Ultrasonic Metal Welding

Branson ultrasonic metal welding is the industry-leading technology used to join components and batteries found in smartphones and electric cars.

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.
