Ultrasonic Metal Joining Device For Electric Vehicle Wire Welding

Ultrasonic metal joining technology is a kind of "cold welding", that does not melt the metal, the use of ultrasonic vibration between the metal friction movement, the friction generated heat quickly remove metal (especially non-ferrous metals) oxide layer, in a very clean interface, the infinite proximity between molecules to produce connections. That is, the high frequency and low amplitude of ultrasonic vibration are used to make intermolecular connections between metals. This joint principle also applies to welding different materials. Such as glass and hard metal welding, and steel and aluminum welding. There are also materials with high thermal conductivity properties, such as copper or aluminum and so on.

Technical Parameters:

Advantages of Dongho Ultrasonic Metal Joining Device:

1, Good electrical conductivity after welding, very low or almost zero resistivity.
2, The ultrasonic metal joining machine is close to cold processing, the workpiece is not annealing, no oxidation trace.
3, High fusion strength.
4, For welding metal surface requirements, are low, oxidation or electroplating can be welded.
5, Welding time is short, do not need any flux, gas, solder.
6, The joining process does not need water cooling and gas protection, welding parts do not deformation.

Application:

New energy vehicle industry: The pole lug welding on the lithium battery pack of electric cars is popular now, as well as the welding of wiring harness and wiring harness inside the car, and the welding of wiring harness and terminal.
The medical profession. The most typical application is pin welding on integrated circuits in medical equipment. The process does not require glue or adhesives, just the bonding of the body material. Such as pacemakers used to treat patients and sensors implanted in the body. In addition, ultrasonic welding is widely used in the manufacture of intravenous catheters, blood/gas filters, dialysis machines, valves, and filters.
Electronics and computer industry: Used in chips, motors, capacitors, flash memory, microprocessors, transformers, and other products. The welding process combines thin metal, usually aluminum or copper, with thick material to seamlessly connect wires and circuits. It can effortlessly connect circuits on a circuit board, making it ideal for the smartphone and computer industries.
Space industry: When making engine parts, non-ferrous metal materials such as aluminum are welded to steel. After welding, the components have high drawing strength, precise size, and a beautiful appearance. It can also meet the requirements of sealing performance and impact resistance of a closed chamber after welding.
Refrigeration industry: Copper pipes have been used as refrigeration and air-conditioning cooling system components. Because copper was expensive, aluminum tubes were used instead. However, regardless of whether copper or aluminum tubes are used, ultrasound can be used for sheet welding or sealing.
