In a MachineDesign article, Fastening & Joining: Emerson Ultrasonic Welder Is an Automation-Ready Asset, Emerson’s Kerryn Harrington shares how an upcoming product, the Branson Polaris IW Ultrasonic Welder, provides an entry-level solid-state joining method for thermoplastics, metals, textiles, and more. It supports a wide range of applications in the automotive, textile, consumer electronics, and food packaging industries.
In the article, Kerryn explains:
“Ultrasonic welding is a way to replace traditional material joining methods like glue, screws, adhesion…”
The article includes a 1:30 YouTube video, Emerson Ultrasonic Welder Provides Flexibility, with Kerryn demonstrating the quick ultrasonic welding process with two plastic pieces. She notes the strength of the bond.
“Now we went from two parts to one part. You can see it’s very strong. You cannot break it, even if you tried.”
The article explains the ultrasonic welding process.
Ultrasonic welding is a solid-state joining method that applies high-frequency vibrations under moderate pressure to bond materials such as thermoplastics and metals. Frictional heat is delivered to the interface, which disrupts the materials structure just enough to weld the pieces. There are no connective adhesives or soldering materials. To ensure a strong bond, key parameters—including amplitude, pressure, weld time and frequency—must be tightly controlled. The process is highly repeatable, and suitable for precision applications.
