The metals’ welding process using the ultrasonic energy is relatively simple, both by phenomenological viewpoint and as regards the practical achievement . However, the field of materials’ unconventional micro-joining technologies by ultrasonic welding know a strong development only in the last years, once by conceiving and building of some performant equipments. These equipments should ensure the reproductibility of the welded joints’ quality, automation possibilities for the manufacturing processes and their monitoring .
The advantages of ultrasonic welding are: high work speed, respectively productivity, by performing of one single operation, energetic efficiency, aesthetic aspect, high joining quality level, materials’ cost cutting by eliminating the consumables and high efficiency of the specific welding equipments .
Automotive industry is one of the industries where the production’s renewal degree is continuous and the buyers’ demands increase exponentially. The machines’ endowments are personalized, delivery terms are short and the quality level should be faultless .
The automotive wiring represents an important element, even vital for the automotive’s good operation. The hundreds or thousands of connections between wires should ensure the respective circuits’ continuity, regardless the operation regime and external conditions. Any contact fault compromises the entire assembly .
