Abstract：

RE-tungsten　electrodes　of　W-La2O3-Y2O3　,　W-La2O3-CeO2　and　W-Y2O3-CeO2,　each　of　which　was　activated　with　two　combined　additions　of　rare　earth　metal　oxides,　are　prepared　by　means　of　powder　metallurgy　and　press　processing.　Their　welding　arc＇s　characteristics,　including　arc　starting,　arc　static　characteristics　and　electrodes＇　consumption,　were　studied　with　DCSP　TIG　welding　in　which　the　tungsten　electrode　is　negative,　and　were　compared　with　that　of　tungsten　electrodes　of　W-La2O3,　W-CeO2,　W-Y2O3　and　W-ThO2.　The　results　suggest　that　the　welding　arc＇s　properties　of　RE-tungsten　electrodes　combined　with　two　additions　of　rare　earth　metal　oxides　are　superior　to　that　of　W-La2O3,　W-CeO2,　W-Y2O3　and　W-ThO2　electrodes.
