ULTRASONIC WELDING

Ultrasonic welding is the most technically complicated process and just like each of the processes mentioned before, has a limited application. However, it also has a number of advantages including highly precise dosing of the amount of energy needed for welding and its supplying to a precisely defined place. Ultrasonic welding is an industrial technique of joining materials whereby high-frequency acoustic waves are used as an energy carrier. The ultrasonic wave locally applied to workpieces being held together under pressure, makes the involved materials plastic and melt. That results in a permanent connection of the parts to be welded. Ultrasonic welding allows you to combine two parts often made of various materials. In the ultrasonic welding process, there is no need to use fasteners (pins, sticks), solders or adhesive joints.

In ultrasonic welding, the heat needed for joining parts is obtained from the vibration of material particles they are made of. The vibrations are brought to one of the parts as a result of pressing the ultrasonic tool (sonotrode) against it. Then they are led through the material to the point where the details meet and vibrations are changed into the heat needed to make the connection. The heat is released as a result of mutual vibrations of welded materials and welded surfaces.

The vibrations are generated by a system based on piezoceramic transducer that can convert the voltage pulses to mechanical vibrations. The vibrations are picked up by the waveguide and transmitted to the tool. To stimulate the transmitter a generator that creates electricity of the appropriate voltage and frequency is needed.
