The property of WP electrode, WY electrode and WRex .electrode. WP(pure W elctrode) is the cheapest one ,suiting the welding of Mg, Al and other alloy . It has the following features: the lower steam pressure ,the little resistance, the better conductivity, the small expansion and higher elasticity.. |

WY electrode takes long and narrow arc with strong compression in welding ,especially in the middle and large current .,mainly used in the military and aerial fields. WREX electrode is a kind of electrode by adding two or more rare-earth oxides to reach the satisfied welding property. |
