摘要：

In　this　paper,　the　influence　of　different　contents　of　rare　earth　oxides　of　tungsten　electrodes　on　the　welding　performance　has　been　studied.　Tungsten　inert　gas　weld　was　carried　out　on　1060　aluminum　plate,　using　different　contents　of　rare　earth　oxides　of　tungsten　electrodes.　The　content　of　CeO2　are　2%　and　4%,　the　content　of　composite　rare　earth　oxides　(La2O3:　CeO2:　Y2O3　=　1:　1:　3)　is　4%.　The　mechanical　properties　of　these　welded　joints　were　investigated.　The　results　indicated　that　the　loss　of　the　CeO2　content　of　4%　electrode　weight　was　the　maximum.　The　arc　stability　of　the　three　kinds　of　tungsten　electrodes　was　good.　The　arc　static　characteristic　curve　of　the　composite　rare　earth—tungsten　electrode　was　lower　than　that　of　the　cerium—tungsten　electrode.　The　loss　of　rare　earth　oxides　of　electrode　had　little　effect　on　the　mechanical　properties　of　welded　joints.　©　(2015)　Trans　Tech　Publications,　Switzerland.
