Tungsten current carrying capacity

Tungsten current carrying capacity in addition to their chemical composition, but also by many other factors, such as the form of the torch, the polarity of electrode holders, electrode diameter, electrode shape, the type of power supply, the electrode protrudes from the torch length, welding position, the protective nature of the gas and the like. Under the same process conditions, the impact is not very different types of DC butt welding electrodes carrying capacity. Tungsten carrying capacity sizes are related to their polarity, heat about 2/3 of the produce on the anode, heat 1/3 is produced on the cathode. Therefore, under hot conditions, however, the negative electrode is much larger (about ten times) can carry a current electrode connected to the positive (reverse method) (positive connection) when; Similarly, in the case of DC power negative electrode AC current carrying capacity than the downloading of large current capacity. Alternating pure tungsten current carrying capacity than other tungsten, and current carrying capacity of all types of electrode carrier symmetrical AC waveform situations than carrying small asymmetric alternating current-carrying capacity. Huaye Tungsten and molybdenum remind the customer: select tungsten, you must be careful, choose well-known producer of tungsten, according to their need to choose the appropriate tungsten.
