The welding of carbon brushes and carbon brush wires mainly usesResistance spot welding machineButt welding machine for welding, it is widely used in power tools, cars, motorcycles, electric motors, generators, small kitchen appliances, shavers, and electric vehicles.
The main function of carbon brush is to conduct electricity while rubbing against metal. It has good commutation performance and long service life. Carbon brushes are used on the commutator or slip ring of the motor. As a sliding contact body for conducting and incoming current, they have good electrical conductivity, thermal conductivity and lubrication properties, and have certain mechanical strength and commutative spark instinct. It is an important component of the motor. It is widely used in various AC and DC generators, synchronous motors, battery DC motors, crane motor collector rings, various types of welding machines, etc. With the development of science and technology, the types of motors and the working conditions they are used in are becoming more and more diverse. Therefore, various grades of brushes are needed to meet these requirements. Therefore, the welding of carbon brushes and carbon brush wires is becoming more and more important.
Key points for spot welding of carbon brushes and carbon brush wires
1. Small carbon brushes and small-diameter carbon brush wires can be welded with a precision pneumatic spot welder with a low power of about 10KVA. Large carbon brushes and large-diameter carbon brush wires require an AC spot welder of more than 50KVA or a medium-frequency spot welder. 2. Tungsten electrodes must be used for welding. Flat tungsten electrodes have no traces, while conical electrodes have dents. 3. Since it is a small piece, there is generally no need to install an additional chiller to pass water for cooling. 4. Using high current for short time welding has good effect.
