Tungsten Spot Welding Tip / electrodes: Due to its high melting point, tungsten ensures that even the high temperatures that occur at the particularly exposed tip cause no damage to the spray nozzle. The high level of thermal conductivity provided by tungsten and copper ensure optimum heat dissipation. As a result, our nozzles and electrodes offer excellent resistance to arc erosion. This guarantees a long service life.
outstanding arc erosion resistance
high temperature resistance
optimum thermal conductivity
Our company provides plasma sprayed copper-inlaid tungsten electrodes (also called cathodes and anodes), which are widely used in 9MB, F4 and other spray guns from GTV, FST, Metco, AMT and other companies. Our plasma spraying electrodes and nozzles are made of high-quality tungsten materials. After densification, they have fast arc starting, stable voltage and slow falling speed.
Combined with our company's unique NDB non-destructive connection method, seamless integration between copper and tungsten is achieved. Tungsten copper electrodes have good heat dissipation and strong anti-burning ability.
