How Ultrasonic Metal Welding Works

Ultrasonic Metal Welding

Ultrasonic energy has been used to join metal materials for decades. In ultrasonic metal welding, dissimilar materials are joined together without the use of applied heat or electric current passing through components. 

Ultrasonic energy can weld through contaminates to create a clean seal while providing increased quality and control. To achieve a high-quality seal, one part is held stationary while the second part is compressed beneath a vibrating horn. The material reaches a plastic state where molecules mix between the two parts, bonding the materials.  

Conversion Sequence

The ultrasonic welding process converts electrical energy into mechanical vibrations causing the metals to join. In the ultrasonic stack, the converter transmits the energy through the booster causing the horn to vibrate. The converter is made up of piezoelectric ceramic disks that expand and contract at the same frequency of applied electrical energy. The booster increases or decreases the amplitude of the vibrations to provide the optimum amplitude for the material, size and type of assembly.


Ultrasonic metal welding is used in a wide variety of industries including the Medical, Automotive and Electronics industries.  Ultrasonic metal welding is an effective solution for a broad range of applications.
