ʻAʻole mākou e hoʻohana hou i ka thorium tungsten ma muli o nā pilikia olakino a palekana e pili ana i ka radioactive element thorium. Hoʻohana pinepine ʻia nā electrodes tungsten Thorized i nā noi welding, ʻoi aku ka TIG (tungsten inert gas) welding, ma muli o ko lākou hiki ke mālama i kahi arc paʻa a hāʻawi i ka hana maikaʻi i nā wela kiʻekiʻe. Eia nō naʻe, he mea radioactive ka thorium a ʻo ka hoʻohu ʻana i ka lepo thorium a i ʻole nā ​​​​huhū i hana ʻia i ka wā wili hiki ke hoʻopilikia i ke olakino, ʻoi loa i ka māmā. ʻO ka hopena, aia ka neʻe ʻana i nā mea ʻē aʻe non-radioactive e like me cerium, lanthanum, a i ʻole zirconium tungsten electrodes, i like ka hana me ka thorium tungsten akā me ka ʻole o nā pōʻino olakino pili. Kūlike kēia hoʻololi me ka hoʻoikaika ʻana e hoʻokumu i ka palekana o ka limahana a hōʻemi i ka ʻike ʻana i nā mea pōʻino i nā wahi ʻoihana.
