Ultrasonic welderis anindustrial process whereby high-frequency ultrasonic acoustic vibrationsare locally applied to workpieces being held together under pressure to create a solid-state weld. There are many types of ultrasonic welder based on application. For example, digital ultrasonic welding machine,ultrasonic welding plastic machine, ultrasonic wire welder, and hand held laser welding. In this article, we will tell you what goes into Ultrasonic terminal welding machine.

Ultrasonic terminal welding is awell -developed and established production method for joining non-ferrousmetals. Especially in the automobile industry, this reliable and trend-setting technology has been used in the production of wire harnesses fordecades now. Ultrasonic terminal welding is a cold, friction welding process,i.e. no liquid -melt phase occurs.

Featuresof Ultrasonic Metal Welder

Low requirements onthe terminal surface,no need to scrape offthe oxide layer or electroplating layer.

The welding material does not need to be melted,does notchange the material characteristics,and has no pollution.

The welding is firm and reliable,and the resistance afterwelding is very small or close to zero,and the conductivity is good.

Equipped with high-performance ultrasonic metal spot weldingpower source,automatic tracking of transducer frequency with two control modesof time and energy.

Working Principle

Ultrasonic metal welding machine use ultrasonic frequencyvibration principle to change ultrasonic vibration energy into friction energyand transfer to the metal surface to be welded ,while the friction producesheat under the pressure, the metal structure of molecules fully activation ofthe fusion between the molecular layer of the formation of the new equipment.

Applicationof Ultrasonic Metal Welding

Copper foil welds nickel sheet; Aluminum foil welds aluminum sheet;Aluminum foil welds Nickle sheet.

Auto splice welding, Formation of electric wire end, Wireand other metal end welding。

Electric wire and cable welding, terminal, connector,electric parts welding.

Solar panel battery, flat solar plate, copper andaluminum plate joints.

Solenoid switch, fuseless switch: big currency jointpoint welding and dissimilar metal welding.
