Growing use of lightweight materials in the auto industry is forcing engineers to rethink how they splice wires and cables. While there are many technologies for directly splicing two or more wires together, including laser welding, resistance welding and soldering, ultrasonic metal welding has become a popular alternative for assembling wire harnesses.
Ultrasonic welding creates solid-state metallurgical bonds that have high conductivity. It does this without producing arcs, sparks or fumes, and without melting the metals.
