High Power 20Khz Ultrasonic Metal Spot Welder for Wire Flat Cable Welding
 
 
Description:

Ultrasonic welding of non-ferrous metals (such as copper and aluminum) is a proven welding technology in the industry that has been tested for many years. Ultrasonic welding is extremely fast and takes only 1 to 3 seconds, depending on the size of the welded joint. Compared to other welding processes, when using ultrasonic welding technology, the joints heat up less and therefore do not reach their melting point. This gives it many advantages not found in other connectivity technologies. It also does not damage other materials nearby, such as wire insulation. These include simple wire and busbar connections, wire and contact soldering in the automotive and electronics fields, and special applications for enamel winding wires, films and sheets, and in the transition to solid materials, the joints do not embrittle. . The higher welding strength is produced by the relaxation process of the first two atomic layers of the component to be welded. The welding method is similar to diffusion welding and has a wide variety of applications in the metal field.
 

Principle: 

The principle of ultrasonic metal welding is to transmit high-frequency vibration waves to two metal surfaces to be welded. Under pressure, the two metal surfaces rub against each other to form a fusion between molecular layers, which has the advantages of being fast and energy-saving. High fusion strength, good electrical conductivity, no sparks.

Parameters: 

Transducer Technology:

In principle, the transducers used in metal welding equipment and the transducers used in plastic welding equipment are not very different. The particularity is that the welding metal has higher quality requirements because it often needs to be very large when welding metal. The instantaneous power, which requires the transducer to have high power capacity and low impedance, is not the same as that commonly used in plastic welding devices.
 
 
Precautions of Ultrasonic metal spot welding :
 
Ultrasonic metal spot welding is widely used in a wide range of applications, including automotive components, high and low voltage electrical appliances, and electronic components.
1. Ultrasonic metal welding is generally less than 5 mm thick due to attenuation during ultrasonic transmission.
2. The function of the grain is anti-slip, and the shape of the welding head and the texture are determined according to the workpiece size, material and amplitude requirements. The working weight is the key consideration, and the reason is the amount of inertia.
3. It is important to consider the resonance that the ultrasonic vibration will form. The resonance will cause the weldment to break and desold.
4. The fixture design must not violate the ultrasonic principle.
5. Ultrasonic welding skills can also be destroyed, and energy control is required.
