Ultrasonic Large Square Wire Harness Welding


Ultrasonic welding of automobile wiring harnesses is to weld a multi-strand or single-strand electric wire into a wire knot by an ultrasonic welding process. The advantages are: good electrical conductivity after welding, very low or nearly zero resistivity; short welding time, no need for any flux, gas, solder. But at the same time, automotive wire harness ultrasonic welding should pay attention to:

1. The wires should not be tinned or galvanized. Although they can be soldered in some cases, the effect is not as good as before.

2. Select the model according to the cross-sectional area of the wire. Ultrasonic wire harness welding machine: suitable for welding wire cross-sectional area of 0.5-40mm ;

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

4. A few questions can be used to determine whether it is doing well.: 1 ) How is the harness aspect ratio calculated? What criteria does this meet? 2 ) Does the single and second pole joints meet the mechanical strength requirements? How to control the amount of compression? 3 ) Is the metal welder modified with a plastic welding circuit used for metal welding? Metal welding machines modified with plastic welding circuits can still cope with the proofing process, but if mass production is required, then a lot of problems will come. The first is production stability.

5. The ultrasonic welding machine harness technical requirements, according to IPC standards: a wiring harness requires ultrasonic welding, thickness ratio is between 1: 1 and 2: 1 between; B wire must not show any discoloration; C may be pressing surface. Identify the outline of the strand, but there are no loose strands.

Ultrasonic wire harness welding uses high-frequency vibration waves to transmit to the surface of two wire harness workpieces to be welded. Under pressure, the surfaces of the two wire harness workpieces are rubbed together to form a fusion between atomic layers. The advantage is that it is fast and energy-saving. High fusion strength, good electrical conductivity, no spark, near cold processing
