Metal Stranded Wire Welding by 20Khz 4000w Ultrasonic Metal Welding
Machine
Principle:
Ultrasonic copper terminal welding machine uses ultrasonic metal
welding principle to weld wires, copper wire, cable, copper strand,
copper wire, copper weaving wire (copper wire), copper terminal and
copper end piece. In the car occupation and electronic motor
occupation, it is possible to weld wires of different sizes to the
terminal blocks, so that the welding of the wires in the car wire
and the electronic profession reaches the best effect. Detailed
performance in copper wire and copper plate welding, motor terminal
welding, copper wire and terminal soldering, enameled wire and
terminal soldering, copper and terminal soldering, copper and
copper end piece soldering, car wire harness soldering, car
terminal soldering, copper crimping Terminal soldering and contact
switch soldering, used in detail in electronic components of
electrical appliances and cars, electronic connectors on steering
wheels, wiper switch components, car airbags, etc.

Comparative analysis of ultrasonic welding process of terminal
block and traditional crimping:
At present, most domestic enterprises usually use the crimping
process in the processing of terminal and wire harness welding. The
quality of the processed products is also relatively common, and it
is difficult to apply to some high-end high-standard products.
There are several reasons.
1. The tensile test is not closed. Loose, broken, and cracked
phenomena occur during actual use. When Tesla tested the charging
piles in Nanjing, it was because the welding strength of the
terminals was short and the explosion occurred.
2, poor electrical conductivity, high resistivity.
So if the company wants to produce some high-end terminal products,
what welding process should it use? Today, I will talk about the
ultrasonic welding process with everyone.
The principle of ultrasonic welding is very simple, that is, the
generator emits high-frequency electric energy, and the electric
energy is converted into mechanical vibration by the transducer,
and after being adjusted to the resonance frequency by the horn, it
is transmitted to the contact surface of the welding workpiece
through the ultrasonic special welding head.
When the high-frequency vibration occurs at the two metal contact
faces, the temperature rises instantaneously, the metal surface is
fused, and the metal molecular structure is mutually fused; under
the pressure of the external force. The two metals are tightly
joined together.
This soldering process occurs very quickly, usually in about 1
second, without the need to add flux, solder, shielding gas, etc.
The surface of the weld metal does not need to be treated in
advance, and all oxides and contaminants are removed in high
frequency vibration.
There is no spark in this process, residue splashing and soot, it
can be said that it is the most environmentally safe and safe
welding technology.
