2000W 20khz Ultrasonic Harness Welding machine for various wiring harness
Light weight and smart size
Ultrasonic wiring harness welding is 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.

Altrasonic series ultrasonic harness welding machine could weld the harness area from 0.5mm²to 50mm². It is mainly apply to overlap welding of automoble wiring harness cable, wire head molding,wire inter-welding,multi-wire joining-up,butt joining or cross-welding.
Altrasonic series ultrasonic harness welding machine suitable for copper-aluminum harness, metal braid wire, metal stranded wire, harness terminal, enameled wire, electric machine lead wire and harness, aluminum wire welding.
Altrasonic series ultrasonic harness welding machine are widely used in automobile, electronics and
electrical industry, communication equipment, mechanical equipment, instrumentation and other fields.
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.
Principles of Metal Welding
Ultrasonic metal welding is a fast, clean and economical way of welding.
Ultrasonic welding process is a kind of process between cold pressure welding and friction welding.The mechanical vibration of ultrasonic metal welding head is parallel to the workpiece surface.Static pressure through the welding head vertical role during welding in the welding on the surface, high frequency vibration superposition with shear force at the same time, when the shear force beyond the material elastic limit, the parts of the workpiece contact surface began to slip, the shear force in the welding process to tens of thousands of times per second frequency changing direction, broken and eliminate artifacts oil, pure metal surface in the multiple point contact, began as a continuation of the high frequency vibration, pure metal contact area expands unceasingly, until the extended to the whole welding area, at the same time in the contact surface atom diffusion, metallic recrystallization generated fine grained structure and take on the characteristics of the metal cold deformation.
● Welding materials do not melt, do not destroy metal properties
● After welding, electric conduction, good thermal conductivity, low or almost zero resistance coefficient
● Low requirements for welding metal surface, oxidation or electroplating can be welded
● Short soldering time, no flux, gas, solder required
● It is easy to realize the connection and automatic control between different metals
Welding no spark, environmental protection and safety
Comparison of welding technology
● Argon arc welding, resistance welding, current welding, intermediate frequency welding, high
frequency welding and other such welding are welding. It melts the metal together at high temperature and has changed the original properties of materials
● The laser welding principle is the same as above, relying on high-temperature fusion welding, but can be precise spot welding, note that it is a point can not be area welding
● Ultrasonic welding principle is high frequency friction welding, close to cold welding, it is the best electrical connection welding process at present, for the destruction of the parent material, until now there is no international found that a welding process can be compared with ultrasonic welding
● For the specific industry, ultrasonic welding has the advantage of no competition
● Our company independently developed quality control system, with three basic control modes of
welding energy, time and height, and a variety of quality control software to meet different demands.
Other domestic companies basically do not have the welding energy control mode,
only simple time control.
