Description:

Ultrasonic wiring harness welding is the use of high-frequency vibration wave to the two welding wire to be welded surface. In the case of pressurization, the two wire harness surfaces are rubbed against each other to form a fusion between the molecular layers. The advantages of ultrasonic wiring harness welding are high-speed, energy saving, high fusion strength, good conductivity, no spark and close to cold working. The disadvantages of ultrasonic wiring harness welding are metallic parts can’t be too thick(generally less than or equal to 5mm ), the welding bit can’t be too big and need to be pressurized.

Principle:

The principle of ultrasonic welding is generated by the ultrasonic generator tens of kilohertz ultrasonic power through the magnetic transducer to produce ultrasonic vibration of the mechanical frequency. The welding cutter is set in the proper position of the end, and the chopper must produce a mechanical vibration called alternating shear stress. Aluminum wire and chip aluminum welding surface of the oxide film is damaged, and because of friction, the interface produce a certain amount of heat to the welding of aluminum wire and the aluminum pad on the chip has a certain plastic deformation, the aluminum atomic metal contact close to form a strong bond.

Advantages:

 1. High fusion strength;

 2. Close to the cold processing, the workpiece is not annealed, no oxidation traces;

3.Good electrical conductivity after welding, resistance coefficient is very low or almost zero；

4.On the surface of the welding metal is low, oxidation or plating can be welded；

5.Welding time is short, without any flux, gas, solder;

6.welding is no spark which is environment-friendly and safe
