摘　　要：对比了1%CeO_2和2%CeO_2铈钨棒作为氩弧焊电极使用时耐烧损性及引弧可靠性,指出了用1%CeO_2铈钨棒取代2%CeO_2铈钨棒不仅有利于提高制品成材率,也将进一步改善其电极使用性能。The burned-resistant and reliability of initiating-arc in GTAW for 1% CeO2 and 2% CeO2 tungsten bar have been compared in this research. It has been suggested. that the tungsten bar with 1% CeO2 has a lower burned rate during manufacturing and better electrode performance in GTAW than the 2% CeO2 tungsten bar.
