1. Basic knowledge of welding copper wire and copper sheet ultrasonic welding machine

Copper wire and copper sheet ultrasonic welding machine uses high-frequency vibration waves to be transmitted to two metal surfaces to be welded. Under pressure, the two metal surfaces are rubbed against each other to form a fusion between molecular layers. Its advantage is that it is fast , Energy-saving, high fusion strength, good electrical conductivity, no sparks, close to cold processing; the disadvantage is that the welded metal parts cannot be too thick (generally less than or equal to 5mm), the welding point cannot be too large, and it needs to be pressurized.

2. Advantages of copper wire and copper sheet ultrasonic welding machine:

1) The welding material does not melt, and the metal is not fragile.

2) After welding, the conductivity is good, and the resistivity is low or almost zero.

3) Low requirements on the surface of the welded metal, both oxidation and electroplating can be welded.

4) The soldering time is short, without any flux, gas, or solder.

5) No sparks during welding, environmental protection and safety.

3. Welding characteristics of copper wire and copper sheet ultrasonic welding machine: small size; light weight; beautiful appearance, good electrical conductivity after welding; reliable welding without changing the structure of the welded metal itself; high welding quality and high degree of automation of the welding machine; Good welding consistency; quality is guaranteed.

Copper wire copper sheet welding machine is an extended model of ultrasonic metal welding machine, also called ultrasonic metal spot welding machine, ultrasonic metal welding equipment, ultrasonic metal welding machine, etc. This equipment can be used for welding between copper wires and copper sheets within 30 square meters. The impedance of ultrasonic welding is almost close to zero. Compared with traditional welding, the welding place does not generate heat.

Copper wire copper sheet ultrasonic welding machine welding principle: Ultrasonic metal welding uses the energy generated by high-frequency vibration to combine the same or dissimilar metals under appropriate pressure through cold grinding and horizontal movement to infiltrate the surface molecules of the material to achieve welding. the goal of.
