of the time of other welding and adhesive methods. Because this method requires no adhesives or similar products, there is less cost, waste, and risk of contamination from chemical epoxies. This method doesn't heat the areas surrounding the weld, which makes it easy to handle the items and perform multiple welds without interruption.

What medical products use this method?

In the world of medical device manufacturing, a number of common health care products utilize ultrasonically welded parts, including syringes, filters, catheters, and sterile packaging for tools and supplies. Ultrasonic welding is also used in the creation of different types of personal protective equipment.

What welding tools are needed?

Ultrasonic welding involves five main tools. A power supply converts power to the high frequency and voltage required to run the transducer. The transducer transforms the incoming high frequency electrical signals to mechanical vibrations. The booster transfers the vibrational energy and amplifies it. The horn delivers the energy to the area to be welded, which is held in place by the anvil or nest.
