Ultrasonic Metal Spot Welding Machine
Ultrasonic Metal Spot Welding is a well-developed and established production method for joining non-ferrous metals. Especially in the automobile industry, this reliable and trend-setting technology has been used in the production of wire harnesses for decades now. Ultrasonic metal welding is a cold, friction welding process, i.e. no liquid-melt phase occurs. The parts being joined are rubbed together at their contact surfaces under slight pressure.
Compared with crimping or resistance welding, this process offers numerous advantages. Besides the excellent electrical properties of the joint and the extremely low energy consumption, this method is particularly characterized by comprehensive process control and process data management.
Ultrasonic Welding Principle:
l Ultrasonic metal welding machine use ultrasonic frequency vibration principle to change ultrasonic vibration energy into friction energy and transfer to the metal surface to be welded ,while the friction produces heat under the pressure, the metal structure of molecules fully activation of the fusion between the molecular layer of the formation of the new equipment.
l Microcomputer control, electronic tuning frequency.
l Power adjustable, operate simple, and run stable and reliable.
l LED display keeps the machine visible in operation and regulation.
l Imported components, good performance in energy output.
l Overcurrent protection and soft start can keep the machine safe.
l Easy installation and operation.
l High-quality ultrasonic transducer, strong power, good stability.
l Good conductivity and resistivity very low or almost near to zero.
l Oxidation or plating metal can be welded.
l Short weld time, no need additional flux, gas, solder.
l No welding sparks, environment protection and safety.
l Without the need for frequent replacement of amplifier due to stepless adjustment of the amplitude.
l Low energy consumption, high efficiency, no distortion, no pollution, welding firm, and convenient operation.
l Welding material does not melt non-fragile metal properties.
l Pairs of welding metal surfaces that require low, oxidation or plating can be welded.
l Multi-layer positive and negative electrode welding for dynamic power battery
welding material does not melt, non-fragile metal properties.
l Li-ion battery and polymer battery: Copper foil welds nickel sheet; Aluminum foil welds aluminum sheet; Aluminum foil welds Nickle sheet.
l Auto splice welding, Formation of electric wire end, Welding for electric wires; Multiple electric wires bond welding.
l Electric wire and cable welding, terminal , connector , electric parts welding .
l Solar panel battery, flat solar plate , copper and aluminum plate joints.
l Solenoid switch, fuseless switch: big currency joint point welding and dissimilar metal welding.
l Refrigerator and air conditioner copper tube sealing. Vacuum parts of copper tube and aluminum tube sealing.
In addition, advances in metals technology are producing thinner and lighter metal foils and wire for use in sensitive electronics and other products. Ultrasonic metal welding can satisfy the clean and delicate requirements of these applications, whereas traditional welding methods may be much too destructive.
Ultrasonic welding also meets the reliability demands of larger, heavy-duty applications such as charging systems for electric vehicles, wind power towers and solar energy systems.
