Abstract:
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% CeO_2 tungsten bar .
