Ultrasonic transducer,ultrasonic generator and ultrasonic horn constitute a whole ultrasonic system.The applications of ultrasonic welding are extensive and are found in many industries including electrical and computer,automotive and aerospace, medical and packaging. Whether two items can be ultrasonically welded is determined by their thickness. If they are too thick ,this process will not join them. This is the main obstacle in the welding of metals. However, wires,microcircuit connections,sheet metal,foils,ribbons and meshes are often joined using ultrasonic welding. Ultrasonic welding is a very popular technique for bonding thermoplastics. It is fast and easily automated with weld times often below one second and there is no ventilation system required to remove heat or exhaust.
• Converter: converters the electrical signal into a mechanical vibration;
• Booster: modifies the amplitude of the vibration. It is also used in standard systems to clamp the stack in the press;
• Generator: applies the mechanical vibration to the parts to be welded.
