AWS: A5.12

Thorium Oxide (ThO2) =2% called thoria

The thoria provides about 20 percent higher current-carrying capacity, longer life and resistance to contamination of the weld. Designed for DCEN applications, low level radioactive material. Note: If electrode grinding is used the dust might be ingested, special precautions relative to ventilation should always be considered.
