Thoriated tungsten welding rods have been used in TIG arc welding since 1951. The International Organization for Standardization color code of yellow and red indicates approximately 1% and 2% by weight of ThO2, respectively. Because thoriated tungsten rods contain thorium, which is a low-level radioactive material, they could pose health and ...

There are two primary types of welding electrodes, consumables and non-consumables. Consumable electrodes have a strip of filler metal inside them, which gets melted down as the rod is used for welding. It can be reused if the filler were to somehow stay intact. Non-consumable welding rods do not contain any filler material inside them.
