High Power 4000w 20Khz Ultrasonic Metal Welding on Cable Harnesses

Description:

Ultrasonic welding is a special welding method that uses ultrasonic vibration (frequency over 18 kHz) to connect the same or different metals, semiconductors, plastics, and cermets.

The ultrasonic metal welding process is a process between cold press welding and friction welding that utilizes high density energy generated by high frequency mechanical vibration. The mechanical vibration of the welding head of the ultrasonic metal welding is parallel to the surface of the workpiece. During welding, the static pressure acts perpendicularly on the welding surface through the welding head, and at the same time superimposes the shearing force of the high-frequency vibration. When the shearing force exceeds the elastic limit of the material, the part of the contact surface of the workpiece begins to slip. This shearing force The direction is constantly changed at a frequency of tens of thousands of times per second during the welding process. Breaking and removing dirt on the surface of the workpiece, the surface of the pure metal begins to contact in multiple points. As the high-frequency vibration continues, the contact area of the pure metal expands until it expands into the entire weld zone, and at the same time, atoms are formed on the contact surface. Diffusion, metal recrystallization produces fine grain structure and exhibits cold metal deformation characteristics.

Automotive wiring harness ultrasonic welding precautions:

Ultrasonic welding of automobile wire harnesses is to weld a multi-strand or single-strand wire into a wire knot by ultrasonic action. The advantages are: good electrical conductivity after welding, very low or close to zero resistance coefficient; short welding time, no need for any flux, gas, solder.

Automotive wire harness ultrasonic welding should pay attention to:

1. It is best not to tin or galvanize the wire, although it can be welded in some cases, but the effect will be discounted.

2. Select the model according to the cross-sectional area of the wire.

3. Wire harness welders require good quality control software to make quality judgments for each solder joint.

4. Control mode adopts energy control mode
