Tungsten yttrium electrodes applications for they are used in military and aviation welding, which are different from other electrodes, such as thoriated tungsten electrodes used in hardware welding. That is to say, tungsten yttrium electrodes tend to being used in military, aviatic and astronautic industries.
During welding,tungsten yttrium electrodes produce a slim arc, which is the slimmest among all tungsten electrodes. And this has been the reason that tungsten yttrium electrodes are used in military and aviation. With a high level of compression, it has a bigger melting depth in medium and high current.
