Processing of Pure Tungsten Electrodes

Processing of Pure Tungsten Electrodes Picture

Pure tungsten electrode can be processed by the method of powder metallurgy.

The pure tungsten electrode processing is similar to pure tungsten.The basic processes are pressing, sintering,and forging. The surface treatment of pure tungsten electrode can be cleaned, ground and polished.

Pure tungsten electrode argon arc welding electrode is used first, but in DC welding conditions, the variety can not afford electrode arc or maintenance prone to instability, adding rare earth oxides can greatly improve this situation.therefore, pure tungsten electrode only as welding electrodes under AC conditions or as a resistance welding electrodes.
