Develop and implement standard operating procedures for the use of thoriated tungsten electrodes, including proper procedures for storage, grinding, use, housekeeping and Thoriated tungsten electrodes contain a minimum of 9730% tungsten and 170 to 220% thorium Thorium addition increases the electron emission qualities of the electrode, which improves arc start Tips For Selecting Tungsten Electrodes [TIG Welding]

TIG Welding Linde formerly Praxair

Use an alloyed tungsten electrode to increase current carrying capacity If thoriated tungsten is selected, ensure all grinding dust is captured and removed from the It comes to us by way of [The Metalist], who turned an electric die grinder into a pencil sharpener for tungsten electrodes What we find fascinating about this build is the fabrication methodsPut The Perfect Point On Your Tungstens With This

Thoriated Tungsten Electrodes American Welding Society

During the grinding of the thoriated tungsten electrodes, radioactive dust is created, posing the potential hazard of internal radiation exposure by inhalation or ingestion unless care is taken to control the dust HOW TO REDUCE EXPOSURE • Choose thoriumfree tungsten electrodes such as those containing zirconium whenever possibleThe grinding should be done straight and not at 90 degrees That way, you ensure that the grind marks run the length of the electrode A truncated tip is used in pure tungsten, ceriated, Tips For Selecting Tungsten Electrodes [TIG Welding]
