Product Description

Ultrasonic Metal Welding of Copper Stranded Wire for Harness, with Cross Sectional


Ultrasonic welds are up to twice as strong as resistance welds for aluminum sheet welding. In addition, “resistance welding produces an undesirable heat-affected zone, an area in which the material structure is changed and sometimes degraded,” The heat-affected zone in steel may not have an adverse effect on the overall joint quality, but in aluminum the material is definitely degraded and weakened.

The most common use of ultrasonic metal welding is in wire-to-wire and wire-to-terminal assembly applications. ultrasonic welding produces greatly superior joints compared with crimping, soldering or resistance welding. She says wire harness manufacturers report a great improvement in quality at a cost reduction of 50 percent or more when switching from the crimp-and-solder method to ultrasonic welding of copper wires.

The ultrasonically welded joints are stronger and have better electrical conductivity, “Weight is reduced by eliminating the mechanical crimp. Resistance welding for wire harness applications requires 20 times the energy than that used for ultrasonic welding.”

Welding copper tubing for HVAC and instrumentation is another common ultrasonic application.This is a quicker and better method than the crimp-to-close and braze-to-seal method, “The tube can be ultrasonically welded while under coolant charge.

ultrasonic metal welder is based on principle of ultrasonic vibrations. Two metal parts are held between Ultrasonic vibrating tool horn & knurled fixture. At a time pressure is provided vertically to the vibrations. Due to this, parts ate scrubbed against each other oxide layer is being removed & two parts get joined.

So Welding is being done without losing properties of material & without adding any proper

Ultrasonic welding is cold welding process. It is being applied to metals such as copper, brass, aluminium, tin, silver, gold, platinum. Ultrasonic metal welding has used for various application in industries for electrical joints, contacts, soldering, solar panel welding compoite pipes making from strips.
