Ultrasonic Metal Welding

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

Delicate or Durable: A Range of Welding Systems for Your Application

Ideal for welding nonferrous metals, Branson ultrasonic metal welding systems generate stable bonds, withstand harsh conditions and meet the production demands of consumer brands and OEMs in the automotive, HVAC, alternative energy and electronics industries. Ultrasonic metal welding is an energy efficient-process that eliminates the need for added materials or contaminants such as flux agents, solder, solvents or crimp connectors.

Ultrasonic Metal Welding Systems


Branson spot welders meet a wide range of nonferrous welding applications, including precise welding of smaller gauge metals and delicate assemblies. Our reliable systems are able to accommodate automation, which maximizes throughput while maintaining exceptional quality whether you’re producing batteries, terminals or another demanding application.


Branson Ultrasplice Systems ensure precision splicing of nonferrous wires in a wide range of sizes. Ultrasonic splicing delivers a superior electrical connection over crimping, soldering or resistance welding and reduces power consumption, eliminates consumables and extends tool life. We offer precision splicing solutions for a wide range of applications including premium automotive wire harnesses, electronics and more.


Branson’s seam-welding systems allow continuous-feed welding with no limits to material length or width. Designed to deliver superior quality, performance and efficiency, they are ideal for continuous welding of aluminum and copper foils at speeds up to 22 meters per minute. Systems are electronically adjustable to enable welding of a range of materials and thicknesses at different operating needs, including applications in solar energy, HVAC and more.


Branson Ultraseal ultrasonic systems hermetically seal copper and aluminum tubes using no heat or consumables. Designed for automation, our one-step systems are highly efficient and productive, allowing operators to crimp, seal and cut off charged tubes in less then a second. Our systems can accommodate your toughest application HVAC challenges and more.
