The basics of ultrasonic welding

How does ultrasonic welding work? What is ultrasonic welding? Most people probably don't know much about ultrasonic welding, a manufacturing technique that holds two materials together, such as a hook and loop. The first patent for welding metal objects using this process was obtained in 1960. Five years later, engineers discovered that sound waves could also weld non-metallic materials. The technology uses ultrasonic, high-frequency sound waves instead of heat or electricity.

Ultrasonic welder pressing on the contacts

As the two parts are held under pressure, the ultrasonic welder emits high-frequency sound waves that pass through the material. As the waves locate the contact points, they cause the material to vibrate, creating friction that generates heat that melts the part. After the wave is complete, the part forms an elastic bond as it cools and hardens. This process does not require welding or the use of metal fasteners, adhesives or other bonding materials such as threads.

Two materials welded together

Ultrasonic welding is an environmentally friendly process that takes only seconds, consumes very little energy, and reduces costs while maintaining high quality. The device incorporates touchpoints on cell phones and other consumer electronics that are often inaccessible with other soldering methods. These techniques are applicable to a wide range of commercial and industrial applications. In the food industry, this process is used to create seals. It secures blister packs and facilitates the manufacture of a variety of products, including toys, disposable lighters, straws and IV catheters.

Ultrasonic welding application range

Ultrasonic welding is a welding method commonly used in plastics, aerospace, automotive and other industries to join similar materials. Particularly useful in the production of medical products. Since the process does not introduce exhaust gas or other contaminants, and the welds do not degrade, the manufacturing equipment can be used in a clean room environment.
