The ultrasonic welding technology is an innovative method to produce hybrid joints for multi‐material components.Ultrasonics can be used to weld metals, but are typically limited to small welds of thin, malleable metals, e.g. aluminum, copper, nickel. The benefits of ultrasonic welding are that it is much faster than conventional adhesives or solvents. The drying time is very quick, and the pieces do not need to remain in a fixture for long periods of time waiting for the joint to dry or cure. The welding can easily be automated, making clean and precise joints; the site of the weld is very clean and rarely requires any touch-up work. The low thermal impact on the materials involved enables a greater number of materials to be welded together.
Ultrasonic metal much powerful than the ultrasonic plactic welding , so it required more on the ultrasonic transducer, the out put power of the transducer much higher. and good cooling system, also stability of the transducer is important. One difference between ultrasonic welding and traditional welding is the ability of ultrasonic welding to join dissimilar materials. The assembly of battery components is a good example of where this ability is utilized. When creating battery and fuel cell components, thin gauge copper, nickel and aluminium connections, foil layers and metal meshes are often ultrasonically welded together.Multiple layers of foil or mesh can often be applied in a single weld eliminating steps and costs.

Description:
The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.
Transducer requirements will depend on the application. Many requirements will conflict with one another and will be given different priorities. Hence, no single set of guidelines can encompass all requirements - i.e., there are many different ways to achieve the same objectives.
Analytically, transducer performance can only be predicted in a general way. This is because the properties of piezoelectric ceramics are often highly dependent on the operating conditions including temperature, electrical field strength, static compressive prestress, dynamic stress, number of load cycles, and time. These operating conditions can interact with each other and the effects of these conditions are often nonlinear. Also, many properties of piezoelectric ceramics are orthotropic and can vary among the individual ceramics and also between ceramic lots. Further, the interactions at the various component interfaces (e.g., at threads) may be difficult to characterize and the coefficient of convective heat transfer for air cooling may only be approximately estimated. Hence, much of the design process involves experimental testing.

15Khz transducer widely used in high power welding&sealing system.Piezoelectric transducer is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. It is key point of all ultrasonic equipment.The transducer decide the property of the machine.We can supply transducer, also transducer with house and booster.
